ESP32 Email Alert Based on Temperature Threshold (change values on web server) 

For complete project details (schematics + source code), visit ► RandomNerdTutorials.com/esp32...
Learn how to send an email alert with the ESP32 based on a temperature threshold. The ESP32 also hosts a Web Server that shows the latest sensor readings and input fields to change the threshold value, email's recipient, and the option to arm or disarm the system.
We'll read the temperature using a DS18B20 sensor and send emails using an SMTP Server. The ESP32 will be programmed using Arduino IDE.
