ALLNET 4duino Temperature 1-Wire (DS18B20) Sensor Module

The ALLNET 4duino Temperature 1-Wire (4duino_B20) is a digital temperature sensor module based on the DS18B20 sensor, designed for the ALLNET 4duino platform and compatible Arduino microcontrollers. It communicates via the 1-Wire bus and provides accurate temperature readings from -55°C to +125°C with a configurable resolution of 9 to 12 bits. Each sensor has a unique 64-bit serial code, enabling multiple sensors on a single bus.

Advantages

High accuracy of ±0.5°C in the -10°C to +85°C range, low operating voltage (3.0V to 5.5V DC), and support for both standard and parasitic power modes. The digital output eliminates noise issues common with analog sensors.

Suitable for

• Environmental monitoring
• Industrial control systems
• Home automation
• IoT projects
• Temperature logging
