This a remote thermometer MCU: AT89S52 Temperature sensor: DS18B20 crystal: 12MHz to use serial port connection, in the PC client to use super terminal Open settings are as follows: baud rate: 4800 data bits: 8 Parity: None Stop bits: 1 Data Flow Control: No schematics see Thermometer-SCH.jpg the program prepared by the light of the Keil UV2 own son will see the use of terminal interactively EXAMPLESMEASURE In fact, this is not only a measured man, and it is also very accurate clock.
