Description
This product is shipped from Sydney, Australia. Worldwide shipping available- we ship to USA, Canada, New Zealand, UK, EU and Non-EU countries.
We are now selling a both fully assembled version of this module with 3D printed enclosure. It comes with a laser module. All included in one package.
You can use this 3 digits digital object counter for counting objects or people entering into a room. It can be used by engineers for learning about digital counters.
This DIY digital object counter works with a photoresistor and there are three seven segment displays displaying numbers from 000 to 999.
Works with a laser module
Turn on the laser module and direct it towards the photoresistor and hit the photoresistor with the laser beam so that whenever the laser is blocked, the counter would count.
The counter module works with 5V. You just need to power up the kit using a 5V mobile charger or any other power adapter.
Dimension of the PCB: 43 mm* 58 mm
Features:
- The distance between the transmitter and receiver modules can be around 10 meters.
- The counter module can be reset to 0 at any time and restart the counting.
What’s NEW ?
- The output of the kit is highly stable, there is no false count at all.
- The kit has photoresistor only. We have removed infrared feature.
Package Includes:
- 1 x 3 digits counter module – Fully assembled- with 3D printed enclosure
- 1 x laser module with 3D printed enclosure.

About 3D printed enclosure:
Small layer lines, marks and glue marks are normal characteristics of a 3D printed enclosure. It is not intended to compete with an injection-moulded enclosure in cosmetic perfection; instead, it is designed to work well, hold your electronics securely and give your project a professional finished appearance.
