Excellent for teaching kids robotics
Bought this for a weekend workshop with my kids. The wiring is straightforward, and the built-in LEDs help visualize when the sensor detects an object or line. Highly recommended for beginners.

Works well with Raspberry Pi GPIO
Connected this directly to my Raspberry Pi GPIO pins without any issues. The digital output is clean. Only giving 4 stars because the included pins were a bit loose, but easily fixed with soldering.

Perfect for my Arduino robot project
This sensor module works exactly as described. The sensitivity adjustment via the potentiometer makes it very easy to calibrate for different floor surfaces. I used two of these for a line-following car, and the response time is excellent.

Reliable and durable
I have been using TELESKY modules in several prototypes. They are robust and handle minor bumps well. The detection range is accurate within the specified limits, making them ideal for smart car applications.

Fast shipping and great performance
Arrived quickly and was well-packaged. Tested it immediately on a black tape line, and the contrast detection was instant. No lag in the signal output. Will definitely buy more for future projects.

Good value but needs careful calibration
Great little sensor for the price. It took me a while to get the distance settings right for obstacle avoidance, but once calibrated, it performs consistently. Just make sure your power supply is stable.
Q: Is this compatible with 3.3V logic systems like ESP32?
A: Yes, the module operates on a voltage range of 3.3V to 5V, making it fully compatible with 3.3V logic systems such as the ESP32 and Raspberry Pi without needing a level shifter.
Q: How do I adjust the detection distance?
A: There is a blue potentiometer on the board. Use a small screwdriver to turn it clockwise to increase sensitivity (longer distance) or counter-clockwise to decrease it. Test with your specific target object while adjusting.
Q: Does this come with jumper wires?
A: The package typically includes the sensor module and a set of header pins that you may need to solder yourself. Jumper wires are usually sold separately, but check your specific order details.
Q: What is the maximum current draw for this module?
A: The typical current consumption is around 20mA when the IR LED is active. Please ensure your microcontroller pin or external power source can supply at least 30mA to be safe.
Q: Can this sensor detect clear glass obstacles?
A: Infrared sensors generally struggle with transparent objects like clear glass because the IR light passes through rather than reflecting back. It is best suited for opaque obstacles or contrasting lines.
