BME680 Environmental Sensor with Arduino (Gas, Temperature, Humidity, Pressure)

RWF 25,000.00

BME680 is an environmental sensor that combines gas, pressure, humidity and temperature sensors. The gas sensor can detect a broad range of gases like volatile organic compounds (VOC).

Description

For this reason, the BME680 can be used in indoor air quality control.

BME680 Measurements

The BME680 is a 4-in-1 digital sensor that measures:

  • Temperature
  • Humidity
  • Barometric pressure
  • Gas: Volatile Organic Compounds (VOC) like ethanol and carbon monoxide

Relevant Information Regarding Gas Sensor

The gas sensor gives you a qualitative idea of VOCs gasses in the surrounding air. So, you can get trends, compare your results and see if the air quality is increasing or decreasing. To get precise measurements, you need to calibrate the sensor against knows sources and build a calibration curve.
