API for the MICS-VZ89 Gas Sensor. More...

Detailed Description

The MiCS-VZ-86/89 combines state-of-the-art MOS sensor technology with intelligent detection algorithms to monitor VOCs and CO2 equivalent variations in confined spaces.

The MICSV89 comes in 4 variants, PWM and I2C in 3.3 volts and 5 volts. This library only implements the I2c version of the device.

Device output is not valid until a warm up of 15 minutes of operation.
