Product Description
MQ-135 Air Quality Sensor Hazardous Gas Detection Module MQ135 sensor
Product Overview:
MQ135 gas sensor sensitive material used in the clean air, low conductivity tin oxide (SnO2). When present in the environment pollution gas sensor, conductivity sensor with the increase in air pollution in the gas concentration increases. Use simple circuit can convert the change in conductivity of the gas concentration corresponding to the output signal.
MQ135 ammonia gas sensor, sulfide, benzene vapor high sensitivity, smoke and other harmful monitoring will also be ideal. The sensor can detect a variety of harmful gases, it is a low-cost sensors for a variety of applications.
Application:
Can be used for home and factory gas leakage monitoring devices, suitable for liquefied petroleum gas, butane, propane, methane, smoke, etc.
Features:
Using 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
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 .
Wiring:
VCC: positive power supply (5V)
GND: power supply is negative
DO: TTL switching signal output
AO: analog signal output
NOTE:
After the sensor is powered, need to warm about 20S, measured data becomes stable, heat sensor is normal
