- Size: 32mm X 22mm X17mm
- The main chip: LM393, MQ-6 gas sensors
- Operating voltage: DC 5 V
- Has a signal output indication.
- Dual signal output (analog output, and TTL level output)
- TTL output valid signal is low. (Low-level signal when the output light can be directly connected to the microcontroller)
- 0 ~ 5V analog output voltage, the higher the concentration the higher the voltage.
- For LPG, butane, propane has a good sensitivity.
- Having a long life and reliable stability
- Quick response and resume
