Infrared Wireless Visitor Counter

Was skeptical at first due to the cost and where I planned on using it, but after running it for over a year in an industrial environment (steel industry) I would highly recommend it as an alternative to manual counting. I have implemented the use of this device for counting steel finished bar leaving one of our cutting machines and it has yet to fail and has been fairly accurate. This is a very simple install (you may have to create your own box depending on location) just power in and power to the sensor from the counting unit. Great value for the cost!

So my little one got a hamster for Christmas. The kids named him Chorky. Fun fact about hamsters: they are corpuscular (awake at dawn and dusk) or nocturnal. So Chorky runs on his wheel darn near all....night....long. We all wondered, "how far is this little guy actually running? For a fat little rodent, he sure runs an unbelievable amount!" So I decided to make it into a little science experiment and a teaching project. I'll have the kid log and reset the revolutions daily for a couple of weeks. The hall effect sensor is 3-wire and threaded on its main body. The kit comes with a mounting bracket for the hall effect sensor, 2 washers and 2 nuts that thread on to the sensor body. The sensor itself has an LED light that blinks when it senses the magnet. The magnet is quite small and comes in a separate little baggie. One thing I noticed about the magnet is that the sensor would only pick up one side, not the other, so I'm glad I tested it out before mounting the magnet. I marked the side that the sensor picked up with a sharpie so that when I epoxied it to the little hamster wheel, I had it in the correct orientation. The base counting unit is simple, with 6 digits of good old fashioned clear bright 7 segment LED. I'm a fan of the "just ripped it out of a piece of industrial equipment" look. The rear has 5 terminals: 3 for the sensor and 2 for the 110VAC. Make sure you receive the correct voltage model, which is indicated by a filled in square on the label on top of the unit. In addition to the one I purchased, 110-240VAC, I noticed there are 3 other models: 12-24v DC, 36v DC, and 380v AC. These units use the indicated voltage, so for the 110-240 unit the included 2 blade wall outlet plug wires right up, no transformer / wall wart needed. Setup with this counter was a breeze. The included instructions were clear on how to wire the 5 terminals, for two power wires and either the included 3 wire hall effect sensor, or for a 2 wire simple contact switch. Either will trigger this counter, so it's flexible in its usage. Finally, I'm glad to know I'm not the only lunatic out there attaching an electronic counting rig to my kid's hamster wheel. I noticed when looking at another counter setup (similar base unit but with an optical sensor), somebody asked in the questions section if that setup would work for a hamster wheel. To that other soul asking that question: this! This is the setup you want!

This product is more meant for an industrial application where the installer is certified in electrical safety and the device is protected by a properly rated enclosure. It works great and does the job, but I was surprised by the exposed 120V wires. Fortunately I know how to deal with that but if you aren't comfortable with electricity, this product is not for you.

Easy and simple to hook up. Red LED display is bright and easy to read. I’m counting Hoist Lifts so the prox sensor was much more sensitive than I needed so I connected the controller to a rotary limit switch using terminals 1&2 for the limit switch N/O and terminals 4&5 for the 120v power. Works perfectly!!

Good product

this counter works ok but it does freeze up, I would not recommend if you have high quantities to count

I bought this for my dad because he walks laps inside in the winter. Its a great little sensor. I 3d printed a case so I could mount it to the wall. It works great and have had no issues with the counter.

Sensors do not work with controllers. Changed to sensors we had in house. Those worked.

The products (counter and optical sensor) seem well made and it even includes a bracket to mount the sensor. The instruction sheet is in English and is adequate in order to wire the system correctly. The plug on the supplied mains cable did not have much retention in a socket and sometimes did not make contact, but that is a minor issue. I was trying to count the oscillations of a brass pendulum. Whenever the pendulum moved in front of the sensor, the counter increased by 4 or 5 counts or more. I ascribe the problem to the reflective surface of the pendulum, but whatever the reason, this purchase was not right for my application.

the only problem , the sensor as to be at least 12 inches away. Otherwise works well.

Did not work - counter looked used.
