Hi all,

I need help for school project. I want to make usb alarm with temperature, humidity and gas sensor. Which parts do i need to buy. I know i need board, but which one and what sensors.

thanx

Uno will do, can act as slave USB port to a PC (that is, you can send messages out, but you cannot control a USB memory stick (without more hardware)).
Search www.sparkfun.com for "sensor" they have a variety and some are sure to meet your requirements.

The term 'gas sensor' so vague as to be almost meaningless, and you've given no information about what sort of range, precision or environmental requirements you have for the other sensors. Once you know what you're trying to measure, you will need to do some research to see what sensors meets your requirements. For example searching for "Arduino humidity sensor" would give you hundreds of thousands of hits including worked examples using Arduino.
I only provide help via the forum - please do not contact me for private consultancy.

Figaro makes a complete line of different gas sensors, and these are sold by different
companies, such as Parallax and others.

I talking about>
FC-22-1 Harmful Gas Detector Sensor Module for Arduino
DS18B20 Digital Temperature Sensor Module for Arduino
Flame Fire Detector Sensor for Arduino board

which board i need to conect via usb to PC to read parametar

The Arduino UNO bds that CR mentioned connect to USB. You will probably want to use a
prototyping shield to wire up your sensors.

Well as lax says, the main site explains about the software which when you install will have a heap of sample code.

But along with the Arduino and sensors you'll need a means of protoyping the whole thing. As a minimum I'd suggest a breadboard and a box of jumpers. Get some LEDs and resistors too, so you can do at least some of the basic exercises before you dive in to the sensors. Maybe think about getting one of the starter packs which include various odds-and-ends.

You'll also need to consider power for your sensors: check to see if they can be powered from the Arduino and maybe get an external battery or other power pack.
