Description DS18B20 Module Single Bus Digital 18B20 Temperature Sensor Electronic Building Blocks The DS18B20 digital thermometer provides 9-bit to 12-bit Celsius temperature measurements and has an alarm function with nonvolatile user-programmable upper and lower trigger points. The DS18B20 communicates over a 1-Wire bus that by definition requires only one data line (and ground) for communication with a central microprocessor. In addition, the DS18B20 can derive power directly from the data line (parasite power), eliminating the need for an external power supply. Details: DS18B20 Temperature Sensor Single Bus Digital Temperature Sensor Module For Arduino Diy KitFeatures:Made of Environmentally friendly materials material, durable Exquisite workmanship. Mini size, easy to carry. Precision continuous self-calibrating analog/digital. Greatly reduces current consumption during idle periods. Typical applications include portable instrumentation industrial process control and small transmitters.
