Schematics Serial Temperature Sensor Data Logger

Posted on Feb 5, 2014

The program in the microcontroller knows two protocols; the one wire bus used by the DS1820 temperature sensor, and the serial protocol expected by your computer. Once power is applied, the program fetches data from the sensors and sends it to the serial port, repeatedly. The data from the DS1820 arrives in a format peculiar to the sensor. The pro
