or "SENSORS?"
or "EVEN MORE SENSORS?"
1.The elevator's got one that keeps it from moving while the door is not quite closed right. It is missing the one that keeps it from closing on you and your bike though.
2.The one on the hot chocolate machine is pretty excellent, you fill it 2/3rds then let go of the button and it fills the rest up for optimal cocoa:water ratios. (yum)
3. There is a nifty little light on the inside of the Frigidaire that turns on and off when you open and close the door. (open the refrigerator, close the refrigerator)
4. The butterfly species clock in our room makes butterfly sounds (???) on the hour only when it is not dark in the room.
5. Smoke alarms detect burning popcorn within 3 minutes of ignition!
6. Thermostats make use of bi-metal strips to detect changes in temperature.
7. bikes use simple mechanical "sensors" to operate breaks. (they are so totally pressure sensors)
8. Automatic doors detect motion so they only open when people are there and keep the hot air in mostly.
9. Motion sensors on light switches do similar, for the purpose of saving electricity.
10.Touch pads use resistance sensors (somehow!) to detect where your hands are, and that is why sliding your pen around on it is not the same as your fingers because they are not conductive in the same way.
