Description: Single bus interface means connected with the microprocessor requires only one port line can DS18B20 microprocessor with two-way communication. Single bus with the economy is good, anti-interference ability, in the harsh environment of the site for temperature measurement, ease of use, enabling users to easily set up the sensor network, the construction of measurement system introduces a new concept.
(2) Measuring temperature range, high accuracy measurement DS18B20 range of-55 ℃ ~+ 125 ℃ in the-10 ~+ 85 ° C within an accuracy of ± 0.5 ° C.
(3) in use does not require any external components.
(4) holding more than DS18B20 network function can be connected in parallel only a single line, multi-point temperature.
(5) power supply through the internal parasitic DS18B20 flexible circuit from the data line to get power. Therefore, the timing of when the data line to meet certain requirements, you can not receive external power, so that the system structure more
