SunFounder MQ-2 Gas Sensor Module for Arduino and Raspberry Pi

10,99 (as of diciembre 13, 2017, 16:10)

An MQ-2 gas sensor module that outputs an analog value when sensing combustible gas. The higher concentration of the gas is, the greater value it will output. When the value exceeds the threshold set, the signal indicator will light up.
High sensitivity to liquefied gas, natural gas, town gas, smog, etc.
With a comparator LM393 to output both digital and analog signals at the same time

Usually ships in 24 hours
