hai kak. Mohon maaf untuk minimal order 20 ribu ya kak baru bisa kita proses, diluar ongkirSTOCK per 18 mei = 10 PCS

Sensor MQ-2 Introduction:

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