DS18B20 TO-92 Digital Thermometer Temperature IC Sensor

DS18B20 TO-92 Digital Thermometer Temperature IC Sensor Overview:

The DS18B20 digital thermometer is a high-resolution (9-bit to 12-bit) Celsius temperature sensor with a built-in alarm and user-programmable alarm level. The sensor uses a 1-Wire bus that requires data, power and ground. Each sensor has a unique ID, allowing them to be configured and identified on the same bus. Distributed machines, buildings, and process control are common applications.

This sensor was brought into Parallax inventory for use in the P2 Quick Byte series as a demonstration device for the 1-Wire Object. This part is easily wired into a breadboard, too.

DS18B20 TO-92 Digital Thermometer Temperature IC Sensor Features:

• Temperature sensing in the -55 °C to + 125 °C range
