MP-4 Combustible Gas Detection Sensor Module – Analog Output, Wide-Gas Compatibility

Description

MP-4 Combustible Gas Detection Sensor Module
Description

• MP – 4 combustible gas sensors using multilayer thick film manufacture process, in miniature

• Al2O3Both sides of the ceramic substrate respectively make heater and MOS Gas
• Sensitive layer, encapsulated within the metal shell. When the environment have tested gas in the air

• Presence of sensor conductivity changes.Of the higher concentrations of the gas sensor

• The higher the conductivity.Using simple circuit can be this kind of electrical conductivity

• With gas concentration change into the corresponding output signal.

Characteristics:
This product in a wider range of concentration of methane has a good sensitivity, with strong anti-interference ability, low power consumption, fast response recovery, stabilityGood, long life, low cost, simple drive circuit etc.
Application
1. Used in homes, factories, commercial use of the combustible gas leakage monitoring devices, fire/safety detection system.2. Combustible gas leakage alarm system, gas leak detector.

Description:
MP135 gas sensor is for air quality. It adopts multilayer thick film manufacturing technology. The heater and metal oxide semiconductor material on the ceramic substrate of subminiature Al2O3 are fetched out by electrode down-lead, encapsulated in metal socket and cap. Conductivity of the sensor is affected by the concentration of target gas. The higher the concentration is, the higher conductivity of sensor gets. Users can adopt simple circuit to convert variation of conductivity into output signal corresponding to gas
concentration.
