Air quality, temperature, pressure and humidity sensor CCS811+SI7021+BMP280 I2C

Product detailed description

Air quality, temperature, pressure and humidity sensor CCS811+SI7021+BMP280 I2C

The CCS811 is a low-voltage digital gas sensor that incorporates a MOX gas detector that can detect a wide range of VOCs for room air quality detection. There is also a microcontroller on the module that processes the data using an AD converter and communicates with the environment using the I2C bus.

Remark:

• This product is not a standalone functional unit and may require professional installation.
• Product images are for illustration purposes only and may sometimes differ from the actual appearance of the item. However, this does not change its basic properties.
• If a sensor on the module is not communicating, it is first necessary to check the correct setting of the I2C communication addresses! The I2C addresses listed in the description are valid for the series on which they were detected, it is possible that the manufacturer may change them at any time! To find out the exact current I2C addresses, we recommend using an I2C scanner.
