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
