2 channel LM35DZ temperature sensor project
This is quite simple temperature measuring unit which uses two LM35DZ sensors, Atmel AVR AT90S4433 (now obsolete) which is compatible to Atmega8. Information is displayed on standard LCD and optionally sent to RS232 port.
Circuit diagram of temperature sensor is here. C files are available in site. Site originally is written in Japanese language, so use a translator.
