Embedded system - list of sensors

[Dusko]

My idea is on this place to exchange ideas, knowledge and links for sensors which can be used in embedded systems.

I will start with first:

System for identification:
================
sensor 1: RFID card
sensor 2: **broken link removed**

System for measure level of liquid:
======================
sensors for measure level of liquid (basics)

Sensors for measuring temperature:
========================

Temperature Sensor - The Thermistor
**broken link removed**

Sensor for measuring distance
===================
**broken link removed**
