Getting temperatures and acting on them

The scope of the application is a car, a greenhouse, a house, hung with thermometers (ds18b20, ds1820), some research related to measuring temperatures in the range from -55C ° to + 125C °. Controlling the temperature of batteries, expensive transistors, overheating of which can damage them, and this is a new expense of money that could be spent on more important decisions and tasks.

The application receives the measured temperature via WiFi, in the range from -55C ° to + 125C ° with a ds18b20 or ds1820 digital thermometer and displays it in the application, and according to the user configured data in the application, turns on or off the TTL signal on the Atmega16 microcontroller outputs, set by the rules for the value received temperature. It is also possible to manually turn on and off the necessary TTL signals at the outputs of the Atmega16 microcontroller.

The measurement is controlled by Atmega16 and sent to this application via WiFi module ESP8266. This is an integral part of the application, only the application works with it.

This solution can be used wherever you need a convenient measurement of temperatures, with their display on the screen of a tablet, phone, and similar devices running Androd 4.2 and higher that support WiFi, have a touch screen and have a place to save the settings files of this application, with the ability saving temperature data, as well as protocols of exchange with thermometers and the control module, in the form of files, for each thermometer separately.

The number of thermometers can be more than two; their installation in the system is done one at a time, using a special request that the application executes.
