1-Wire Temperature Sensor DS18B20+

This sensor also fits Fibaro's Smart Implant.

The DS18B20+ digital thermometer provides temperature measurements in Celsius with a resolution ranging from 9 to 12 bits. It also includes an alarm function with user-programmable upper and lower trigger points that can be stored even when power is off. The DS18B20 communicates over a 1-Wire® bus, which means it only requires one data line (and ground) to communicate with a central microprocessor. It has a wide operating temperature range from -55°C to +125°C and offers an accuracy of ±0.5°C within the range of -10°C to +85°C. Additionally, the DS18B20 can obtain power directly from the data line through "parasite power," eliminating the need for an external power supply.
