im doing my s5 ece n my class in charge has asked me to do a project for our department some of our ideas are<br />
1.mobile phone power consumption meter(to measure power consumed by a mobile phone)<br />
2.automatic power cut off-detects the presence of people in a room and if room is empty the power to that room is cut off<br />
3.automatic flush in bathrooms using sensors<br />
4.wireless noticeboard with mobile phone feeds enabled
pls post if anyone has any knowledge or ideas about the topics mentioned above...plssss...

 

no ideas here....
unless u come up with something..no one here is doing ur homework 4 u

1) look at sparkfun and get one of their current sensor breakouts, build a voltage sensor with your microcontroller and then put that between the battery and the phone.

2) get a motion sensor from sparkfun then use your microcontroller to turn off power, using a relay, when there's no motion for 5 minutes.

 

#3 Use short range object detector, IR-photo transistor, beam break, etc, & gear head motor to lift flapper using crank and connecting rod.

From what I have seen, a solenoid valve in the filling line to an auto-flushing cistern is more usual. These things are sometimes retro-fitted to reduce water consumption.

 

I often wonder what the automatic flush circuits I see in stores are looking at. I assume the IR signature of my assets.

Assets ?

Bill it is nice to know, and need to know topics. I think what ever that will pas over the sensors are strictly in the need to know category.
