Description
The BME280 3in1 Digital Sensor Board is a highly reliable and accurate weather sensor that can measure Temperate, Humidity and Pressure Sensor. It is based on the popular BME280 chip by bosch. This sensor module is simple to use, pre-calibrated and don’t require extra components so you can start measuring relative humidity, temperature, barometric pressure & approx. altitude in no time. This board is the successor to sensors like the BMP180, BMP085 or BMP183.
This type of sensor board uses the i2c interface so it process data fast and using only 4 wires to interface in the microcontroller.
