This is a pre-wired and waterproofed version of the DS18B20 sensor.

Handy for when you need to measure something far away, or in wet conditions. While the sensor is good up to 125Ā°C the cable is jacketed in PVC so we suggest keeping it under 100Ā°C. Because they are digital, you don't get any signal degradation even over long distances!

These 1-wire digital temperature sensors are fairly precise (Ā±0.5Ā°C over much of the range) and can give up to 12 bits of precision from the onboard digital-to-analog converter. They work great with any microcontroller using a single digital pin, and you can even connect multiple ones to the same pin, each one has a unique 64-bit ID burned in at the factory to differentiate them. Usable with 3.0-5.0V systems.

We toss in a 4.7k (for long cable) & 2.2k (for short cable) resistor, which is required as a pullup from the DATA to VCC line when using the sensor.Ā

What is included with the waterproof DS18B20 sensor and how does it help in wet or long distance installations?
It is a pre wired waterproof version and includes pullup resistors for the data line, 4.7k for long cables and 2.2k for short cables.
How many sensors can be connected on a single data line?
The device supports a multidrop configuration with multiple sensors on the same 1 Wire data line; each unit has a unique 64 bit serial code to identify it.
What voltage does it operate at and can it be powered from the data line?
It is usable with 3.0 to 5.0 volt systems and the power supply range is 3.0 to 5.5 volts.
What temperature range and accuracy does the sensor provide?
It measures -55 C to +125 C and offers about plus minus 0.5 C accuracy over much of the range; resolution is selectable from 9 to 12 bits.
Why would I choose this sensor for wet or long distance sensing?
Digital 1 Wire communication provides no signal degradation over long distances and the waterproof pre wired assembly is designed for wet environments.
