IR Sensor Module
- Product SKU: R0339
- Category: Arduino Ecosystem, Beginner Friendly, Best Sellers, ESP32 & NodeMCU Ecosystem, FEATURED PRODUCT COLLECTIONS, Quick Deliverables, Sensor Modules, Sensors, Sensors, Sensors, Under ₹100
The IR Sensor Module is designed with excellent adaptability to ambient light and features a pair of infrared transmitter and receiver tubes. The infrared emitter sends out a signal at a specific frequency, and when an object is detected (i.e., a reflective surface is encountered), the signal is reflected back to the receiver. After being processed by a comparator circuit, the green LED indicator lights up and a digital signal (low level) is output.
The module includes a potentiometer that allows you to adjust the detection range between 2 cm and 10 cm. It operates on a voltage range of 3.3V to 5V. With minimal interference and easy assembly, the sensor is user-friendly and versatile.
Applications include:-
-
Obstacle detection in robotics
-
Obstacle avoidance systems
-
Assembly line object counting
-
Black and white line tracking for line-following robots
Features of IR Sensor Module:-
- When the module detects obstacles in front of the signal, the circuit board green indicator light level, while the OUT port continuous output low-level signals, the module detects a distance of 2 ~ 10cm, detection angle 35 °, the detection distance can be potential adjustment with adjustment potentiometer clockwise, the increase in detection distance; counterclockwise adjustment potentiometer, the detection distance decreased.
- the sensor active infrared reflection detection, target reflectivity and shape of the detection distance of the key. The black minimum detection range, white maximum; small area object distance is small, a large area from the large.
- The sensor module output port OUT can be directly connected with the microcontroller IO port can also be driven directly to a 5V relay; Connection: VCC-VCC; GND-GND; OUT-IO.
- The comparator using LM393, stable.
- 3-5V DC power supply module can be used. When the power is turned on, the red power LED is lit.
- With the screw holes of 3mm, easy to install.
- Board size: 3.1CM * 1.5CM.
- Each module in the delivery has threshold comparator voltage adjustable via potentiometer, special circumstances, please do not adjust the potentiometer.
Interface(3-wire):-
- VCC external 3.3V-5V voltage (can be directly connected with the a 5v microcontroller and 3.3v microcontroller).
- GND external GND.
-
OUT board digital output interface (0 and 1).
