Hi
Would the following be easy enough to do or are there any affordable products on the market to do it? Do you know of anyone who could help me do it?
The idea was to activate a motor to close a vent when sunlight fell on a light sensor or rain landed on a rain sensor. It would be good if the louver opens again when the light fades or when the rain sensor dries out. So when the sunlight was on the sensor or there is rain the motor would go forwards until it hits a limit switch to cut the power to the motor. I could simply wire in a micro switch to do this. When the light faded or rains sensor dried out, it would be good if the sensor caused the relay to put the motor in reverse. I thought that two circuits would be needed because if only one circuit is used, the limit switch would keep the circuit open so that even when the relay put it into reverse the limit switch would still be open. If one circuit is used it would have two limit switches on the one circuit where one would be closed but the other would be open. However, if two circuits are used with on limit switch on each of the circuits the SPDT relay would switch over to the reverse circuit where the limit switch would be closed to enable the vent to open.
Your help is appreciated, Regards Richard.
