PID Thermostat Controller with bult in AC dimmerAuthor
Hercules Trapierakis
February 24, 2012

This is an PID thermostat controller with built in ac dimmer for resistive loads and Sd-card datalloging support

The purpose of this is to used as an incubator controller

Its based on the ATmega8 of Atmel

The Sensors are the 1-Wire DS18B20 thermometers from Maxim

It features:

-PID controll
-2 external measuring thermometers
-Auto measurement the AC mains frequency to adjust the dimmer parameters
-Soft start of the load ( perfect responce with non-inverter gas powered generators )
-Datalloging on SD card ( Not ready yet )

    • Greetings, congratulations on the project, I would like to experiment with this design but do not get the atmega328, I only get the atmega8 or ATmega88, too much to ask that you compile the program for one of these microcontrollers, Thanks.

    • i just use a mercury thermostat, tilted at an angle to compensate for the higher temperature required for incubation. now a timed egg roller is something i would be interested in.

    • Are there any PCB design files for this project ?

    • HI hi

      I did somthing very similar, i tested it with a light bulb that dims
      Just a quick question, i would like to read this "controlled wavform" back into a plc/labview. How would you suggest this be done ?

    • @Hercules Trapierakis you've turned your parrot into a carnivore!!! DAMN

    • @Panagiotis Kalogeris

      This is George


      there are not to many eggs

      it's not even half filled

      Not but you can use it here and on America without change the firmware

    • Hello hercules nice project of yours!!!!!!!
      First of all what you intend to do so many birds?Hope to sell them because believe me i have 2 parrots and the one of it is a REAL PAIN IN THE ASS!!!!!Fantastic pcb did you develop it by yourself?Also you say that the circuit reads the ac frequency and it sets the dimmer parameters accordinally.Why is that?I mean the mains frequency isn't stable to your house?

      That's for start keep going :-) !!!!!!!!!!!!

    • @herctrap poor bird...
      You did not have something to do with the explosion,,,, did you???

    • yes i have changed the lamps from 40W to 60W

      The main power transformer near my house blown up two days before the incubation

      so the bird died from the cold

    • Herctrap, the writeup is excellent and the PCBs are awesome! The only thing that i am afraid of is this "overkill" temperament of yours... I hope you have installed the correct heating lamps, and that the birds that will come to life will not be roasted :D You did not change the lamps that your grandfather installed, did you :D

      What happened with the single egg incubator project? Will you develop the first "chicken of the tube" or not?
