The sensor board hosts four sensors which connects the sensors to the Robostix
ADC channels and IO pins for switching the sensors on/off.
The four sensors are:
- Acoustic sensor also known as a microphone
- Carbon dioxide sensor
- Carbon monoxide sensor
- Organic solvent vapour sensor (detects benzene, alcohol')
Figure 3.7 shows the sensor board with
its four sensors.
