Home Security System: Camera + App Alerts on Intrusion Detection
An ESP32-CAM paired with a PIR sensor: it only takes a photo and fires a webhook/Telegram-style alert when it genuinely detects motion, with debounce logic to prevent false alarms.
Smart RFID Door Lock + App Control
An ESP32 with an RC522 RFID reader unlocks the door with a valid card, while also hosting a local HTTP API for remote unlocking from an app — both paths share the same lock logic and auto-relock after a few seconds.
Smart Farm

Smart Energy
Smart energy monitoring/control projects.
Solar Energy Monitoring and Control System with ESP32
Build a low-voltage DC model using an ESP32 to measure solar voltage, current, and power, monitor a battery, and control a DC load over MQTT.
Automatic Smart Lighting Based on Ambient Light and Schedule
ESP32 automatically turns an LED/relay light on or off based on an LDR light sensor and an NTP-synced schedule — it only turns on when it's dark out and within the configured time window.
Solar Panel Performance Dashboard
An ESP32 measures a solar panel's output voltage and current with an INA219 sensor, displaying the readings in real time on a local OLED screen and a simple web dashboard hosted right on the ESP32.
Environment
Environmental monitoring and protection projects.
Water Quality Monitoring System
Build a water quality monitoring system that measures temperature, TDS, pH, and turbidity, shows an alert status, and can be extended to send real-time data over MQTT. Suited for monitoring fish tank, hydroponic, or water tank quality, or as a reference monitoring model. Note: readings from consumer-grade sensors do not replace certified testing equipment or lab analysis.
Smoke & Gas Leak Alarm Over 4G SIM — Automatic SMS + Phone Call Alerts
ESP32 reads an MQ-2 sensor to detect smoke and gas leaks, and when the level crosses the threshold it automatically sends an SMS and then calls twice, two minutes apart, over a SIM A7680C 4G module.
Pond Water Level Monitor for Aquaculture
Uses an HC-SR04 ultrasonic sensor on an ESP32 to measure aquaculture pond water level in real time, with a local buzzer alert when the level is too low or too high.
