Digital thermometer based on DS18B20. Converts the 9-bit code representing the digitally converted temperature data to 12-bit. It has an alarm function with non-volatile, user programmable higher and lower starting points. The information is sent / received via a single bus (the second conductor is a ground, a chassis). The busbar must be connected between the central microprocessor and the thermometer. The power supply can be taken from the data line and no external power supply is needed.
