Product Descrption:
	
Main Chip: LM393, ZYMQ-5 gas sensor
	
Operating Voltage: DC 5V
	
Input Voltage: DC5V
	
Power: 150mA
	
DO Output: 0.1V/5V
	
AO Output: 0.1-0.3A
	
Features:
	
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
