Descripción
Product Details:
WSP2110 semiconductor organic vapor sensor adopts advanced plane production technology to form heaters and metal oxide semiconductor gas-sensitive materials on micro Al2O3 ceramic substrates, which are led out by electrode leads and encapsulated in metal sockets and caps. When the detected gas is present, the higher the concentration of VOC gas in the air, the higher the conductivity of the gas sensor. A simple circuit can convert this conductivity change into an output signal corresponding to the gas concentration.
Features:
High sensitivity to toluene, benzene, formaldehyde and other organic gases
Small component size
5V constant voltage, low power consumption
Fast response and recovery characteristics
Simple drive circuit
Excellent stability and long service life
