laser or InfraRed?
So, my Automated Chicken Coop is going well. In other posts on this forum i hhave discussed the automated doors and lighting with LED's etc.
These are running very well and are saving lots of time and effort.
My next upgrade will be to automated the feed.
I am quite keen to utilise either infrared or lasers to do the following.
Imagine if you will a storage container with two lasers/infrared sensors. One near the top the other near to the bottom.
When the bottom beam is open or unbroken then this will turn a servo, opening a butterfly valve to allow feed to drop. when the the top beam is broken and the feed has reached the required max then the valve closes.
This system is used on our boimass boiler to fill the hopper with wood chip before it gets dragged via an auger into the furnace side.
Any advice on which route to go down would be appreciated as would tips on the right components/tutorials etc.
My first thougts are to use a laser shining onto a photoresistor and calculate the differences in the values of the laser light hitting it and when its blocked by feed to define when the motor open and closes the valve.
I know there will be a multitude of different ways to acheive the same goal. I just think this way is quite aethestically pleasing.
