Temperature Sensor DS18B20 for Arduino and Raspberry

The DS18B20 is a digital temperature sensor with 1-Wire communication in a TO-92 package, factory calibrated. One digital input is enough to read it, and several sensors can share the same input. A 4.7 kΩ resistor between VCC and Data is required for operation, and only one even with several sensors on the same input.

Recommended waterproof alternative: Waterproof Temperature Sensor (DS18B20) 1m

Recommended Accessories:

• Resistance Set 600 pcs. Assorted 1/4W 1% Accuracy

Features:

• Each sensor has its own serial number, so several can share one input
• 4.7 kΩ pull-up required, the internal pull-ups of the Arduino are not sufficient
• Arduino libraries «DallasTemperature» and «OneWire» in the Library Manager

Application Examples:

• Temperature measurement on a breadboard or perfboard
• Several measuring points on one input
