Pu Sheng Supply Dart WZ Formaldehyde Gas Sensor DART Long Life Formaldehyde Detection Module

Product Description

The WZ type formaldehyde gas sensor is a product of the world's top formaldehyde sensor manufacturer, Dat Company. The sensor is based on the principle of micro fuel cells for detection. When formaldehyde gas is present in the environment, gas molecules quickly reach the core detection unit of the sensor through natural diffusion and concentration polarization, and undergo oxidation reaction at the positive electrode. Oxygen in the environment undergoes reduction reaction at the negative electrode of the sensor, forming a closed-loop reaction. The generated current is proportional to the concentration of formaldehyde gas in the environment. The size of the detected current can accurately quantify the formaldehyde gas content in the environment. This sensor is a passive device that does not require any external excitation during the reaction process, with zero power consumption. It is very suitable for portable instruments and places that require battery power supply.
Features: 0 power consumption - high precision - high sensitivity - high cost-effectiveness - wide linear range - fast response speed - excellent repeatability and stability
Typical applications: smart home - smartphones - wearable devices - smart buildings - smart city environmental protection - industrial safety environment - fire safety field
