•Main chip: LM393, MQ-3 gas sensor.
•Operating voltage: DC 3-5V.
•with the signal output indication.
•the dual signal output (analog output, and TTL level output).
•TTL output valid signal is low level, can connected to microcontroller directly.
•0 ~ 5V analog output voltage, the higher concentration the higher voltage.
•with high sensitivity and good selectivity for ethanol vapor.
•with a long service life and reliable stability.
•rapid response and recovery characteristics.
•size: 32mm*22mm*22mm(L * W * H)
Application:
•For motor vehicle drivers and the other non-drinking workers on-site inspection, also for other places of ethanol vapor detection, alcohol detection range: 10 ~ 1000ppm
