Sensors are a vital part of a Arduino Project. A Sensor can be a simple end-switch, or an intelligent sensor board which precomputes readings for you. An analog sensor is usually read with an voltage divider. Most sensors relate the physical reading into and change in resistance. Like simple PT100 Temperature Sensors.

Distance Sensors

Distance sensors measure the distance mostly by light, radar or ultrasound.

Environmental Sensors

With environment sensors you can measure everything around you. Light Intensity, Humidty, Temperature and so on.

Miscellaneous Sensors

All other Sensors that fit not quite in another category.
