I am thinking about building a fully automatic egg incubator.
Humidity, temperature, fresh air and egg turning should at least be controlled.
2 AI - One for humiditysensor and one for potentiometer (setpoint - Scaled to 0-100%Rh)
2 DI - one for automatic control and one for heatelement always on.
1 DO - For heatelement
2 AI - One for temperaturesensor and one for potentiometer (setpoint - Scaled to 15c to 50c)
4 DI - one for automatic control and one for heatelement always on. One for fancontrol auto and one for fan always on.
2 DO - For heatelement and fan
2 AI - for potentiometers (setpoints for time between freshairventilation and time for fan runtime - scaled 0-24 hours and 0-60 min.)
2 DI - one for automatic control on and one for always on.
1 DO - for fan
2 AI - for potentiometers (setpoints for time between turnings and time one turn must take)
6 DI - one for automatic turning on, one for tray down, one for tray center, one for tray top, one for move up and one for move down
2 DO - one for motor up and one for motor down
PV and SP should be represented on a LCD-screen.
AI = analog input
DI = digital input
DO = digital output
SP = setpoint
PV = process value
What controller and what sensors would you use? Is it at all possible to make this? The temperature and humidity should be controlled with PID.
I'm not a arduino-expert, should there be a Danish programmer who needs a challenge, dont hesitate to respond!
