MQ135 MQ-135 Sensor Air Quality sensor Hazardous Gas Detection Module Arduino
Module application:
The harmful gas detection device for family and environment is suitable for the detection of harmful gases such as ammonia, aromatic compounds, sulfide, benzene series steam, smoke and other gases, and the concentration range of gas sensing element is 10 1000ppm to
Module feature:
1, the use of high quality dual panel design, with power and TTL signal output indicator;
2, with DO switch signal (TTL) output and AO analog signal output;
3, TTL output signal is low level. (when the output is low, it can be directly connected to the microcontroller or relay module).
4, analog output voltage, the higher the concentration of higher voltage.
5, the air quality, harmful gas detection has better sensitivity.
6, four screw holes for positioning;
7, product appearance size: 32 (L) *20 (W) *22 (H)
8, has long service life and reliable stability
9, rapid response recovery characteristics
Electrical performance:
Input voltage: DC5V power (current): 150mA
DO output: TTL number 0 and 1 (0.1 and 5V)
AO output: 0.1-0.3V (relative no pollution), the highest concentration of about 4V
Special remind: sensor is energized, the need to preheat the 20s about, the measured data is stable, heat sensor belongs to the normal phenomenon.) because of the internal electric heating wire, if hot is not normal.
Connection mode:
1, VCC: power supply positive electrode (5V)
2, GND: power supply negative
3, DO:TTL switch signal output
4, AO: analog signal output
