Crowtail – BME280 Atmospheric Sensor 2.0 – temperature, humidity, and pressure sensor with I2C interface, 30–110 kPa

Description

The Crowtail – BME280 Atmospheric Sensor 2.0 module is an integrated environmental sensor that enables simultaneous measurement of temperature, relative humidity, and atmospheric pressure. Based on the Bosch BME280 chip, it communicates via the I2C interface and can be powered with 5 V (3.3 V logic). Thanks to its compact size and very low current consumption, it is suitable for portable applications, home automation systems, weather forecasting, and indoor/outdoor navigation. It can also be used to estimate approximate altitude above sea level.
