DS1820 Temperature Sensor Readout Unit
This can measure temperature from up at 8 DS1820 digital temperature sensors all on the same 1-wire bus. That’s right only 3 wires are needed to go to all the temperature sensors, GND, VCC and 1-wire data. All sensors will connect to the same cable.Measure temperatures in multiple locations , no calibration required ,range -55 to +125Deg C,,log up to 8 temperatures to a PC using RS232.This project use AVR AT90S2312.
