## Description

The Adafruit Chainable DS18B20 Extender Breakout makes it easy to connect multiple DS18B20 temperature sensors in a daisy chain using standard STEMMA JST PH 2mm cables. Each breakout includes screw terminal blocks for direct connection of DS18B20 sensors in TO-92 or waterproof cable form — no soldering required. Chain multiple extenders together using 3-pin JST PH cables to build a multi-point temperature monitoring network. Each board includes a 4.7K pull-up resistor (with a cuttable trace to disable) and a buffered signal LED that blinks red during 1-Wire data transmission. Key Features Chainable Design – Daisy-chain multiple extenders with STEMMA JST PH 2mm cables Screw Terminal Blocks – Connect DS18B20 sensors (TO-92 or cable style) with just a screwdriver 4.7K Pull-Up Resistor – On-board pull-up with cuttable trace to disable when not needed Signal LED – Buffered red LED blinks during 1-Wire data transmission for easy debugging STEMMA JST PH 2mm Connectors – Standard 3-pin connectors for easy, solderless chaining Compatible Sensors Gravity DS18B20 Temperature Sensor Octopus Waterproof DS18B20 Temperature Sensor Ideal For Multi-point temperature monitoring systems Environmental and IoT sensor networks Quick prototyping with DS18B20 sensors Note: This board is an adapter/extender only — DS18B20 sensors and JST PH cables are sold separately.
