Grove Temp/RH & Barometer Sensor (BME280)

Grove Temp/RH & Barometer Sensor (BME280)

R 552.92



Grove Temperature, Humidity, and Barometer Sensor (BME280) is a breakout board for Bosch BMP280, a high-precision, low-power combined humidity, pressure, and temperature sensor. The air pressure can be measured in a range from 300 hPa to 1100hPa with ±1.0 hPa accuracy, while the sensor works perfectly for temperatures between - 40℃ and 85℃ with an accuracy of ±1℃. As for the humidity, you can get a humidity value with an error of less than 3%. As the atmospheric pressure changes with altitude, it can also measure the approximate altitude of a place. We can calculate the altitude with ±1 meter accuracy, which makes it a precise altimeter as well. It can be connected to a microcontroller with I2C (integrated with Grove socket) or through an SPI bus. We have also provided a highly abstract library to make this more product easier to use.

The BME280 is an upgraded version of BMP180, and BME280 gets dramatic improvements from BMP180. BME280 comes with a smaller footprint, lower power consumption, lower noise measurements, higher resolutions for pressure and temperature, lower RMS noise, a newly added SPI bus, more measuring modes, a higher measuring rate, and a newly added filter against environmental interference. Since the atmospheric pressure reading is affected by altitude and temperature, we have added compensation features. Hence, Grove - Temp&Humi&Barometer Sensor (BME280) will be more reliable in providing precise temperature, atmospheric pressure values, humidity, and approximate altitude data.

Highlighted Features

  • High-performance environmental detection: With the help of the BME280 module, it can simultaneously detect temperature and humidity, air pressure, to achieve a stronger detection effect.
  • Robust measurement range: The sensor can operate normally from -40 to 85 degrees Celsius. And atmospheric pressure sensor measurement range is from 300 to 1100 hPa.
  • Higher measurement accuracy: Only ±1.0°C error when measuring temperature, measure humidity with ±3% accuracy and measure atmospheric pressure with ±1.0 hPa accuracy.
  • Grove unified socket: The sensor ensures "Plug and Play" and could be versatile for various applications.
