From the list of ideas, we chose an occupancy sensor for the toilet. It is a real problem when you have only one toilet on the floor, because it is occupied almost every time you walk past it.
To solve “the toilet problem” we decided to create a simple, low-cost device that could check toilet occupancy and send info to Syncano (a backend for apps that has real-time modules already built in to allow you to easily get real-time updates).
Then, we could share data with colleagues so that they could build an app to let the next user know when the toilet is available.
Here is a list of parts that we used:
When you connect everything it should look like this:
If you have more questions about the hardware, or if you need help building a copy of this device, just let us know.
From this point, everything was ready to build the app to let the next user know when the toilet is available. We decided to go with a website that we could use to show info on one of the big screens on the open space. After one hour, the website was ready and the app was running on the big screen.
Another interesting thing is that using Syncano’s cloud feature you can trigger a script when the data changes. Let’s say that we have 10 sensors sending/receiving data and we would like to let them communicate together. Using the Syncano solution, we could do it in a really easy way. What’s most important is that we could easily re-program our system without touching the devices, because all of the scripts are on the backend side. So it’s a great communication tool for the Internet of Things.
More projects from our iot team soon :)
