DS1820

Multitherm

16. September 2008 - 18:04 — admin

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.

Thermometer with DS1820 + ATtiny15

This is my very first construction with the cheap Atmel's ATtiny15 and the DS1820 thermometer. The main goal was the BIG display from the 7-segment LED modules. (And cheap + simple construction, of course...)
