![]() ![]() The various modes and functionality associated with the operation of several devices on a single line, with an alarm signal, and others in this article, I do not consider. Multiple sensors can be connected to the same communication line.In this mode, to connect the device to the microcontroller, two wire lines are enough. Supports “parasitic power” mode in which the sensor receives power from the communication line.Information is transmitted via a 1-Wire serial protocol only three wires are required to connect the temperature sensor to the microcontroller.The sensor converts the temperature into a digital code, i.e.Wide range of temperature measurement -55.Resolution is set by software and reaches 0.0625 ° C for a maximum resolution of 12 bits.The sensor is calibrated during manufacture, does not require additional calibration. High accuracy of measurement, the error does not exceed 0.5 ° C. ![]() Now I will emphasize the features of this device, thanks to which it became so widespread. The sensor has unique parameters and functionality. The DS18B20 is an integral temperature sensor with a 1-Wire digital serial interface. ![]() Previous lesson List of lessons Next lesson In the lesson we will learn how to connect a DS18B20 temperature sensor to the Arduino board, how to control it using the OneWire library. ![]()
