## Description

The infrared obstacle sensor is a compact IR proximity module designed for robotics and automation projects. It detects obstacles within a 2–40 cm range and outputs a TTL-level signal, making it easy to integrate with Arduino and other microcontrollers. The detection distance is adjustable via a multi-turn potentiometer, and the sensor features an enable pin for programmatic control. Operating on 3.3–5V, it's compatible with both 3.3V and 5V logic systems. Key Features Adjustable Detection Range – 2–40 cm, tuneable via multi-turn potentiometer TTL Output – Low when obstacle detected, high when clear Wide Voltage Range – Works with 3.3V and 5V systems Enable Pin – Programmatically enable or disable the sensor 35° Effective Angle – Focused detection cone for precise obstacle sensing Compact Size – 28 × 23 mm Specifications Interface – 4-wire (GND / VCC / Signal / Enable) Working Voltage – DC 3.3–5V Working Current – ≥ 20mA Detection Distance – 2–40 cm Effective Angle – 35° Operating Temperature – -10°C to +50°C Board Size – 28 × 23 mm Pinout + – Power (3.3–5V) GND – Ground OUT – Signal output (TTL) EN – Enable pin Example Code ⚡ Arduino void setup() { Serial.begin(9600); pinMode(9, INPUT); // Sensor output pin } void loop() { Serial.print("Sensor: "); Serial.println(digitalRead(9)); delay(500); } Ideal For Robot obstacle avoidance Proximity detection systems Automated line-following or maze-solving robots Arduino and microcontroller beginner projects Package Contents 1× Infrared obstacle sensor
