Sensor Board

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.
