My attempt is to create a prototype version of Smart Curtains using ESP32 ... circuit is very simple. Any kid will also be able to make it. You just need basic breadboard skills. Connect wires as per ...

For this, we need a light sensor ... LDR is achieved because it is a property of semiconductor material used on the surface. We previously made many Circuits using LDR, which use LDR to automate the ...

I have used the INPUT_PULLUP function in Arduino IDE instead of using the pull-up resistors ... I have soldered all the components as per the circuit diagram. Then connect the ESP32 board, DHT11 ...

Uses a Kalman filter to smooth and correct sensor readings. - Reads ambient light levels using an LDR sensor. - Communicates sensor data wirelessly via Bluetooth. - Sends processed values over serial ...

Abstract: This paper presents a Smart Street Lighting System using IoT technology ... The system comprised an STM32 microcontroller, an ESP32 Wi-Fi module, LED lights, an IR sensor, an LDR sensor, ...
