For most of us, the only temperature we really care about is how hot the environment is around us. For better or worse, this means spending much of our time inside temperature controlled bubbles known as “houses” or “buildings.” If, however, you have other non-human biological entities to take care of, such as plants or eggs, very accurate control of temperature and humidity can be very useful.
Alex Borisevich’s incubator takes care of this using proportional-integral (PI) or on/off control (or a combination of the two) to regulate temperature using a heater. It also can regulate humidity via simple on/off control and even has a timer that can be used to rotate eggs. In addition to all of that, if things do get out of wack for whatever reason, the device has a buzzer to let you know that something is amiss.
It uses an Android app for control, which you’re encouraged to download and try before purchasing anything so you know it will work with your device. You can see the setup “in action” below. Though the video may seem somewhat long and uneventful, I suppose that’s what you want in a device meant to keep something at a constant temperature. Just after 5:00 is impressive though, when, according to the app, it’s able to maintain a 35 degree Celsius temperature to within plus or minus .01 degree!
