I run a FabLab and we are planning to hold a class called Raspberry Pi and Cayenne - the perfect recipe for IoT. We need to come up with a good project that students can complete in a few days. Fly fishing is really big around here, perhaps we could develop a project that notifies you on your smartphone if the fish are biting Hhhmmmm…what kind of sensor integration would we need for that?
Maybe we should start with something easier. I have connected up a BMP180 and a LED to the Pi. Configured the temp and pressure aspects of the sensor and have them displaying properly. I added the Light Switch and set up a trigger so that if the temperature exceeded 80deg F the light would turn on. Added a second trigger to turn the light off when the temp dropped below 80deg F. All of that is working good. Hooray!
I understand the BMP180 also has an altitude sensor? But I don’t see that as an option when I go to configure it.
Also, the pressure is reporting in pascals. Can we get the units reporting in/Hg?
