Connected Plant Sensor -TCRT5000 Infrared Reflector Track Photoelectric Sensor Module Highlights generic brand TCRT5000 Infrared Reflector Track Photoelectric Sensor Module Description: Scope of use: 1, power meter pulse data sampling. 2, fax paper machine paper detection3, barrier detection4, black and white line detectionModule. Features: 1. Using TCRT5000 infrared reflection sensor. 2. Detection distance: 1mm~25mm applicable, the focusing distance of 25mm. 3. The comparator output, the signal clean, good waveform, drive capability, more than 15mA. With multi-turn adjustable precision potentiometer sensitivity adjustment. The working voltage of 3.3V-5V. The output form: digital switching output (0 and 1). With a fixed bolt hole, easy to install. Small PCB size: 3.2cm x 1.4cm. Wiring: 1.VCC: connect the positive pole of the power supply (3-5V). 2, GND: connected to the negative power supply. 3, DO: TTL switching signal output 4, AO: analog signal output (different distance output different voltage, this foot generally can not be connected). Using wide voltage LM393 comparator Module features: TCRT5000 sensor infrared emitting diodes keep throwing infrared, when the infrared ray emitted is not reflected or reflected but the intensity is not large enough , the photosensitive transistor has been in the off state, then the module output is high, indicating that the diode has been in the off state. Specification: Material: Metal Size: 33 x 14mm / 1.30 x 0.55inch Package Include: 1 Piece TCRT5000 Infrared Reflector Light Barrier Line Track Sensor Module
