Real time temperature monitoring and device control from mobile App developed on Flutter through NodeMCU

A temperature monitoring system which will turn ON a device such as cooling fan, when the temperature is increased above an upper threshold. Similarly, device will be turned OFF when the temperature is decreased below lower threshold. In between lower threshold and upper threshold, device will continue its state. Circuit is done as shown in the following diagram.
