Fibaro Temperature Sensor The sensor DS-001 is a digital thermometer with programmable resolution of 9 to 12 bits. It is suitable for measurement of the temperature in homes or offices. The accuracy is 0.5 C over a range of -10 C to 85 C. The sensor is very small and can therefore be placed anywhere. In addition, each sensor is addressed with a 64-bit code. For this reason several sensors can be connected to a single 1-Wire line. The power supply of 3 V to 5.5 V is directly powered via the data line.
