MQ-3 Alcohol Ethanol Gas

• High Sensitivity
• Stable and long life
• Detection Range: 10 - 1,000 ppm CO
• Response Time: <150s
• Heater Voltage: 5.0V

Characteristics:

1. Having a signal output instruction.
2. Dual signal output (analog output, and TTL level output).
3. TTL output valid signal is low. (Low-level signal when the output light can be directly connected to the microcontroller)
4. 0 ~ 5V analog output voltage, the higher the concentration the higher the voltage.
5. For ethanol vapor with high sensitivity and good selectivity.
6. Has a long life and reliable stability
7. Rapid response and recovery characteristics

Application:                       

• Vehicle alcohol detector
• Portable alcohol detector
• For field testing of motor vehicle drivers and other non-drinking and operating personnel, but also for other places ethanol vapor detection
