This IR reflective sensor utilizes a TCRT to detect color and distance. It emits IR and then detects if it receives the echo. This sensor is often used in line. The TCRT are reflective sensors which include an infrared emitter and to sense the presence of an ob-ject by using the reflective IR beam from the object. The TCRT and TCRTL are reflective sensors which include IR – diode PACKAGE DIMENSIONS in millimeters, TCRT 1.

If we only have to detect the presence of an object then the sensor will be used as digital sensor if the distance of the object should also has to be measured then the sensor is used as a analog sensor. One major drawback of such IR sensors is that they easily get affected by environmental conditions.

The TCRT sensor is just a combination of a photodiode and a photo transistor. You must have JavaScript enabled in your browser to utilize the functionality of this website. Like the photo transistor will not only react to the IR light from the photo diode but will also react to the IR light from Sunlight, house lightings and other commonly available sources.

Emulator and Debugger for MSP This means that it can only read the wavelength it emits, allowing it to identify reflective surfaces without interference from outside sources like sunlight.

TCRT IR Sensor Pinout, Equivalent, Circuit & Datasheet

My Cart – 0 item. You must have JavaScript enabled in your browser to utilize the functionality of this website. There is also an on-board potentiometer to adjust the sensitivity. Applications Commonly used in proximity detection applications Line follower or maze solver robots Distinguish between reflective and non-reflective surface Obstacle detection and avoidance 2D-Model.


The measuring distance range from 1mm to 8mm, and the central point is about 2.

IR Reflective Sensor – TCRT5000

The photo diode is powered through a current limiting resistor of value R and the Transistor is also grounded through a 10K resistor as shown in the below picture. Adjustable Infrared Sensor Switch 3 – fcrt5000.

In such scenarios, the circuit could turn on when it identifies a card with a reflective strip, or could limit automation when a reflective surface is identified.

But the distance can only be calculated for short range objects and is also if o environmental disturbance.

My Cart – 0 item. This sensor is often used in line following robots, auto data logging or utility meters, because this module can sense if a surface is white or black. The package includes two mounting clips.

TCRT IR Sensor | Infrared Reflective Surface Sensor

Welcome to Elecrow Online Store. It has both a Photodiode and a Phototransistor coupled in its package.

TCRT sensor works with the general infrared sensor, like a sense of a TCRT has an infrared emission tube and tcrt5000 infrared receiver tube. However, these Electronic Sensors are becoming far more accessible in modern times, and Makers have been using them for a wide range of applications, such as: Adjustable Infrared Sensor Switch 3 – 80cm. So if you look for a sensor to measure distance of an object in front of it you should try the HC-SR04 Ultrasonic sensor. It emits IR and then detects if tcrr5000 receives the echo.


Please, log in or register. When the infrared emission tube by the receiver to receive the reflected tube, the receiver tube resistance will changeThe circuit is generally reflected in the tcrt500 of voltage changes, and after the ADC conversion or LM circuit shaping and other processed output results.

Our price is lower than the manufacturer’s “minimum advertised price. Similarly the Photo jr also has two pins Collector and Emitter which can be used to read the IR signal that is reflected back.

The transistor does not have a base pin because the biasing of the transistor is controlled by the amount of IR light it receives. You have no obligation to purchase the product once you know the price. Other than that this sensor is perfect for detecting the proximity of an object in front of it. Tiny Adjustable Infrared Sensor Switch 3 – cm. With such a small form factor, this component can be installed into almost any system, and can be used in a wide range of different ways.
