DS18B20 Temperature Sensor Module
Description:
DS18B20 Temperature Sensor Module is a digital temperature sensor designed for precision temperature monitoring in a wide variety of applications. Unlike traditional analog temperature sensors, the DS18B20 provides accurate temperature readings in a digital format over a single-wire (1-Wire) communication interface, making it ideal for microcontroller-based projects like Arduino, ESP32, Raspberry Pi, and other embedded systems. Module integrates the popular DS18B20 sensor chip along with supporting components mounted on a small PCB for easy connection and reliable performance.
Features:
1. Digital Temperature Sensor (No need for ADC conversion)
2. 1-Wire Interface (Only one data pin needed for communication)
3. Measures temperatures from -55°C to +125°C
4. Accuracy of ±0.5°C in the range of -10°C to +85°C
5. Unique 64-bit Serial Code (Each sensor has a unique address)
6. Waterproof versions available (for harsh environments)
7. Multiple sensors can be connected on a single data line (ideal for networking sensors)
8. Small, durable, and low-cost
