1. Size: 32mm (length) * 22mm (width) * 27mm (height) 2. Weight: 7g 3. Main chip: LM393, MQ-5 gas sensor 4. Working voltage: DC 5 volts 5. Has a signal output indication. 6. Dual signal output (analog output AOUT and TTL level output DOUT) 7. TTL output valid signal is low level (when output low level, the signal light is on, it can be directly connected to the microcontroller) 8. Analog output 0-5V voltage, the higher the concentration, the higher the voltage 9. High sensitivity to butane, propane and methane 10. The reference concentration can be adjusted by the blue potentiometer. The reference concentration is reduced clockwise, counterclockwise rotation, reference thick Elevated 11. Has a long service life and reliable stability 12. Fast response recovery features
