This project uses ESP8266 and ESP32 to read values from two LDR sensors and upload them to Firebase. The values are also displayed on the Serial Monitor. Additionally, an Android app is provided to ...

This project uses an LDR sensor to control a servo motor and a button in the Blynk app to control an LED connected to an ESP8266 board. The LDR sensor value is also logged to the Blynk Timeline. - ...

Monitoring Electrical Energy Consumption Through Impulse Detection Using LDR Sensors and Relay With NodeMCU ESP8266 Abstract: Activities that are very dense in humans today, often ignore their concern ...

Introduced back in June, the IKEA VINDRIKTNING is a $12 USD sensor that uses colored LEDs to indicate the relative air quality in your home depending on how many particles it sucks up. Looking to i… ...

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, ...

An LDR can typically gauge the light or dark because of its specially tuned spectral response. A light or dark sensor can be designed by using an LDR that’s connected to a voltage-divider circuit.
