This device, based on an Atmel ATMega168 microcontroller can monitor up to 16 DS18x20 thermometers, with a variable logging rate of 5 to 9999 seconds. The data is displayed on a multi-page LCD display for immediate viewing as well as being sent via RS232 at 19200 baud for recording. Data is time-stamped with an optional on-board 1-Wire real time clock.
Author says: This began as a simple monitor for a friend to keep track of the temperature of his bicycle dynamometer. It was envisioned as a device to grab the temperature information from a couple of Dallas Semiconductor DS18x20 1-Wire® Thermometers and send the information to a serial port of a laptop computer for logging and subsequent graphing and analysis.
