ماژول سنسور تشخیص گاز متان MQ-4

توضیحات کالا

ماژول سنسور تشخیص گاز متان / طبیعی MQ-4 Module application: for home or factory methane gas, natural gas and other monitoring devices, can be tested natural gas, methane 300 to 10000ppm; Module features: 1, high-quality dual-panel design, having a power indicator and a TTL signal output instruction; 2, having a DO Switching signal (TTL) output and AO analog signal output; 3, TTL output valid signal is low. (When the output low signal light, can be directly connected to the microcontroller or relay module) 4, the analog output voltage, the higher the higher the voltage the higher the voltage. 5, the methane, natural gas detection has a better sensitivity. 6, there are four screw holes to facilitate positioning; 7, product dimensions: 32 (L) * 20 (W) * 22 (H) 8, with long-term life and reliable stability 9, fast response recovery characteristics Electrical properties: 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 Note: sensor After power, need to preheat 20S or so, the measured data was stable, the sensor fever is a normal phenomenon, because the internal electric wire, if hot is not normal.
