Waterproof Temperature Sensor (DS18B20) 3m

This waterproof temperature sensor contains a digital DS18B20 with 1-Wire communication in a metal probe. The chip is 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 alternative with shielded cable: 3m Waterproof DS18B20 Shielded Temperature Sensor

Recommended Accessories:

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

Features:

• Digital temperature sensor DS18B20 with 1-Wire interface
• 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 in liquids and outdoors
• Several measuring points on one input
• Connection to a Shelly Plus AddOn
