RT18H20

The RT18H20 is a digital temperature sensor provides 9-bit to 12-bit Celsius temperature measurements。
Each RT18H20 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 RT18H20 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。
