TYPE 1- 4 Digits Digital Objects Counter with WiFi Support

TYPE 1- ESP32-Based 4-Digit Digital Object Counter (0–9999) Overview This ESP32-powered 4-digit digital counter is a smart and versatile device designed to count objects automatically or manually. It can display values from 0 to 9999 using a bright, colorful LED matrix display. The system uses a photoresistor–laser beam mechanism to detect passing objects and increment the count with precision. How does it work ? With built-in WiFi, you can access a browser-based control panel directly from your phone or computer—no app installation required. Simply connect to the ESP32’s WiFi access point and manage the counter wirelessly. Demo Video: Check out all the images at https://photos.app.goo.gl/EUANG7gzdtjcTesr9 Common Features: Automatic Object Counting: A laser beam constantly shines on the photoresistor. When the beam is interrupted (object passes through), the counter increases/decreases by one. Users can restrict photoresistor from counting via web interface. Manual Controls Three onboard buttons let you control the counter easily: UP: Increase count manually DOWN: Decrease count manually RESET: Reset the counter to zero WiFi Access & Web Control: Connect to WiFi network: SSID and password will be given to customers. Open browser and visit http://192.168.4.1 Access an intuitive web interface to: Increment or decrement the count remotely Set a specific count value, for example, 453 Stop further counting after reaching the target value Enable or restrict photoresistor-based counting when required Change display color. Options are: RED, GREEN, BLUE, WHITE and YELLOW. Customizable Display Colors: Choose from five vivid colors — Yellow, Red, White, Green, and Blue — for the 4-digit display. Use web interface for changing colors. Colors are saved even power is turned off. Data Memory (Power Loss Protection): The ESP32 automatically remembers the last count and color settings, even after power disconnection. Display Options: Can be used with two display sizes, P3 INDOOR Display (3-inch digits)-192mm x 96mm Included P5 INDOOR Display (5-inch digits)- 320mmx160mm- you can choose to purchase separately Both use 64×32 LED matrix panels for clear, high-contrast numbers. Power Supply: Works with 5V 4A power adapter. Plug-and-Play Design: No assembly required. Comes fully pre-wired and tested. Enclosure is included. Includes Laser Module: High-quality laser emitter included for reliable photoresistor detection. Applications & Uses This counter is suitable for a wide range of industrial, commercial, and hobby projects, including: Factory or workshop production lines – count items as they pass on a conveyor. People counters – monitor entries or exits through a doorway. Event or game scoring systems – track scores or hits. DIY electronics projects – educational or experimental use. Inventory or packaging lines – automatic quantity tracking. Exhibition and display counters – show live object or visitor counts.
