Martin Kompf An important part of a weather station is to measure the air pressure with a barometer. Air pressure and barometer Passage of a low pressure area. At the falling air pressure edge top , the measured rainfall significantly increases below. Our weather is significantly influenced by the air pressure and the associated flows. High air pressure is usually for sunny and dry weather, while a low pressure system is bringing rain and storm with it. Significant changes in the air pressure within a short time signal an impending change in the weather. The measurement and recording of air pressure is therefore a useful and worthwhile activity for the amateur meteorologist. A barometer measures the air pressure that is built up by the weight of the atmosphere at a particular place. Apart from the weather it also depends on the height of the place. In order to obtain comparable air pressure values for meteorological purposes, the measured barometric pressure is always converted to sea level Normal-zero.
Wiring relays with Flow sensors
Before we get into the software part lets hook up the 24LC chip up to our Arduino. Using the image above as a guide lets begin to wire the chip. Next lets go ahead and connect the data pins to the Arduino board.
The BMP is a new generation digital barometric pressure and temperature sensor from Bosch this tutorial, we will briefly review this device and describe how to interface it with an Arduino Uno board for measuring the surrounding temperature and pressure.
The ESP also includes a built-in The developer, Espressif , in Shanghai, China, has chosen to take full advantage of manufacturing efficiencies of scale and offer a single IC that is suitable for use on a variety of PCB assemblies. Click the photo for a larger image. A very active community support forum exists for the ESP , and is an excellent source for ideas and information.
Originally, documentation was only available in Chinese, and firm application information can still be hard to come by. Currently, many DIY projects are operating in the “trial and error” mode, but there are many aftermarket suppliers who are selling development platforms and accessories. However, as you will see later in this article, it’s not difficult to get an ESP up and running on a solderless breadboard. Programming Options From the supplier, many maybe all of the ESP modules are loaded with “AT” firmware, and can be programmed via a simple terminal program.
A more sophisticated option is available from NodeLua , which offers open source firmware based on the Lua programming language. NodeLua is still in development, but already contains extensive capabilities. There are two LED’s: Usually, two 4-pin male headers are inserted in the rear of the module and soldered on the front.
There is an alternative way as shown below.

Hookup Diagram for Adafruit BME breakout board using I2C and Alternative Address (0x76) To enable the alternative address we need to connect the SDO pin to ground. In the software when we create the BME object we need to define the address. If no address is .
It is possible to collect data from various sensors, devices or services and react to evaluated envent and start the predefined process. These systems are closely connected with Cloud based services as they provide publicly accesible interface for management and visualization, coputational and storage cababilities for forecasts and other advanced data processing to create ambient intelligence environment.
The true ambient environments react to the presence of people and the sensors and actuators have become part of the environment. The system architecture is designed to be so simple at hardware level to support sigle-board microcontrollers like ESP , ESP32 modules as well as sigle-board computers based on ARM or x86 architectures. The communication among devices is handled by the standard MQTT message bus.
This platform can perform wide range automation use cases. These range from simple environmental automations, surveillance, to complete ambient intelligence environments. First chapter introduces global architecture of autonomous agents with communication protocols for messages to the overlaying event driven controllers, dashboards or any other services. These systems use scalable and modular architecture to minimise the computational overhead which allows efficient use of available hardware resources.
The next part covers the autonomous agents in more details.
Arduino LESSON 21: Log Sensor Data to an SD Card
Hot glue Hookup wire We chose the ubiquitous Arduino Nano for its impressive control, along with a 4-position DIP switch that functions as the user interface. Opto-isolators work much like relays, but instead of mechanical switching, the control hardware the Arduino in this case powers an LED inside the chip. The emitted light then switches an entirely isolated circuit the camera via a phototransistor.
Hookup Diagram for Adafruit BME breakout board to Arduino using SPI. We can use 5V or V for the power supply. Just make sure you connect it to the appropriate pin on the breakout board. We can wire up SPI in two ways. We can use the SPI hardware pins which in .
We are now ready to move on to more advanced projects. While that was a great project, we finally ran out of horsepower with the arduino, and what we could do was limited by the memory limitations on the Arduino. Also, it is very hard to parse strings in the Arduino IDE, so interpreting the NMEA sentences is a rather large challenge with the limited string functionality in Arduino. Python on the other hand makes quick work of string manipulation and the Beaglebone Black has plenty of horsepower for any manipulation of the NMEA sentences we might want to do.
The video below takes you through the project step-by-step, as well as the description below. Once you get your gear, you will want to hook up the following circuit: Our goal in this first lesson is to establish a connection between the GPS and the Beaglebone, and to read in the data streaming from the GPS.

Data sheet BMP Digital pressure sensor BMP Data sheet Document revision Document release date 5 April Document number BST-BMPDS
A great little sensor But it may still have Good Stuff for you. I hope to “fancy it up” in due course. Worth what you paid for it. And anyway, it doesn’t require a 3v3 Arduino. I’ve had many “weather stations” over the years. Tracking barometric pressure seemed cool. You can also use the device to make an altimeter.
First 2 Prototypes Completed I made a couple of design changes to the protoype watch in my YouTube video. I also switched to the ATmega p. It is Arduino compatible and has 16k RAM!!!!!!!!!
The BMP Breakout is a barometric pressure sensor with an I 2 C (“Wire”) interface. Barometric pressure sensors measure the absolute pressure of the air around them. This pressure varies with both the weather and altitude. Depending on how you interpret the data, you can monitor changes in the.
I used to work with LCD such as HD but they are very consuming on power view and big, and as my projects are smaller and smaller on PCB view I needed quick and small displays. This is why I put this kind of connector on ArdpuiPi board. Check this post if you want more details and source code. So I started to find a new one. And most of all it is using the same controller SSD so the same code could be used without any modification except I2C address.
This OLED have an unbeatable price. Really nice job and sharing.

December 27, at 2: An alternative — if you want to have an automatic dat logging process — would be to have a timer do the automatic closing for you when a certain time has expired and open new file with a new, automatically created different filename and reset the time to zero. Thanks Paul for your very instructive tutorials.
The BMP is the next-generation of sensors from Bosch, and replaces the BMP The good news is that it is completely identical to the BMP in terms of firmware/software – you can use our BMP tutorial and any example code/libraries as a drop-in replacement.
It works on all devices — laptops, tablets, small-footprint smart phones, iPad, iPhone, Samsung… Lots of changes, device friendly and fully secure. Yes — Jotiz uses SSL SHA-2 certificates and the protocol is https — which means your communication with the website is completely secure. It has remained free from the beginning; it will remain free for all users without any advertisements as long as possible.
In an unrented garage in a small town suburban home, Jotiz had a small beginning. It was and the rains were incessant. It had no name I can remember; it was a mere astrology software.

Final Prototype Yeah, right Here is the assembled watch in it’s case. Note, I changed the watch face from the previous prototypes. I love having a watch that is totally customizable. This current version is different from the last because, instead of using an IMU board with the 3. This has reduced the thickness to be able to mount the whole project in the iPod nano case.
The battery is sitting on the outside of the case but adds so little to the width it is nearly undetectable.
Barometric Pressure Sensor Module
March 25, Library Nightmare Jadi, di postingan kali ini saya akan bercerita mengenai progress dalam pengerjaan modul ESP. Nah, tetapi tugas yang diberikan untuk dapat melakukan pertukaran data melalui modul ESP masih belum berhasil kami lakukan dan masih banyak bertemu kegagalan. Oleh karena itu, di postingan kali ini, saya akan bercerita mengenai kegagalan yang kami alami dan mimpi buruk tentang library yang masih menghantui hingga pagi.
Arduino and BMP hookup The IO in sensor board represents I/O voltage and we can leave disconnected unless connecting to a lower voltage microprocessor or micro controller. Connect ‘+’ terminal to the Arduino’s V pin.
The FreeIMU library now supports all the versions up to v0. By default it’s configured to be used on v0. In order to use on different boards, open the file FreeIMU. The FreeIMU library also supports the following 3rd parties boards: Note for FreeIMU v0. In order to use the library with HMC v0. In order to use them, Download and install Processing. Copy the folders within the processing folder of the FreeIMU library archive into your Processing sketchbook.
Remember to change the Serial port address in the Processing code to match the address used by arduino on your system. This does slow down the sampling rate. Without the quaternion print, the code completes in less than 10mS, so the sampling rate is exactly Hz as set by the timer. More details and possibility to contact the author on the FreeIMU community development forum.
Have you ported the FreeIMU library to other platforms?
