Join Michael Lehman for an in-depth discussion in this video Understanding sensors, part of Android App Development: Internet of Things.
- As we talked about earlier,…every internet of things device…consists of four basic things.…Sensors and/or effectors, compute capability,…and connectivity.…So let's talk about sensors.…Sensors are the devices that allow you to connect up…real world inputs into your thing.…They can measure things that are in the environmental space,…temperature, humidity, pressure, flame, smoke.…They can measure motion of a variety of different kinds.…They can measure motion in a room with IR.…
It can measure motion with ultrasound…by bouncing sound off the walls.…It can measure motion to determine…whether something has actually had…a significant enough shock.…If you have a product that's marked fragile…and you put a sensor on it,…you can make sure that it's never been dropped…between the time you shipped it…and the time the person at the other end receives it…and of course you could even hook up a GPS to it…so that you could know exactly every step it traveled…between here and there.…You can sense a number of things with light.…
