Description: Waterproof probe with DS18B20 sensor
The DS18B20 temperature sensor is enclosed in a sealed, waterproof housing, allowing it to measure the temperature of places away from the main controller or in wet conditions. The sensor has a temperature range up to 125 °C but the insulation is made of PVC so it is recommended to keep it below 100 °C. It communicates via a 1-Wire interface and operates with voltages from 3 V to 5.5 V. The sensor is compatible with Arduino.
The sensor is hidden in a waterproof stainless steel housing.
Waterproof probe with DS18B20 sensor
The sensor communicates via a 1-Wire interface and operates with voltages from 3 V to 5.5 V. Each sensor has its own unique serial number so that multiple sensors of this type can be connected to one bus. The module allows you to select the resolution of temperature readings from 9 to 12 bits.
KEY FEATURES OF DS18B20 WATERPROOF DIGITAL TEMPERATURE SENSOR:
- 1-Wire interface only requires one MCU pin
- Multiple devices can be connected to the same 1-Wire bus
- Digital readout is less sensitive to electrical noise than analog sensors
- -10 to 85°C measurement range with 0.5°C accuracy°
- 3.3 and 5V compatible

Sensor Connections
This sensor is built into a 36″ long cable assembly. The sensor is mounted in a stainless steel can to make it waterproof, or at least water resistant. The other end of the cable is unterminated.
The corresponding wire colors are as follows:
- Red = Vdd (3.0 to 5.5V). Typically 3.3 or 5V to match the MCU it is being used with
- Black = Ground. Must be common with the MCU
- Yellow = DQ (1-Wire Data Bus) Connect to a digital I/O pin on MCU.
