Recovery time: ≤30s (70% Response)
Heating resistance: 31Ω±3Ω
Heating Current: ≤180mA
Heating Voltage: 5V±0.2V
Heating Power: ≤900mW
detect Voltage: ≤15V
Ambient Temperature: -10℃ to 65℃,
Humidity: ≤95%RH
Storage conditions: Temperature:-20℃-70℃,Humidity:≤ 70%RH
Features:
Signal output instructions;
Dual signal output (analog output, and TTL level output);
TTL output valid signal is low, can be connected directly to the microcontroller;
0 ~ 5V analog 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
Package included:
1 x Alcohol module
