Fermion: ENS160+BME280 Environmental Sensor

SKU: SEN0335

This multi-function environmental sensor combines ENS160 + BME280 chips, featuring high accuracy, I2C interface, and fast measurement. BME280 provides temp/humidity compensation for ENS160 to boost accuracy. It detects temp, humidity, barometric pressure, altitude, TVOC, eCO2. ENS160 (ScioSense) monitors indoor IAQ (TVOC, eCO2, AQI) with TrueVOC™ + MOX tech (superior accuracy, fast response). BME280 integrates temp, humidity, barometer: ±0.5℃ temp error, ±2%RH humidity error, small size, stable performance.

    • FAQ

    • We keep getting the output "bme begin failed, device not detected" I have checked the ICP addresses multiple times and tried different pins.

      Please check if you power this sensor with 3.3V.
      And please send us your test video if you still have successful in using the sensor.

    • Why the sensor init failed and the serial monitor printed "device not detected"?
      Check whether the I2C address in the codes is the same as the sensor address.
