Summary of DS1820 Temperature regulator using PIC16F628
This project implements a simple temperature regulator using a PIC16F628 microprocessor and a Dallas DS1820 one-wire temperature sensor. The system reads 9-bit centigrade data from the sensor via a single data line and ground. While the sensor supports parasite power, this specific design does not utilize it. A LED serves as an indicator for the fan status within the regulation loop.
Parts used in the Temperature regulator using PIC16F628:
- Dallas DS1820 one wire temperature sensor
- PIC16F628 microprocessor
- LED
This simple project uses a Dallas DS1820 one wire temperature sensor and a pic 16f628 microprocessor. A simple temperature regulator where a LED symbolizes the Fan.
Data derived from the DS18s20 is a 9bit centigrade temperature measurement. As mentioned the temperature sensor communicates over a one Wire bus that requires only one data line and ground for communication with a central microprocessor.
The DS18S20 can use power directly from the data line (parasite power) wich eliminates the need for an external power supply. This is not used in this project though.
