Reliable industrial sensing

Using this for a conveyor belt counter. The fast response time ensures no items are missed. The build quality feels robust enough for light industrial applications.

Great range, needs careful mounting

The 40m range is impressive for the price. It works well for perimeter monitoring. Just ensure it is mounted securely as the small angle means precise alignment is key.

Best value laser module

We bought ten of these for our student robots. They are consistent, durable, and the horizontal ranging is very reliable. Highly recommend for educational kits.

Solid performance, good documentation

Integration into my Python script was easy thanks to the clear pinout diagram. The human body induction feature works well for security alerts. Slightly warm after continuous use but within specs.

Waterproofing holds up

Used this on an outdoor rover that occasionally gets splashed. The IP65 rating is legitimate; no issues after several weeks of damp conditions. Data output is stable.

Perfect for my robotics project

This sensor is incredibly accurate for obstacle avoidance. The small beam angle helps distinguish between close objects better than ultrasonic sensors. Setup with Arduino was straightforward.

5 FAQ

Q: Does this module work directly with Raspberry Pi GPIO?

A: Yes, it operates at 3.3V-5V and uses UART/TTL, making it fully compatible with Raspberry Pi GPIO pins without needing extra level shifters.

Q: What is the maximum update rate for the distance data?

A: The sensor can provide up to 20 measurements per second (20Hz), which is sufficient for most robot navigation and obstacle avoidance tasks.

Q: Does the waterproof rating allow submersion?

A: No, the IP65 rating protects against water jets and rain but does not support submersion in water. Please keep it above water levels.

Q: Can it measure distance through glass?

A: Laser sensors generally reflect off glass surfaces, which may cause inaccurate readings or measure the distance to the glass itself rather than objects behind it.

Q: Is the laser visible to the naked eye?

A: Yes, it emits a faint red dot similar to a standard laser pointer, which helps in aligning the sensor during installation.
