                  Description:
                   
                  1. Size: 32mm x 22mm x 22mm
                  2. The main chip: LM393, MQ-3 gas sensor
                  3. Work voltage: DC3-5V
                  4. With the signal output instructions;
                  5. Dual output (analog output, and TTL level output);
                  6. TTL output valid signal is low, the microcontroller can be connected directly;
                  7. 0 ~ 5V analog output voltage, the higher the voltage the higher the concentration;
                  8. The ethanol vapor with high sensitivity and good selectivity;
                   
                  Application:
                   
                  For motor vehicle drivers and other non-drink operations of on-site inspection, but also for other places of ethanol vapor detection, detection of alcohol range: detection range of 10 ~ 1000ppm;

                  Package includes:

                  1 x Gas sensor module
