MQ-5 Natural Gas Sensor LPG METHANE BUTHANE MQ5

Sensor Gas untuk beraneka ragam gas (sulfida benzena uap asap atau gas-gas lainnya yang tidak sehat). Kepekaan dari 10 to 1000ppm. Main chip: LM393,MQ-135 gas sensor Operating voltage: DC 5V With signal output indicator instructions. Dual signal output (analog output, and TTL level output). TTL output valid signal is low level, (output low signal light, which can be accessed microcontroller IO port). Analog output with increasing concentration, the higher the concentration, the higher the voltage. with high sensitivity and good selectivity for Sulfide, benzene Department of steam, smoke and other harmful gases. Has a long service life and reliable stability. Rapid response and recovery characteristics. Size:36mm X24mm X25mm FEATURES * High sensitivity to LPG, natural gas , town gas *Small sensitivity to alcohol, smoke. * Fast response . * Stable and long life * Simple drive circuit APPLICATION They are used in gas leakage detecting equipments in family and industry, are suitable for detecting of LPG, natural gas , town gas, avoid the noise of alcohol and cooking fumes and cigarette smoke.
