Sensor PCB – The sensor board acts as a sensor breakout board enabling users to inset any MiniPID photoionisation detection sensors and perform basic sensor testing. It can also be connected to the integration board making it really simple to add PID sensors to any application.

Integration PCB – The integration board provides signal processing, data logging and communications with industry standard 4-20 mA and Modbus outputs. It can be configured to switch a relay on at a given VOC concentration. The Integration board is configured with a simple PC application.
