Protection from blackout.

If power is switched off.

This issue is especially topical in the countryside. Without heating almost all eggs will die in 12 hours. Before, when power had been switched off, I heated a brick on the stove and put it into the incubator. But I had to see to the temperature to avoid overheating. And it is very tiring. At the moment I have got a car battery, a 40 watt car bulb, a 220 V relay and the terminals that can stand the 5 À current.

I concatenated all this, connected the relay to the wall outlet. Now, in case of blackout, the bulb is switched on. It does not provide the necessary temperature, but the temperature in the incubator does not sink too much and embryos do not die within approximately the day and night period. If the incubator is big, two car bulbs can be connected in parallel.
