BME-280 Temperature, Humidity and Barometric Pressure Sensor for Arduino.
This is a breakout board with a Bosch BME-280 combined temperature, humidity and barometric pressure sensor, mounted with all components necessary to connect to a Arduino, Pi, ESP8266 or other micro-controler via an I2C interface. Hookup is simple, and standard libraries are available online. The board is tiny, yet very capable and easy to use.

Technical details:-
Specifications Size Including Pins 14mm x 10mm x 10mm Weight 1.5 Grams Operating Voltage 1.8 - 5V DC Humidity Sensor Range: 0-100%, Accuracy: 3%, Resolution: 0.008% Temperature Sensor Range: -40-80°C, Accuracy: 1.0 °C, Resolution 0.01°C Barometric Pressure Sensor Range: 30,000-110,000 Pa, Accuracy: 12 Pa, Resolution: 0.18 Pa Interface I2C : Address 0x76 (can be modified to 0x77)
We recommend the use of the "Sparkfun BME-280" library for this sensor - it is an optional library in the Arduino IDE, simply search in the Library Manager and install directly. Both the Adafruit and Sparkfun libraries default to I2C address 0x77, however these devices have I2C address 0x76. With the Sparkfun library this is specified in the example sketches so is easily changed- where the Adafruit library hard codes the address, so the library header files have to be edited.
