Product Name: keyes MQ-5 MQ5 Octopus Smoke Gas Sensor

Brief Description: 
dimension: 32mm X 22mm X height 27mm width 
the main chip: LM393, ZYMQ-5 gas sensor 
the working voltage: DC 5 V 
1, having a signal output instruction. 
2, dual signal output (analog output, and TTL level output) 
3, TTL output valid signal is low. (Low-level signal when the output light can be directly connected to the microcontroller) 
4, 0 ~ 5V analog output voltage, the higher the concentration the higher the voltage. 
5 of liquefied petroleum gas, natural gas, city gas has better sensitivity. 
6, has a long life and reliable stability 
7, rapid response and recovery characteristics 
Suitable for home or industrial liquefied petroleum gas, natural gas, coal gas monitoring devices. Excellent resistance to alcohol and smoke !

Brief Description:

dimension: 32mm X 22mm X height 27mm width

the main chip: LM393, ZYMQ-5 gas sensor

the working voltage: DC 5 V


1, having a signal output instruction.
