2. DO signal (TTL) output and AO analog signal output;
3. TTL output high and low levels. (Can be directly connected to a single-chip microcomputer or relay module)
4. Analog output voltage changes with concentration.
5. There is a screw hole for easy positioning;
With long service life and reliable stability
Fast response recovery characteristics
Electrical performance:
Input voltage: DC5V Power consumption (current): 150mA
DO output: TTL digital quantity 0 and 1 (0.1 and 5V)
AO output: analog level signal
Special reminder: After the sensor is powered , it needs to be preheated for about 20S before the measured data is stable. It is normal for the sensor to heat because there is a heating wire inside. If it is hot, it is not normal.
Wiring method:
1. VCC: connected to the positive pole of the power supply (5V)
2. GND: connected to the negative pole of the power supply
3. DO: TTL signal output
4. AO: analog signal output
5. There are fixing bolt holes for easy installation
