Detail HQ Module MQ-4 natural gas, methane gas

hai kak. Mohon maaf untuk minimal order 20 ribu ya kak baru bisa kita proses, diluar ongkirstock per 9 mei = 25 pcs

MQ-4 sensor Introduction:
MQ-sensitive material 4 gas sensors used in 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-4 Methane gas sensor of
high sensitivity, propane, butane and has a good sensitivity. The sensor can
detect a variety of combustible gases, especially natural gas, it is a low-cost
sensor suitable for a variety of applications.

Module Applications:



For home or factory methane gas, natural gas and other monitoring devices, can
be tested natural gas, methane 300 to 10000ppm;
Module Features:
1, using high-quality dual-panel design, with power indicator and a TTL signal
output instructions;
2, with DO switching signal ( TTL) output AO analog signal output;
3, the TTL output valid signal is low. (When the output low signal light can be
directly connected microcontroller or relay modules)
4, the higher the higher the voltage, the voltage concentration analog output.
5, methane, natural gas has a good detection sensitivity.
6, there are four screw holes for easy positioning;
7, Product Dimensions: 32 (L) * 20 (the W) * 22 (H)
. 8, has a long life and reliable stability
9, rapid response recovery characteristics

Electrical performance: Input voltage: DC5V power (current): 150mA the DO
output: TTL digital 0 and 1 (0.1 and 5V)

AO Output: 0.1-0.3V (relatively clean), the highest concentration of about 4V
voltage Special note: Sensors Power, the need to warm about 20S, measured dat
