Overview

Product Overview

The DS18B20 Waterproof Digital Temperature Sensor Probe (1 meter) is a rugged, sealed temperature probe that gives accurate digital temperature readings using the 1-Wire interface. It is perfect for Arduino and Raspberry Pi projects because you can run multiple DS18B20 sensors on a single data pin and read stable temperatures without analog noise issues. The waterproof metal probe format makes it ideal for water tanks, aquariums, outdoor experiments, fermentation setups, HVAC monitoring, and any project where a normal bare sensor would not survive.

Questions & answers

Frequently asked questions

Yes. It uses the standard DS18B20 digital 1-Wire interface, so it works with Arduino and Raspberry Pi projects that support 1-Wire temperature sensors. Raspberry Pi setups typically require enabling the 1-Wire interface in software.
The sensor element is sealed inside a waterproof metal probe with a 1 meter cable, so it is ready for wet or outdoor placement. You still need to wire it to your controller and use suitable DS18B20/1-Wire software.
It communicates digitally over 1-Wire, allowing multiple DS18B20 sensors to share a single data pin. Typical wiring uses power, ground, and data, with a pull-up resistor on the data line for reliable communication.
Yes. The sealed waterproof probe format is intended for water tanks, aquariums, fermentation setups, outdoor experiments, and HVAC monitoring. It provides digital temperature readings, which helps avoid analog noise issues common with long sensor leads.
Common causes are reversed wiring, missing data-line pull-up resistor, no common ground, or the 1-Wire interface not enabled on a Raspberry Pi. Also verify the wire color mapping, because waterproof probe cable colors can vary by supplier.
