ESP32-Freezer-Alarm

ESP32 Temp Alarm using DS18B20, wifi manager, Email alert Threshold. I made this alarm using several tutorials from https://randomnerdtutorials.com/. It has a Wifi Manager, so you dont have to hard code the wifi data into it. Uses a DS18B20 waterproof sensor. Has a Wifi Reconnect function. Has an email alert if Sensortemp reading goes over setpoint, and alerts when it goes back down.

To use, make sure all the libraries labeled below are installed in your Arduino IDE. Put the wifimanagefreezer folder into your Arduino home folder. Wifimanagefreezer should have the wifimanagefreezer.ino file in it and the data folder. The data folder should have the nine .txt files, two html files and one css file.

Need to add .txt files to the Data Folder as below check.txt, email.txt, epass.txt, input.txt, inputcc.txt, input3.txt, ip.txt, pass.txt and ssid.txt

Libraries Used: ESPAsyncWebServer--This and AsyncTCP installed using DS18B20 tutorial AsyncTCP @ https://randomnerdtutorials.com/esp32-ds18b20-temperature-arduino-ide/

OneWire 2.3.6

DallasTemperature 3.9.0

ESP32 Mail Client 2.1.6

After first power-up, Connect to the ESP32 wifi

Then go to IP address 192.168.4.1 to setup your wifi credentials and the Email account that will send the alerts

Then the System will Reboot and go to the ip address that you set or defaulted 192.168.1.200

***!!Make sure to reconnect to your WiFi!! Type in the IP address in your browser
