What are input device.

An input device is any hardware device that sends data to a computer, allowing you to interact with and control the computer.In this assignment I introduce some SENSOR as an input.the sensors is an hardware moat of the sensor having the 3 pin out mainly vcc,gnd and signal pin.

i use the following sensor with aurdino but i had made my final project input board with solar panel as sensor i used it in this assignment for input device

so firstly i explain these all sensor how work and what is the purpose of that sensor and working with aurdino

then i explain my input board

1.Input devices

A sensor is a device that detects and responds to some type of input from the physical environment.in above diagrame there are many sensors like temp.,humidity,ldr,soil moiture,air quality sensor,co sensor,switch. I go throgh the all sensor with aurdino.
