Chicken door

#1 Post by TungstenE2 » 14 May 2018, 13:20

Hi all,

I am planning to build an automated chicken door, based on Wemos D1 mini.

Currently I am in the planning phase and creating shopping list.

Which motor and motorshield is recommended to work with ESPeasy and D1 mini?

I would like to operate the door by:
- light sensor and/or time
- manual button pressing
- mobile

Magnetic reed sensor should identify the endpoints.

Has anyone done this already on ESPeasy and has some ideas/tipps for me?

thx

You can make just about any motor work with ESPEasy. Just a matter of the correct relay setup and such. Same with limit/position switches.
The big question here is the actual door hardware to use. What kind of door? How big is it?
These are questions you must answer B4 we can recommend much.

thx for your reply.
door will not be heavy. size 25x15cm. I assume it will be from plastic.

Would like to use the Wemos motorshield, but there is no plugin for this available at the moment.

For position switch I just odered reed contacts.

I've made a ckicken house recently.
As the roof was ready, i had the idea to use an old solar panel. So i've rebuilt it, but the dimensions of the house did not fit...
Anyway, this opens so many opportunities (self-sufficient door, camera, light, rfid, ...) that i'm glad i did it.

Instead of a motor shield, i just used 2 relais.
The door is controlled according to sunrise and sunset (and manual).
Currently there are no end switches (only runtime based), but i will change that in the next days.

This is the motor (3rpm):

I bought a motor with 80rpm. hopping it is not too fast...

The rpm depends on the voltage - also, it's stronger the less rpm it makes. And i didnt want to behead the chickens :)

Before building, i've made a rough plan, to estimate space and material better (yellow means removable).

Having raised chickens, I don't think the plastic door is heavy enough for that, but I would not put it past a chicken to put their head in the door as it closes. ;)
They are not the brightest of animals.

Years ago we had a TV with automatic doors which opened or closed when you turned it on or off. It used a very simple motor driven cable system with "limit" switches. The limit stitches were simple spring loaded lever switches and a nuts/bolts on the cable. When the door closed, the nut/bolt hit the switch and turned the motor off, protecting it from running until it burned out. Same on opening. Easily adjustable, just move the nut/bolt a little.

The design in the picture is pretty good, but I would think about a sensor in a side so it will report if the door itself is not closed when it is supposed to be.
Opening and closing can be triggered by a daylight sensor, you just need to have an adjustable light level and wait a few minutes after your sundown. Not too long or you risk something looking for a snack. We had problems with foxes, bobcats, Owls and a really stupid snake which fit through the chicken wire until it ate a few chicks and could not get back out.

Also keep in mind chicken crap is extremely corrosive and if I remember correctly will kill off any plant life for several years. But it is a good fertilizer after something like 5 years.
