Maxim’s 1-Wire digital temperature sensor.  It measures temperatures between -55 ° C and + 125 °C with an accuracy of 0.5 °C. Each sensor is equipped with a 64-bit serial code stored inside, this allows you to use a huge number of sensors on a data bus. Applications include thermostatic controls, industrial systems, consumer products, thermometers, etc.
