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.
