Description
This is an upgraded version of the previous digital objects counter kit. The device has 2.3" common cathode seven segment displays. The kit is based on the CD4026 decade counter.
How does it work?
A laser light module illuminates the photoresistor continuously and whenever any object obstructs the laser light falling on the photoresistor, the counter increases the count. You can use this 3 digit digital objects counter for counting objects or people entering a room. It can be used by engineers for learning about digital counters.
NOTE: It does not have a microcontroller, so, it does not store the count. Once the device is turned off, the count resets to 000.
The device comes with a large photoresistor (12mm) so that the laser can easily illuminate the sensitive area of the photoresistor.
Features:
- It counts from 001 to 999.
- It is an up counter. It does not count down.
- Each seven segment display is 2.3" big.
- The distance between the counter module and the laser can be up to 100 meters. It works as long as you can illuminate the photoresistor with the laser.
- It works with a 9V power supply. Please note that the power supply should be strictly 9V.
- Dimension:165mm*91mm
Package includes:
- 1 x 2.3" digital objects counter- Comes assembled
- 1 x laser light module
NOTE: You need to purchase a 9V power supply for this device.
