TCRT5000 IR Sensor : Pin Configuration & Its Applications

• TCRT5000 is an IR sensor. It is used to detect color and distance. This IR sensor is often used in line-following robots, auto data logging on utility meters, etc. This sensor can sense if a surface is white or black.
• The measuring distance range from 1mm to 8mm, and the central point is about 2.5mm. There is also an onboard potentiometer to adjust the sensitivity. The infrared diode will emit the infrared continuously when the module connects to the power, when the emitted infrared light has not been reflected or the strength is not big enough, the module will be in the off state, at this time, D0 output logic HIGH and the signal indicate LED off.

Pinout of TCRT5000 IR Sensor

• Anode: This is a positive pin of the infrared transmitter IR transmitter (Photo Diode).
• Cathode : This is a negative pin of the infrared transmitter IR transmitter (Photo Diode).
• Collector: This is the collector terminal of the IR receiver (Photo Transistor).
• Emitter: This is the emitter terminal of the IR receiver (Photo Transistor).

How to use the TCRT5000 IR Sensor

• The construction of the TCRT5000 IR Sensor includes an infrared emitter and phototransistor in a package that blocks visible light. The package includes two mounting clips. In this sensor, the emitting-light source and the detector are arranged in the same direction to sense the presence of an object, by using the reflective IR beam from the object. The sensor also consists of a phototransistor.
• In TCRT5000 IR Sensor, the infrared diode emits the infrared continuously when the module is connected to the power but when the emitted infrared light has not been reflected or the strength is not big enough, the diode will be in the off state. At this time, the output logic is LOW and the signal indicates LED off.
