Revolutionize Robotics with the Scienticy LM393 IR Obstacle Avoidance Sensor
Take your automation and robotics projects to the next level with the Scienticy LM393 IR Infrared Obstacle Avoidance Sensor Module. This module is a high-precision, reliable solution designed to detect objects in a robot’s path, making it an essential component for smart cars, obstacle-avoiding robots, and industrial counting systems.
Engineered with a premium Infrared (IR) Emitter and Receiver pair, this sensor works by emitting IR light and measuring the reflection from nearby objects. The onboard LM393 Voltage Comparator IC ensures a stable, noise-free digital signal, allowing your microcontroller to react instantly to obstacles. With its wide 3.3V to 5V DC operating range, it is perfectly compatible with Arduino, Raspberry Pi, ESP32, and ESP8266.
Key Features & Benefits
- Precision Detection: Optimized for accurate obstacle sensing with a 35° detection angle.
- Adjustable Sensing Range: Features a built-in multi-turn potentiometer to easily tune the detection distance from 2cm to 30cm.
- Stable Digital Output: Utilizes the LM393 IC for a clean digital waveform and strong driving capability (>15mA).
- Real-time Feedback: Equipped with dual onboard LEDs—Power Indicator (Red) and Obstacle Status (Green)—for effortless debugging.
- Plug-and-Play Design: Simple 3-pin interface (VCC, GND, OUT) for quick connection to breadboards or Arduino shields.
- Compact & Mountable: Small form factor with a 3mm fixed screw hole for secure installation in robot chassis or project boxes.
- Low Power Consumption: Efficiently operates on low current, making it ideal for battery-powered portable projects.
