Elsys Temperature Sensor - Wired - 1-Wire (DS18B20, 1m Cable)

The Elsys Temperature Sensor is a high-precision, wired digital temperature sensor designed for reliable temperature monitoring in a wide range of applications. Featuring the Maxim DS18B20 sensor chip, it communicates via the 1-Wire bus, making it easy to integrate with microcontrollers like Arduino and Raspberry Pi, as well as dedicated 1-Wire controllers. The sensor comes with a 1-meter PVC cable and a stainless steel probe with IP67 protection, suitable for both indoor and outdoor use.

Advantages

High accuracy of ±0.5°C in the -10°C to +85°C range, configurable resolution from 9 to 12 bits, and a wide measurement range from -55°C to +125°C. The robust stainless steel probe ensures durability, while the 1-Wire interface allows multiple sensors to be connected on a single bus.

Suitable for

• Indoor and outdoor temperature monitoring
• HVAC systems
• Industrial control
• Home automation
• Weather stations
• Data logging projects
