IDUINO for maker’s life

Description:

MQ-2 gas sensor sensitive material used in the clean air low conductivity tin oxide
(SnO2). When there is the environment in which the combustible gas sensor,
conductivity sensor with increasing concentration of combustible gases in air
increases. Using a simple circuit to convert the change in conductivity of the gas
concentration corresponding to the output signal. MQ-2 gas sensor high on gas,
propane, hydrogen sensitivity of detection of natural gas and other flammable vapors
are also very good. This sensor can detect a variety of flammable gas, is a low-cost
sensors for a variety of applications.

Specification

 Power supply needs: 5V

 A gas, natural gas, city gas, smoke better sensitivity.
 There are four screw holes for easy positioning ;
 Has a long life and reliable stability
 Rapid response and recovery characteristics
 DO output: TTL digital 0 and 1 (0.1 and 5V)
 Detectable concentration: 300-10000ppm
