Sell MQ 135 Air Detection Module Home For Arduino best price

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, and other harmful gases. Has a long service life and reliable stability. Rapid response and recovery characteristics. Main chip: LM393, MQ-135 gas sensor Operating voltage: DC 5V Size:32mm X20mm X23mm(L * W * H) Color: blue Some Application: A hazardous gas detection apparatus for the family, the environment. Suitable for ammonia, aromatic compounds, sulfur, benzene vapor, and other gases harmful gas detection. Gas-sensitive element test concentration range: 10 to 1000ppm Package Included: 1 x MQ-135 Air Quality Hazardous Gas Detection Module #Gas #Detection #Module #Arduino #propane #MQ-135 #i-butane #Methane #Alcohol #Hydrogen #CO #Carbon #Monoxide #Sensor #gas #sensor #co #detector
