Need guidance in sourcing distance, proximity, thermal, etc

Hi guys,
Just started looking into Arduino and very happy with the open source and modules.
I'm looking at various sensors. If you could help with module part no# or descriptions, it would much appreciated
Here's a list:
A long distance sensor - a range of 1-8m, laser reflective or capacitance
A speed detector - not one for a rc motor, but a sensor that would detect larger objects eg. person and a range of 1-100m
A thermal detector - for detection of a human body's temperature.
Sorry, but I may add to list a bit later.
Thanks in advance

What is the budget ? thousands of dollars ? ten-thousands ?
Should it fit in a van ? or a suitcase ?

The Arduino is for fast prototyping. To connect a temperature sensor or accelerator sensors or digital compass, and to drive a few leds or relay. It is even possible to connect to the internet.

To measure the speed and temperature of someone at 100 meters, you need professional equipment. Perhaps military-grade equipment.

Thanks for the reply,
Though in looking for Arduino products, I wouldn't be looking at 1000's
On that, any suggestion would be great, I can then research adaptability in size.
I have looked at FLIR for thermal as an example,and not ruling that out.
Would like to test project functionality with a affordable kit first.
Has anyone had any success with modules exceeding thresholds other than the products specification?

Perhaps you should look at a platform capable of image processing. Like the Raspberry Pi or a mini computer.There is open source image handling and regcognition software.

A melexis temperature sensor can be connected to the Arduino, but that is about how far it gets. It can be attached to two servo motors to scan. After a while a picture can be created on the PC that shows for example the hot and cold spots of a house.
