RT18B20
The RT18B20 is a digital temperature sensor provides 9-bit to 12-bit Celsius temperature measurements。
Each RT18B20 has a unique 64 bit code and a 3 Byte Non-volatile random-access memory, and a 64 bit unique ID makes it easy for RT18B20 to network.
The Non-volatile random-access memory can be configured with temperature alarm upper and lower limits and resolution of the programming information. The chip requires almost no peripherals and has a simple circuit。
Features and Benefits
1-wire without more interface
Hight integration more simple
It is simple to use one microprocessor to control many RT18B20s distributed over a large area
can derive power directly from the data line
Has an alarm function with nonvolatile user-programmable upper and lower trigger points
Application
◆ Temperature monitor system
◆ A distributed temperature measurement
