Features :

• High sensitivity to combustible gases over a wide range

• Excellent detection for Propane, Butane, and LPG

• Long lifespan with low cost

• Simple driving circuit design

• Signal output indication available

• Dual signal output: analog and TTL level

• TTL output remains low; the low output signal light can connect directly to a microcontroller

• Analog output range: 0 ~ 5V — higher gas concentration results in higher voltage

• High sensitivity to hydrogen

• Resistant to interference from ethanol vapor, LPG (petroleum), and smoke

• Reliable stability and long operational life

• Fast response and quick recovery characteristics
