Review: Great Budget Sensor - I purchased these sensors to monitor the level in a dust collector bin. For the price, they work very well and have performed reliably so far. Just be sure to double-check the wiring: these sensors use slightly different wire colors for sensor, ground, and positive compared to other similar models, so review the included schematics or look up the correct wiring online. Great value for the money if you need a basic, budget-friendly sensor!
Review: Great for simple object detection in close proximity. - Purchased these for a fun work project where I needed to detect a cup. They are very easy to adjust and very accurate for object detection. The output pin stays high until an object is detected and goes low until it is moved out of range again. To reduce sensitivity turn the screw counter clockwise. It takes a while, don't worry. I pointed it at the floor and gradually made the necessary adjustments, you have to allow the light on the back of the unit to go off, make an adjustment, then move it towards the floor until the light goes on, rinse/repeat. If you just turn the screw it will not turn the indicator LED off. Image added for the wonky color scheme black is output, brown is 5V, and blue is ground.

## Features

- This is a collection of emission and reception in one photoelectric sensor.
- Detection distance can be adjusted according to requirements.
- The sensor has a detection range, interference by visible light small, easy to assemble, easy to use and so on.
- Can be widely used in robot obstacle avoidance, assembly line and many other automated products.
- Photoelectric sensor (photoelectric switch) NPN normally open.

### ⭐⭐⭐⭐⭐ They work great
*by M***7 on January 18, 2024*

I wish I could have bought just one but they came in a 3 pack. You need a pull up resistor on the output but no biggie. I use a 3.3K ohm but anything between 1K and 10K would work I think.
