Specification: Origin: Mainland China Output: Switching Transducer Type: Optical-Electronics Sensor Tracing Sensor Trolley Tracing Module TCRT5000 Infrared Reflective Photoelectric Switch Product parameters: 1.Use TCRT5000 infrared reflection sensor 2.detection reflection distance: 1mm - 25mm applicable 3.Comparator output, clean signal, good waveform, strong driving ability, more than 15mA. 4.with potentiometer to adjust the sensitivity 5.Working voltage 3.3V-5V 6.Output form : digital switch output (0 and 1) 7.With fixing bolt hole, easy to install 8.Use wide voltage LM393 comparator Product size: 35*15*12mm Product use: 1.Electricity meter pulse data sampling 2.fax machine shredder paper detection 3.Obstacle detection 4. black and white line detection Function TCRT5000 sensor infrared transmitting two tubes constantly emit infrared, when the emitted infrared is not reflected back or reflected back but the intensity is not large enough, infrared receiving tube has been in the off state, at this time the output of the module is high, indicating that the two tubes have been in the off state; detected objects appear in the detection range, infrared is reflected back and the intensity is large enough, infrared receiving tube saturated, the output of the module is low, indicating that the second tube is lit. Wiring methods: 1.VCC: connected to the power supply positive (3-5V) 2.GND: connected to the negative power supply 3. DO: TTL switch signal output 4.AO: analog signal output (different distance output different voltage, this pin can generally not be connected) Note: Due to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures. Thank you! Please allow 1-2cm measuring deviation due to manual measurement. 1Pc*Infrared Reflectance Sensor [relateproductdetail/]
