//**********************************************************
// DS18S20 example, reading
// You can connect multiple sensors to a single port
// (At the moment 4 pcs - it depends on the definition in the library)
// Measuring time: 1.2 seconds * number of sensors
// The main difference with the previous version of the demo:
// - Do not use the Delay function () which discourages by manufacturer of ESP8266
// - We can read several sensors
// Usage:
// Call Init to setup pin eg. ReadTemp.Init(2); //pin 2 selected
// Call ReadTemp.StartMeasure();
// if ReadTemp.MeasureStatus() false read sensors
// You can recognize sensors by the ID or index.
