AZDelivery GY-BMP280 I2C IIC SPI BMP280 Digital Breakout Barometric Air Pressure Temperature Sensor Module Board 5V 3.3V compatible with Arduino and Raspberry Pi Including E-Book!

⚛️ The board is very small, about the size of an adult fingernail. It comes with a set of header pins, but you will need to solder them yourself. This makes breadboarding an option, or directly soldering some wires to the component. I decided to go with soldering, as I can either remove the pins if required or just use some female headers. There is a free eBook available, although you will have to put in some address details to obtain the download. Just remember to grab the correct version for your language.🌡️ It was simple to connect it to an ESP8266 board after remembering to configure the Ic2 bus in ESPHome and listening for the device on channel 76. Surprisingly, the temperature reading was fairly accurate straight out of the box. I may need to compensate the readings slightly, but maybe it is not enough to bother with.🌡️ Pressure readings for 5 metres altitude were reported as 1031hPa, so compensating for sea level makes this 1030.4hPa, giving a calculated pressure of 1025.108hPa at my altitude of 42 meters. The device read 1027.1hPa, which is close enough, even if the device temperature was warmer than outside.✔️ I am quite pleased with the device, which connects easily to my prototype setup in Home Assistant.

Initially wiring up, I noticed this board cannot take 5V from the arduino and when it does, it gets extremely hot! Programming the board was also interesting, I had to change some settings in the BMP280 library in order to get this module to communicate.Once it does communicate, the air pressure seems correct and calibrated however I believe the temperature is reading 1 or 2 degrees higher, this is an easy fix in the code though.Overall, great module, good price.

Works just fine connected to a Raspberry Pi 3. Header is easy to fit and pins are marked on the back, and the markings on the PCB are still visible when the header is fitted. A minor point, this board doesn't seem to have the same pin-out as most other examples or the ones that are in many tutorials. Now the main reason I marked it down, try as I might I couldn't get the English version of the E-Book to download. Whatever I do I get the German version. Also please note another minor point, many of these BMx280 boards include a humidity sensor, this one does not.

I was looking for a product that would be useful in constructing a self balancing robot. The MPU-6050 was easy to connect, and it was easy to pull the programme and library files together. Within 20 minutes I had it running on an Arduino Uno, and chugging out the temperature, and the accelerometer and gyro data in x, y and z axis. It put a smile on my face.

Good documentation on Amazon product page. Very easy to use with microbit MakeCode blocks (there is an extension). I used this code to read the pressure (see photo) - you need to divide the reading by 100 to get mbar units. My readings agree to within 10 mbar of a nearby weather station.

No problem getting it to work. Prompt delivery. Will use this supplier in future.

Was looking for BME280 not BMP280

Do NOT purchase this item for use with Arduino Uno or any 5V micro controller, you will damage the sensor. Very underhand of the seller to say suitable for Arduino and then just slip in the voltage range at the end.
