Description Electrical performance: Input voltage: DC5V power consumption (current): 150mA DO Output: TTL digital 0 and 1 (0.1 and 5V) 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 الحالة جديد النوع أجهزة أخرى
