About this document

ESP8266 LM35 Temperature Monitoring by raj is a document available to read on EtoBox.

This document summarizes how to build a temperature detection system using an ESP8266 microcontroller, LM35 temperature sensor, 2-channel relay, and Blynk app. An LM35 temperature sensor measures ambient temperature through an analog pin on the ESP8266. The voltage is converted to temperature using a formula. The temperature reading is sent over WiFi to the Blynk app using the ESP8266. A 2-channel relay is also connected and controlled to turn an LED on if the temperature exceeds 30 degrees Celsius.
