Window Control with Temperature and Humidity Sensor
Created: Feb 05, 2017
This is the circuit for a controller of an electric window opener.
The window opener is driver by main power. It has three wires and is powered by 220V AC (german main). The wires are a common neutral and two line wires. The line wires shall be driven mutual exclusive to open or close the window. The internal electronics of the window opener do the detection of end states and/or blockages of the window. So this is not the job of this board.
In the circuit is a relais module which has two relais driven by 5V and controlled via two opto-coupled inputs. Each relais has a toggle switch. The relais power the window opener.
