Detecting obstacle with IR Sensor and Arduino Circuit Diagram About IR Obstacle Avoidance Sensor. The infrared (IR) obstacle sensor is used to detect the presence of any obstacle in front of the sensor module by using the infrared signal. The detection range is from 2cm to 30cm. The detection range can be adjusted by a built-in potentiometer. Pinout. IR obstacle avoidance sensor includes three pins: Thermal infrared sensor: It works by the changes of heat in its surrounding or uses infrared radiations as a heat source.; Photo infrared sensor: It uses a photo diode to detect infrared radiations.We will focus on this type of IR sensor. Several types of infrared obstacles avoidance sensor modules are available in the market but the one we will focus on in this article is the photo IR
An IR sensor is made up of two basic parts: an infrared LED and an infrared photodiode. The IR LED emits the infrared light while the IR photodiode converts the reflected LED light to an electrical current that allows the sensor to interpret the strength of the reflected IR. There are three header pins for the HW-201 obstacle sensor.

An infrared sensor is an electronic device that emits an infrared wave to sense objects in its surroundings. It is used in the obstacle avoidance systems in Robotics. Autonomous cars have a number of these sensors installed at various locations on the vehicle. WIRING Lesson 08: IR Obstacle Avoidance Sensor Module In this lesson, you'll learn how to use an Infrared obstacle avoidance sensor with an ESP32 Development Board. We'll explore how the sensor detects obstacles and alters its output signal. You'll also learn how to read these signals using the ESP32 and display them on the serial monitor.
IR sensors are used in applications ranging from basic obstacle detection to precise distance measurement. Types of IR Sensors # There are several types of IR sensors, each suited to different applications based on characteristics like range, output type, and sensitivity. Some common modules include: IR-O8H: A compact sensor module for simple โฃ In the field of obstacle detection, infrared sensors have become an essential tool โฃforโ a wide range of technical applications. These devices, based on infrared technology, are capable of effectively detecting the presence of objects and obstacles in their environment, allowing automated systems to avoid collisions or carry out predefined actions. In this project, we'll build a line-following robot with obstacle avoidance capabilities using an Arduino UNO. The robot uses two infrared (IR) sensors to detect and follow a line and an ultrasonic sensor to detect obstacles in its path. When an obstacle is detected within a certain distance, the robot stops to avoid collision.
