Sell 【et】 New MQ135 Air Quality Sensor Hazardous Gas Detection Module For Arduino MQ-135 . best price

Features: 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.
