Features:
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
