Temperature Sensor - Waterproof (DS18B20)

Product Overview

This sealed digital temperature probe lets you precisely measure temperatures in wet environments with a simple 1-Wire interface. The DS18B20 provides 9 to 12-bit (configurable) temperature readings over a 1-Wire interface, so that only one wire (and ground) needs to be connected from a central microprocessor.

Note: The pinout for this sensor is as follows: RED=Vcc BLACK=GND WHITE=SIG

Dimensions: Probe is 7mm in diameter and roughly 26mm long. Overall length (including wire) is 6 feet.

Features:

• 3.0-5.5V input voltage
• Waterproof
• -55°C to+125°C temperature range
• ±0.5°C accuracy from -10°C to +85°C
• 1 Wire interface
