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.
Download the TemperatureMonitorAndDeviceControl library from the following link.TemperatureMonitorAndDeviceControl-newDownload
Unzip and copy the downloaded library to Arduino libraries folder.
