5CH IR SENSOR SWITCH 309874

Description

The HKD IR Sensor Switch Module (commonly utilized as a 4-pin IR Obstacle Avoidance Proximity Sensor) is an essential, highly adaptable electronic component designed for distance detection and automated switching. The module works by emitting a beam of infrared light via an IR LED; when an object crosses the path, the light reflects back to an onboard receiver. It features dual precision potentiometers that allow you to tune both the detection distance and sensitivity, making it perfect for custom robotics, automation fixtures, and touchless smart switches.Adjustable Detection Range: Easily tune the active sensing distance (typically 2cm to 30cm/80cm depending on the specific application environment) using the onboard trimmer potentiometers.4-Pin Interface Architecture: Outfitted with VCC, GND, Digital Output (OUT), and an Enable (EN) pin for advanced microcontroller integration and power cycling.Status Indicator LEDs: Dual onboard LEDs provide instant visual feedback—one for power verification and another that illuminates the exact moment an obstacle is detected.Ambient Light Resistance: Designed with specialized sensor shielding to reduce external interference from ambient room lighting or sunlight.Compatibility GuideThis module operates on standard low-voltage logic (3.3V to 5V DC), making it directly compatible with popular hobbyist microcontrollers and development ecosystems.CategoryCompatible Hardware & SystemsMicrocontrollersArduino boards (Uno, Nano, Mega, Pro Mini), ESP32, ESP8266 (NodeMCU), Raspberry Pi Pico, and STM32 architectures.Single Board ComputersRaspberry Pi models (3, 4, 5, Zero) via GPIO digital input pins (requires a Python script to monitor the OUT pin status).DIY Robotics & KitsSmart robot car chassis kits, line-following tracking platforms, automatic conveyor setups, and custom automated maze solvers.Smart Switches & Relays5V Relay Modules (to easily build touchless hand-wave switches, automatic trash cans, or proximity-based lighting alarms).💡 Wiring Tip:VCC: Connects to 3.3V–5V power.GND: Connects to system Ground.OUT: Connects directly to any digital input pin on your microcontroller. It outputs a LOW signal when an obstacle is detected and a HIGH signal when the path is clear.EN (Enable): Jumpered by default to keep the sensor permanently active. Remove the jumper if you want your microcontroller to toggle the sensor on and off programmatically.
