MQ-5 Methane LPG Gas Sensor
- Indication of the signal output.
- Dual signal output (analog output, and TTL level output)
- TTL output signal is low. (When low output signal light, and can be connected directly to the microcontroller)
- 0 ~ 5V analog output voltage, the higher the concentration, the higher the voltage.
- Liquefied petroleum gas, natural gas, city gas, better sensitivity.
- Has a long life and reliable stability
- Fast response and recovery characteristics
- Operating voltage: DC 5 V
