Object Counter System — ESP32 + IR Sensor + LCD
Overview
A practical and easy-to-build ESP32-based project that accurately counts objects passing in front of an IR sensor and displays the real-time tally on an I2C LCD screen. It includes debouncing for reliability, plus serial commands for testing and resetting.
Key Features
- Accurate Object Detection: The IR sensor detects when objects pass by (active-LOW output), and the ESP32 increments a counter accordingly.
- Visual Feedback: A 16×2 I2C LCD shows live count updates.
-
Control & Debug: Serial commands like
reset,test, andscanallow easy testing, resetting counts, and checking I2C connectivity.
