water vapor sensor TGS 2180
---detection for automatic control of microwave ovens

Description:
The TGS 2180 has relatively high sensitivity to water vapor and low sensitivity to organic vapors which may be generated from cooking food. The sensor's conductivity increases depending on absolute humidity. A simple electrical circuit can convert the change in conductivity to an output signal which corresponds to absolute humidity

Specifications:
1) Target gases : Water vapor
2) range：1 ~ 150g/m3
3) sensitivity (change ratio of Rs) : 0.77 ~ 0.92
4) Circuit Voltage：5.0±0.2V DC
5) Heater Voltage：5.0±0.2V DC

Features:
1) Low power consumption
2) High sensitivity to water vapor
3) High temperature durability
4) Long life and low cost
5) Uses simple electrical circuit
6) Small size]

Application:
Automatic cooking control in microwave ovens
