raspberrypi-incubator
Software for controlling the temperature and humidity of an incubator using a Raspberry Pi.
This project uses a Raspberry Pi together with an AM2315 temperature/humidity sensor and a MCP4725 DAC connected to its I2C bus to measure and control the environment in an incubator.
There is a web interface to show a graph of the most recent data (together with average values and standard deviation) and change the wanted temperature and humidity levels.
The master branch should always be in a stable state. Development takes place in the develop branch and all feature/* branches. The current stable version is 0.4.5.
Feel free to send me a pull request if you have anything to contribute.
Installation
-
Get libmicrohttpd and zlib for your RPi.
-
Adjust the values in include/config.h.
-
Change the script source in html/root.html if you want to modify the javascript and/or host it on your own server.
-
Set the CROSSROOT variable in the first line of the Makefile. This variable defines where the build process will look for the headers. If you have a compiler on your RPi, you can simply use /usr/ here.
-
Run make (don't forget to set CC if you're using a crosscompiler).
-
Copy js/* to your webserver (if you're using your own) and main and html/root.html (as 'roottemplate') to your RPi.
-
Run main in the same directory where you copied your root.html. It should start printing its log data to the standard output.
Todo
-
The control part is not actually done yet, but will use a 1 ohm resistor on the DAC to increase the temperature and most likely an ultrasonic fogger over a relay connected to a GPIO pin for the humidity control.
-
Maybe a webcam with motion detection for when the eggs start hatching?
-
Right now, the javascript is served over an external page. Maybe have the builtin httpd handle that. If you don't have a httpd, you may either install one on the Raspberry Pi, or copy the contents of js/graph.js into html/root.html.
-
src/httpd.c could probably use a bit of refactoring...
-
Change user/password through the web interface, and store them.
