Introduction to Carbon Monoxide Sensors?

Carbon monoxide sensors belong to chemical sensors. Chemical sensors mainly consist of two parts: conduction and conversion systems. CO gas detection sensor based on carbon monoxide gas detection. It can detect the concentration of hazardous gas CO exposed to the environment and clearly read the gas concentration, peak value, and high/low concentration alarm levels. If the current gas concentration values exceed the preset limit, an alarm will alert the user through sound and light.

What is an electrochemical gas sensor?

The biggest feature of electrochemical gas sensors is that the current is directly proportional to the concentration of carbon monoxide, and the output signal has a good linear relationship with the gas concentration, making signal processing and display very convenient. Another characteristic is that, as it is a room temperature reaction, a heater is not required. Therefore, the electrode voltage can be obtained using dry batteries, without the need for mains power, and it is also convenient for portable carbon monoxide detectors. Advantages: Small size, zero power consumption, high sensitivity, good stability, good linearity, good repeatability, fast impact speed, resolution can generally reach 1ppm, long lifespan. Disadvantages: There are significant differences in price, performance, craftsmanship, anti-interference performance, and susceptibility to temperature and humidity changes among different brands.
