BME280 High Precision Temperature and Humidity Sensor Probe Cable OEM 1M 2M 3M 5M Digital Sensor I2C Interface Waterproof Shield

The BME280 is a digital humidity, pressure and temperature sensor. The BME280 achieves high performance in all applications requiring humidity and pressure measurement. These emerging applications for home automation control, in-door navigation, fitness and GPS refinement require both high accuracy and low TCO. Humidity sensors provide extremely fast response times for fast context-aware applications with high overall accuracy over a wide temperature range. This pressure sensor is a barometric pressure sensor with extremely high accuracy and resolution, and much lower noise than the Bosch Sensortec BMP180. The integrated temperature sensor has been optimized for low noise and high resolution. Its output is used for temperature compensation of pressure and humidity sensors, and can also be used for ambient temperature estimation.

Two kinds of signal output:

1. Standard I2C interface. The default address is 0x76

(If you need the 0x77 address, please contact us.)

2, RS485 signal output. (This device follows the Modbus protocol, using commands 03 and 06. Command No. 03 is used to read the temperature, humidity and atmospheric pressure, and command No. 06 is used to set the address, etc.)
