IoT projects for electronics hobbyists, beginners, college students and for educational purposes. Circuit diagram, working explanation and program code.
In this project, we are going to log and monitor temperature data over internet using ThingSpeak IoT server. And we can view the logged data and graph over time in their website. It is made using ESP8266 WiFi module and LM35 temperature sensor. ESP8266 WiFi chip reads the current temperature from LM35 using ADC and sends it to ThingSpeak server for live monitoring from anywhere in the world.
