MQ-2 smoke sensor module / gas sensor (with analog quantity and TTL low level NPN output)
First, size: X22mm X27mm 32mm long X wide X high
Two, the main chip: ZYMQ-2, LM393 gas sensor
Three, working voltage: DC 5 volts
Four, characteristics:
1, with signal output instructions.
2, dual signal output (analog output and TTL level output)
3, TTL output valid signal is low. (when the output is low, the signal light is bright, can be directly connected to the MCU)
4, analog output 0~5V voltage, the higher the concentration, the higher the voltage.
5, to the liquefied gas, natural gas, city gas, smoke has better sensitivity.
6, has a long life and reliable stability
7, fast response recovery characteristics
Five, application:
Gas leakage monitoring device suitable for home or factory, which is suitable for monitoring devices such as liquefied gas, methane, propane, methane, alcohol, hydrogen gas, smoke and so on.
