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
