IoT Temperature Data Logger Using ESP8266 and LM35

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.

Temperature and Humidity Data Logger using Arduino

In this project, we are going to make a temperature and relative humidity data logger. Arduino is the brain of this project. DHT22 sensor is used for sensing temperature and relative humidity. Arduino Uno is programmed to read temperature, humidity values from DHT22 sensor and save it to a file in an SD Card. So whenever required we can take the SD Card for viewing data. Here we will take data from SD card and import it to excel to...
