DS18B20 Digital Temperature Sensor Module (3-Pin)

Description

About this item:

The DS18B20 Digital Temperature Sensor Module is based on the DS18B20 IC and communicates via the 1-Wire protocol. It comes with a built-in pull-up resistor and a compact PCB, making it easy to interface with microcontrollers like Arduino, ESP8266, ESP32, and Raspberry Pi for accurate temperature measurement.

Pin Configuration:

• S (Signal): Data line (1-Wire interface)

• + (VCC): Power supply (3.3V / 5V)

• – (GND): Ground

Key Features:

• Temperature Range: -55°C to +125°C

• Accuracy: ±0.5°C (–10°C to +85°C)

• Resolution: Programmable (9 to 12 bits)

• Interface: 1-Wire digital communication (single data line)

• Form Factor: Small, breadboard-friendly design

• Extras: Pre-mounted pull-up resistor on board

Applications:

• Environmental monitoring

• HVAC systems

• Industrial automation

• IoT and smart home devices

• Food and cold chain monitoring
