Introducing the DS18B20 Digital Temperature Sensor from NXP

The DS18B20 is a versatile and reliable digital temperature sensor from NXP Semiconductors, designed for easy integration into a wide range of applications. This sensor offers high-precision temperature measurements with a digital output, making it an ideal choice for environmental monitoring, HVAC systems, and industrial control processes.

Key Features

• High Accuracy: The DS18B20 provides ±0.5°C accuracy from -10°C to +85°C, ensuring precise temperature readings for critical applications.
• Wide Temperature Range: Capable of measuring temperatures from -55°C to +125°C, this sensor is suitable for extreme environmental conditions.
• Programmable Resolution: Users can configure the resolution of the DS18B20 from 9 to 12 bits, allowing flexibility between resolution and conversion time.
• One-Wire Interface: The sensor uses NXP's proprietary one-wire bus, which simplifies system design by requiring only one data line (and ground) for communication with a central microprocessor.
• Multiple Sensors on One Bus: It is possible to operate several DS18B20 sensors on the same one-wire bus, making it easy to implement multi-point temperature sensing networks.
• Power Supply Range: The sensor can be powered from a 3.0V to 5.5V supply, or it can derive power directly from the data line ("parasite power"), minimizing the need for an external power supply.
