Product description: CCS811 + BME280 - Clean air, temperature, humidity and pressure sensor - I2C - DFRobot SEN0335
A multifunctional environmental sensor from DFRobot that incorporates two chips: CCS811, corresponding to the air quality sensor, and BME280, which is responsible for measuring temperature, humidity and pressure. The module communicates via the I2C interface bus. It is powered by a voltage in the range of 3.3 V to 5 V. The sensor is compatible with the Arduino microcontroller, and connection to it is enabled by solder fields, to which the goldpin connectors included in the kit should be soldered.
The sensor has leads in the form of solder fields, which enable connecting it with the controller module.
