====== Sensors, an overview ======

The idea is to give examples for a variety of available sensors.\\
To measure time, temperature, pressure, magnetism, distance, light level, etc.

  * [[en:pfw:measuring-distance|Measuring distances]], using ultrasonic and other sensors.\\

  * [[en:pfw:reflection-sensors|Reflection sensors]], a sensor that uses (infrared) light to detect the presence of an object.

**Some examples**
