Brief describition and Features of the Temperature Data Logger

Here's a temperature data logger circuit, an 8-pin microcontroller based circuit for temperature data logging via the serial port of any computer from between 1 and 4 remote digital temperature sensors, DS1820/DS18S20 made by Dallas.

Features of the Temperature Data Logger are are follow:

• Provides realtime data via the serial port.
• Interfaces up to 4 x DS1820 sensors.
• Accuracy to 0.5 degrees centigrade
• Fahrenheit scale selected by a jumper
• No external power required
• Data stream easily logged & processed.
• Over 200m distance for each sensor
