Detection
sing high-quality dual-panel design, with power indicator and TTL signal output instructions;
The switching signal having a DO (TTL) output and analog output AO ;
TTL output valid signal is low . ( Low-level signal when the output light can be directly connected to the microcontroller or relay module )
Analog output voltage with the higher concentration of higher voltage.
A gas, natural gas, city gas , smoke better sensitivity.
There are four screw holes for easy positioning ;
Has a long life and reliable stability
Rapid response and recovery characteristic
Input voltage : DC5V Power consumption ( current ): 150mA
DO output : TTL digital 0 and 1 ( 0.1 and 5V)
AO output :0.1-0 .3 V ( relative to pollution ) , the maximum concentration of a voltage of about 4V
Special note:
After the sensor is powered , needs to warm up around 20S, measured data was stable , heat sensor is a normal phenomenon , because the internal heating wire , if hot is not normal .
VCC: positive power supply (5V)
GND: power supply is negative
DO: TTL switching signal output
AO: analog signal output
Package included:
5 x MQ-5 LPG Gas City Sensor Module
Sensitive material MQ-5 gas sensor is used to clean the air in the lower conductivity
MQ-5 LPG Gas City Sensor Module
Applications : Liquefied petroleum gas, natural gas, coal gas monitoring device suitable for home or industrial. Excellent resistance to alcohol, smoke interference ability
This sensor can Fast response and recovery characteristics
TTL output signal is low. (When low output signal light, and can be connected directly to the microcontroller)
