Since decoration in new office is ongoing (photos will be posted later), we have to use a water tank to receive the water from air conditions. It will fill up about every hour, and needs manually emptied. It’s OK as a precious exercise, but the water fill speed is a bit random, we set up a water level alarm like this:
The device itself is a waste, not including the time we spent programming. Instead of bothering with USB cable, adapter, computer, IDE, compiling error… Can we make an “If…then…” hardware similar to ifttt.com?
We are providing Grove system, a whole collection of quick prototyping sensors and actuators. What’s needed is a hub module like “Stem” with one connector as “condition” and another as “execution” . The condition threshold is set by “learning”, and the execution output is decided by a potentiometer. Adhering the above example, you just need to set the output volume, immerse the water sensor while pressing “learn” button. Programming done and ready to use.
To apply more complex functions like delay and loop, we could add a light sensor to this stem, so you can use some APP on your smartphone, do some simple tinkering, then use the flash light to program the “Stem”.
Just some thoughts, would you be interested in helping this project? Especially on the App part. 🙂
