2 cm to 30 cm (Subject to target reflectivity) Effective Detection Angle: ~35° field of view

The LM393 comparator compares the photodiode's voltage to the reference voltage set by the potentiometer.

If you’ve been hunting for the elusive "official" datasheet, you’ve probably noticed it's a bit like a ghost—everyone knows what it does, but the original manufacturer's document is hard to find. Here is the definitive breakdown of everything you need to know to master this sensor. 🛠️ Technical Specifications at a Glance

The is a low-cost infrared (IR) obstacle avoidance sensor module commonly used in robotics for short-range detection. It functions by emitting an IR signal from a transmitter LED; if an object is within range, the IR light reflects back and is detected by a receiver phototransistor, triggering a digital signal . Core Technical Specifications Specification Operating Voltage 3.0V – 6.0V DC Detection Range 2cm – 30cm (Adjustable via onboard potentiometer) Detection Angle Approximately 35° Current Consumption ~23 mA at 3.3V / ~43 mA at 5.0V Output Type

The module features a standard 3-pin male header for easy interfacing.
