Adafruit DS18B20 Chainable Temperature Sensor Breakout with STEMMA JST PH Connector

Description

The Adafruit Chainable DS18B20 Extender Breakout is designed to make chaining DS18B20 temperature sensors easier, especially when testing with adafruit.io’s WipperSnapper service. This adapter allows you to connect DS18B20 sensors using JST 3-pin cables without complex wiring, featuring screw terminal blocks for easy sensor connection.

Each extender includes a 4.7K pullup resistor on the data line that can be disabled by cutting a trace, and a red LED indicator that blinks to confirm data transmission on the 1-Wire bus.

Note: The board does not include the DS18B20 sensor itself; sensors and JST PH-compatible 3-pin cables must be supplied separately.

• Easy chaining and connection of DS18B20 temperature sensors
• Screw terminal blocks for TO-92 or cable-style DS18B20 sensors
• 4.7K pullup resistor on board (can be disabled)
