A Versatile Temperature Data Logger using PIC12F683 and DS1820

PIC12F683 is just a 8-pin microcontroller, but it is enough to log 254 temperature readings from DS1820 sensor in its inteernal EEPROM. Here's a tiny temperature data logger built with a PIC12F683 and DS1820. It has Start, Stop, and Send switch buttons for controlling various operations. The sampling interval is selectable to 1 sec, 1 min, or 10 min. The logged values can be sent to a PC through serial port.

It runs on 3 AAA size batteries.
