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. Components Required ESP8266 LM35 Breadboard Connecting Wires Hardware Circuit Diagram LM 35 with ESP8266 - Circuit Diagram Connections ...

Digital Thermometer using LM35 Sensor and ESP8266

In this project, we are going to monitor the current room temperature over internet using ESP8266 programmed as a web server. It is accomplished by establishing data communication between ESP8266 WiFi module and LM35 temperature sensor using ADC. Components Required ESP8266 LM35 Breadboard Connecting Wires Hardware Circuit Diagram LM 35 with ESP8266 - Circuit Diagram Circuit Connection Connect 3.3V pin of ESP8266 to first pin of LM35 Connect A0 pin of ESP8266 to second pin of LM35 Connect GND pin of ESP8266 to third pin of...

Digital Thermometer using PIC Microcontroller and LM35 Temperature Sensor

Basics A Digital Thermometer can be easily constructed using a PIC Microcontroller and LM35 Temperature Sensor. LM35 series is a low cost and precision Integrated Circuit Temperature Sensor whose output voltage is proportional to Centigrade temperature scale. Thus LM35 has an advantage over other temperature sensors calibrated in Kelvin as the users don't require subtraction of large constant voltage to obtain the required Centigrade temperature. It doesn't requires any external calibration. It is produced by National Semiconductor and can operate over a -55 °C to 150...
