The LDR sensor is used to detect the ambient light level and open or close the servo motor based on the sensor's reading. The button in the Blynk app is used to turn an LED on or off. This project ...

Este repositório contém o código para um projeto IoT usando um ESP8266 para ler dados de um sensor LDR (Light Dependent Resistor) e enviá-los para a plataforma ThingSpeak. O projeto conecta o ESP8266 ...

Say, you’re starting your electronics journey with a few projects in mind. You have an ESP8266 board like the Wemos D1, a Li-Ion battery, you want to build a small battery-powered sensor that… ...

NodeMCU ESP8266 as a micro controller will process data from the thermal camera and LDR sensor to be sent to the relay actuator as output. From the designs and experiments that have been carried out, ...

The devices used are impulse indicator LED on kWh Meter which can be censored by LDR every time the LED blinks, relay as remote control switch via the internet, NodeMCU ESP8266 as processor and sender ...
