Reliable and consistent readings
I bought three of these for a line-following robot upgrade. All three performed identically with no calibration drift over two weeks of testing. The build quality feels solid.

Best IR sensor in this price range
I have tried several brands, and this Genuine GP2Y0E03 module offers the best stability. The digital output saves a lot of processing time compared to analog sensors. Will buy again.

Good value, easy to integrate
Great little sensor for the price. Integration was straightforward using existing libraries. Only giving 4 stars because the wiring diagram on the package was a bit faint, but online resources helped.

Works well but sensitive to sunlight
The sensor is great indoors, but I noticed some noise in the readings when used near a window with direct sunlight. Once shielded, it worked perfectly. Just something to keep in mind for outdoor use.

Excellent for university projects
Used this for my final year embedded systems project. It provided the precision needed for our automated sorting mechanism. Delivery from Youxin Electronics was also very fast.

Perfect for my Arduino robot project
This sensor works flawlessly with my Arduino Uno. The I2C communication is stable, and the range detection is very accurate within the specified 4-50cm limits. Highly recommended for hobbyists.
Q: What is the minimum object size it can detect?
A: While the range is 4-50cm, the object should ideally be at least 1cm x 1cm with a reflective surface for reliable detection at the closer end of the spectrum.
Q: Does this come with connecting wires?
A: The module typically comes with header pins soldered or unsoldered depending on the specific batch option selected, but jumper wires are not included in the package.
Q: Is there a library available for ESP32?
A: Yes, there are several open-source libraries available on GitHub and the Arduino Library Manager that support the GP2Y0E03 for ESP32 microcontrollers.
Q: Can I use this to measure liquid levels in a tank?
A: Yes, it can be used for non-contact liquid level sensing provided the liquid surface is relatively calm and the sensor is mounted above the maximum fill line within the 50cm range.
Q: Is this sensor compatible with Raspberry Pi?
A: Yes, the GP2Y0E03 uses an I2C interface which is fully compatible with Raspberry Pi models. You just need to enable the I2C port in your configuration settings.
