LPG-PROPANE-HYDROGEN GAS SENSOR MODULE MQ-2

රු440.00

Gas sensor module LPG-propane-hydrogen
Using the 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 the 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
