Product details
Adopt high-quality double-panel design, with power indicator and TTL signal output indicator.
With DO switch signal (TTL) output and AO analog signal output
TTL output high and low level. (Can be directly connected to the microcontroller or relay module)
The analog output voltage changes with the concentration. Fast response feature.
Has long service life and stability. Electrical performance:
Input voltage: DC5V Power consumption (current): 150mA
DO output: TTL digital quantities 0 and 1 (0.1 and 5V)
AO output: analog level signal reminder: After the sensor is powered on, it needs to be preheated for about 20S, and the measured data is stable. It is normal for the sensor to heat up, because there is a heating wire inside, if it is hot, it will not be normal.
Wiring:
1. VCC: connect to the pole of the power supply (5V)
2. GND: connect to the negative pole of the power supply
3. DO: TTL switch signal output
4, AO: analog signal output
Colour:green
Material:Metal Package Contents:
1 x MQ139 Freon Sensor Module Only the above package content, other are not included.
Note: Light and different displays may cause the color of the item in the a little different from the real . The measurement allowed error is +/- 1-3cm.
