Description:
---> The main chip: LM393, MQ-3 gas sensor
---> Operating voltage: DC3-5V
---> Response time: ≤10s (70% Response)
---> Recovery time: ≤30s (70% Response)
---> Heating resistance: 31Ω±3Ω
---> Heating Current: ≤180mA
---> Heating Voltage: 5V±0.2V
---> Heating Power: ≤900mW
---> Detect Voltage: ≤15V
---> ******t Temperature: -10℃ to 65℃,
---> Humidity: ≤95%RH
---> Storage conditions: Temperature:-20℃-70℃,Humidity:≤ 70%RH

Features:
---> Signal output instructions;
---> Dual signal output (****og output, and TTL level output);
---> TTL output valid signal is low, can be connected directly to the microcontroller;
---> 0 ~ 5V ****og output voltage, the higher the concentration the higher the voltage;
---> Has a high sensitivity and good selectivity to ethanol vapor;
---> Has a long life and reliable stability;
---> Rapid response recovery characteristics;

Applications:
---> For motor vehicle drivers and other non-drinking and operating personnel on-site testing, also used in other places of ethanol vapor detection, detection of alcohol: detection range of 10 to 1000ppm
