Everything included in the box:

• 🔩 Build your own DIY Smart Classroom Assistant using ESP32, ESP32-CAM, ultrasonic sensing, OLED display, and a 4-channel relay module. This hands-on educational kit demonstrates how modern classrooms can use sensors, IoT communication, camera-based monitoring, and automation to manage classroom appliances.
• 🔩 Students will assemble the circuit, connect the sensors and modules, program the ESP32, and test the complete system. The project demonstrates student presence/counting concepts, automatic light and fan control, classroom status monitoring, and relay-based appliance automation.
• 🔩 The ESP32 acts as the main controller, while the ESP32-CAM provides camera-based monitoring. The ultrasonic sensor detects movement or entry events, the OLED displays classroom information, and the 4-channel relay controls connected lights and fans.
• 🔩 This kit is ideal for school STEM projects, diploma projects, engineering students, college exhibitions, IoT learning, and DIY electronics education.
