The PNUCLEOIKA02A1 expansion board interfaces electrochemical sensors with the MCU on the STM32 Nucleo development board. Electrochemical gas sensors help detect toxic gases like CO, SO. 2, NO and CL. 2. Specifically, the PNUCLEOIKA02A1 evaluation pack features the carbon monoxide sensor (Figaro TGS5141), which acts as a fuel cell.
Fig. 3 Typical Electrochemical Sensor Setup. 29 Chapter 2 Electrochemical Sensors first passes through a small capillarytype opening and then diffuses through a hydrophobic barrier, and eventually reaches the electrode surface. This approach is adopted to allow the proper amount of gas to react at the sensing electrode to produce a sufficient electrical signal while preventing the ...
A sensor supervision system for periodically providing a test to accesses the status of a gas detection sensor, such as a carbon monoxide (CO) sensor, is provided. To access the status of the CO sensor, a processor provides a voltage to the sensor supervision system, such that a voltage is applied to CO sensor, charging the CO sensor. The status of the CO sensor is accessed by determining the ...
Electrochemical sensors offer several advantages for instruments that detect or measure the concentration of many toxic gases. Most sensors are gas specific and have usable resolutions under one part per million (ppm) of gas concentration.
