Egg Incubator with the PID controller corrects the shortcomings of conventional incubators that cause egg failure. This board is using simple components(through-hole components) and only 1 layer of PCB. It can be easier for anyone to assemble and produce.

A conventional Egg incubator is an egg incubator with a digital heater control. It will be turned on when the temperature reaches below the minimum threshold and it will be turned off when the temperature reaches above the maximum threshold. Unfortunately, after the heater is turned off sometimes the incubator temperature is still raising because of the imperfect incubator system, it also happens when the heater is turned off. It makes the incubator temperature not stable. The unstable temperature can cause egg failure.

I need to make a simple system that can resolve the conventional egg incubator problem. So I made Egg Incubator with PID Controller. My system is simple, it changes the digital heater system to the analog heater system. I use the PID controller to control the analog heater system. PID variables can change from the firmware or when the device is turned on. I use DHT22 for the temperature sensor to maintain accuracy. It also has a humidity sensor.
