This sensor builds on the photo-acoustic sensing principle.
Sensor board is equipped with an I2C interface.
Sensor support is available in HW 3.5+ and SW 1.50+.
When connecting via the I2C interface, select the option with this sensor on the I2C and 1Wire sensors page. As a result, the readings from the sensor will be available in the fields T1, H1, CO2.
