Stack Emission Monitoring Electrochemical Sensors. The 3 Series (CO, SO 2, NO 2 and NO) are designed for stack emission monitoring. They can be used in the environment with those high concentration gases for a long time. The sensor electrodes are much bigger and deposited with thicker chemical compounds. The electrolyte used in the 3 Series Gas Sensors can sustain tougher …
Building a CO (carbon monoxide) detector that can alert you to dangerous levels of CO can be done with as little as a gas sensor, an Arduino (or other microcontroller) and some resistors. Adding a few op-amps can boost the sensitivity to measure the amount of CO present in the environment. Expanding on this knowledge, you can build your own air quality monitoring station, and compare your own ...
