7, product dimensions: 35.5 (L) * 22.5 (W) * 23 (H)
8, with long service life and reliable stability
9, fast response to recovery features
Electrical performance:
Input voltage: DC5V Power consumption (current): 150mA
DO output: TTL digital 0 and 1 (0.1 and 3.3V)
AO output: 0.1-0.3V (relatively no pollution), the maximum concentration of about 4V voltage
Special reminder: the sensor power, the need to preheat 20S or so, the measured data was stable, the sensor fever is a normal phenomenon, because the internal electric wire, if the hot is not normal.
Wiring:
1, VCC: then the power supply positive (5V)
2, GND: Connect the power supply negative
3, DO: TTL switch signal output
4, AO: analog signal output
