This chapter describes the interfacing of analog and digital sensors with an
Arduino board. The sensor is a device which detects the change in physical, electrical
or other parameters and generates an electrical or optical signal as output. The sensor
which produces a continuous output signal is known as an analog sensor and the sensor
which changes the output status on occurrence of an event is called the digital sensor.
The voltage of an output signal of an analog sensor is proportional to the quantity
measured. The examples of the digital sensor include capacitive touch proximity
sensor, and fire sensor and the analog sensors are voltage sensor, and current sensor.
