Smart Hen Coop #ArduinoCloudGames2022

I have hens that are not at the same place as I live. They have an automatic door that can open and close on time I set, but the hens are living creatures, not machines. They sometimes don‘t get in in time. That means that I have to travel for about 15 minutes to the hen-coop, open the door manually and then travel back home. I thought there must be a better solution, something I can open/close not only in time but on my demand too. But there isn’t. Well, there wasn’t… Because I made the solution myself… behold the Smart Hen Coop! And it comes with far more than just opening and closing door at demand, it can turn on/off heater based on inside temperature, notify you when hen is possibly closed outside and also check if your automatic water feeder isn’t malfunctioning and oberflowing!

SENORS

Open/close door switch

I use micro switches to know if the doors are opened or closed

Movement sensor (PIR SENSOR)

Waterlevelsensor

In my case, the only problem I had was that the water in the automatic filling system could fail and I wanted it to notify me if it does, so I cut a hole the tank and put the soil oplá kit moisture sensor in. So when the water gets to it, it triggers.

Door servo

Temperature sensor

Unfortunately, I couldn’t find a photo of the temperature sensor I used

Relay

Now we connect everything according to the schematic

PCB

IoT Cloud setup

IFTTT Notifications (requires IFTTT Pro+)

First we create new applet and add webhook trigger with JSON payload to it.

Then we add what the trigger should do. I chose notification, but you can choose email and other things.

Then we add filter

and paste this to the filter code

var payLoad = JSON.parse(MakerWebhooks.jsonEvent.JsonPayload);
if (payLoad.value1 == "motionOutside"){
 if (payLoad.value2 == "Motion outside detected!"){
   IfNotifications.sendNotification.setMessage("Motion outside detected!")
 }else{
   IfNotifications.sendNotification.skip();
 }
}else if (payLoad.value1 == "waterOverFlow"){
 if (payLoad.value2 == "true" || payLoad.value2 == "1" || payLoad.value2 == "True" ){
   IfNotifications.sendNotification.setMessage("Water is overflowing!")
 }else{
   IfNotifications.sendNotification.skip();
 }
}else if (payLoad.value1 == "errorLog"){
 IfNotifications.sendNotification.setMessage("Error! Check errorLog!");
}else if (payLoad.value1 == "heatingState"){
 if (payLoad.value2 == "true" || payLoad.value2 == "1" || payLoad.value2 == "True" ){
   IfNotifications.sendNotification.setMessage("Heating turned on...")
 }else{
   IfNotifications.sendNotification.skip();
 }
}
else{
 IfNotifications.sendNotification.skip();
}

Then we continue and finish.

Now under the profile icon we click My services and find webhooks

Open the documentation.

We change the {event} in trigger with JSON payload to our trigger name and copy it.

Then we go back to Arduino IoT Cloud and click set webhook.

We paste there our link add it and thats it!

3D printed parts

Unfortunately, I couldn't find where I downloaded most of the models so adding it here without credit would be plagiatorism, but I'm sure you can find models that are right for you!

DASHBOARD

You have lots of options on the dashboard with this project, so make it yourself-friendly!
