Explanation:
Detailed explanation-1: -Sensors are another type of input that can be connected to the Raspberry Pi. They may gather data about, for example, light or temperature conditions, but fundamentally they work in a similar way to the push button: they provide different input to the Pi depending on something that is happening externally.
Detailed explanation-2: -There are about 26 GPIO pins on the RPi 2, so you can get 26 sensors at least. However, remember that the Dallas one-wire sensors such as the DS18B20 allow several of the same device to be connected to the same pin. They use an in-built serial number to distinguish devices.
