Pictured below is an automatic controller for a poultry incubator. The eggs in this incubator must be kept within a tightly regulated temperature range, they need to be automatically turned at regular intervals, and there is also a fan to be controlled.
The owner of this incubator would like the temperature of the eggs to be kept between 37 and 37.5 degrees Celcius, so there is a heating element which is switched by an on board relay following the temperatures measured by a DS18B20 waterproof sensor.
The eggs are to be turned every 30,45,60, or 75 minutes, and to do this the motor must run each time for a few seconds. Both of these timing intervals can be set by the user.
The fan has three modes of operation – on, off, or automatic, and in automatic mode the user can select an interval of 5, 10, or 15, etc minutes on and minutes off repeating.
