What’s your favorite type of sensor?

Arduino’s are great devices because they let us sense our environment around us. There are a great number of sensors available that can work with the arduino. Digital sensors allow us to sense whether something is on, or off, like a door switch. Analog sensors allow us to sense how much of something exists, like how much light, or pressure. Some sensors give us actual data streams, like a gps sensor, instead of simple on/off, or a varying voltage.
