Instead f the relay can it be used a mosfet

Thanks
Also do yoy have a mosfet you would recommend to me?

Temperature, gyroscope, light, hall efect, atmospheric pressura

The Parallax Si1143 Proximity sensor has three points where it "senses" if i use one to turn on and off and the other two to the dimming (+ & -) would it be faster? Using the time to increase/decreases the light...

The relay could be a mosfet? Also can i dimmer the lights? Usig the pwn output would work? Maybe using the distance as the dimming value?

Hi everyone.
 I would like to make a sensing station to send values to a website through the ethernet shield. Does anyone know some sort of shield that incorporate various sensor? I am on a limited budget and i want to make the most out of it. I'm using an Arduino duemilanove with a ethernet shield on it and i'm waiting to buy the sensor shield. What would you advise me to buy?

Would the proximity sensor work with a grill in front of it? For design reasons. And could it be painted?  I want this to be an definitive solution.

ARD mini is fine, but look at the specs, I think one is 5 volts and the other is 3.3 volts. Most sensors use +5 volts, so make sure you know what  your getting.

The ultrasonic sensor look like it has 2 miniture cans on the front, and may protrude outwards. If you want something that be hidden easily, then go with the IR distance sensor. Both should work with the same code.
What ultrasonic sensor would you recommend?
Would a ARD micro work? And how to connect it to the lights? And power?

I believe one of these three sensors would work out. Wich one is the best? I chose the PING))) Ultrasonic Sensor, the PIR Sensor and the Si1143 Proximity Sensor. All of them from Parallax.

ok. do you have any parts already, the arduino, the sensor, some LEDs... anything?
Could you post a link of your exact sensor, that way we can see what you have.
I'm thinking about using a arduino mini, and I don't know yet what kind of sensor and I would like some advice.

I'm still working into making the project a reality, so I didn't start to write code yet.

I'd like to make an ultrasonic switch for my light bulbs.
What does this mean? Are you trying to get the lights to come on when you get close to them?

Quote
Since the ground wire passes through the switch, how would I use an ultrasonic sensor or something like that to make it work?
What switch does the ground wire pass through? Usually, the switch makes/breaks the hot wire, not the ground wire.

And would it need coding or a arduino?
Yes.
Like attaching the sensor to the wall and when I slide my hand it turns on, and when I slide my and again it turns off.
Sorry, got my electrical wiring knowledge a little mixed up.
What kind of arduino I need and others components?

And how much measurings (both Gyro and GPS) would a 10gb SD card would be able to save.   
How many buckets can my barrel hold? If you want to store one reading a day, you could probably store a couple of centuries worth of readings. Store more often and the duration goes down.

How you store the data matters. How much data you store matters. How often you store the data matters. In which file(s) you store the data matters.
2 readings a day, .text file, a line where's written time and coordinates.

Hello,

Obviously from my query; i am new at this. I need to have a PIR sensor, sensing a very general and rough count of people, then that count per a defined time interval (e.g 3 sec) will affect the output voltage. So the more people pass through a space, the higher the voltage (which in turn will activate another circuit).
I can not seem to find a code that combines all those features, specially one that generates the output i need.

Thank you for your time.


You should ask that at code forum.
