This DS18B20 digital temperature sensor module is a convenient solution designed for Arduino and various microcontroller (MCU) developers. Unlike the standalone DS18B20 chip, this module integrates the required pull-up resistor and a power indicator LED directly on the PCB. No more searching for resistors or dealing with complex breadboard wiring — simply connect three wires (Power, Ground, Data) to start reading accurate temperature values, greatly simplifying your development workflow.

Key Features

  • Genuine Sensor Chip
    Uses an original DS18B20 temperature sensing chip.
  • Plug-and-Play Design
    Built-in pull-up resistor allows direct connection to MCU I/O pins with no additional soldering required.
  • Status Indicator
    Equipped with an onboard power LED for easy visual confirmation of power status.
  • Flexible Expansion
    Features a 3-pin header footprint that allows users to replace or re-solder the DS18B20 chip if needed.
  • Wide Voltage Support
    Supports 3.3V to 5V input — fully compatible with Arduino, Raspberry Pi, and various 5V/3.3V microcontrollers.

Technical Specifications

  • Size: 21mm x 10mm (compact size, space-saving)
  • Communication Protocol: 1-Wire single-bus interface
  • Temperature Range: −55°C to +125°C

Wiring Guide

  • VCC: Connect to 3.3V–5V power input
  • GND: Ground
  • DQ (or OUT): Digital signal output (connect to Arduino Digital Pin)

Package Includes

  • 1 × DS18B20 Temperature Sensor Module
