Description
Description:The LED pin must be adjusted into the cycle of 1 msLed seem to be using the PNP transistor to electricity, LED pin must receive a lower voltage.Commonly used system of air purifierAn infrared light-emitting diode and phototransistor, diagonal decorate allows it to dust in the air, the reflected light is detectedThe sensor has a very low current consumption (maximum 20 ma, ma 11 typical), can carry up to 7 VDC sensor. The output is an analog voltage is proportional to the measured by the dust concentration, sensitivity of 0.5 V / 0.1 mg/m3Attetion:You need to add a 150 ohm resistor and a 220 uf capacitance to use it.Power supply voltage: 5-7VWorking temperature: – 10-65 degrees CelsiusAccuracy: 0.5V/(0.1mg/m3)Dimension: 46 x 30 x 17.6 mm1x Ultrasonic Distance Measuring Transducer Sensor
