Good value but needs calibration

Great little sensor for the price. It took a few minutes to calibrate the threshold correctly, but once set up, it has been very reliable for my automated gate project.

Works well indoors only

The sensor performs great inside my workshop, but direct sunlight interferes with the reading significantly. Make sure to shield it if using outdoors.

Fast response time

I needed a sensor with low latency for a high-speed counting application, and this module delivers. The digital output is crisp and noise-free.

5 FAQ

Q: Does this come with a library for Arduino?

A: While we do not provide a proprietary library, the module uses a standard digital interface, making it compatible with thousands of existing open-source Arduino libraries for distance and obstacle detection.

Q: Can this module be directly connected to a 5V Raspberry Pi GPIO pin?

A: Yes, the module operates on 3.3V to 5V. However, ensure you configure the GPIO correctly in your software to read the digital signal.

Q: Can I use multiple sensors on one I2C bus?

A: No, this specific model outputs a digital TTL signal via a single pin, not I2C. To use multiple sensors, you will need to assign a separate digital input pin on your microcontroller for each module.

Q: Is the laser class safe for eyes?

A: This module uses a Class 2 laser diode. While generally safe for brief accidental exposure, you should avoid staring directly into the beam or pointing it at others.

Q: What is the maximum current consumption of this sensor?

A: The typical current consumption is around 20mA when the laser is active. Please refer to the datasheet for specific power curves.
