But here''s the problem: Arduino can''t provide enough power to run this sensor from its pins sensor''s heater requires 150 mA, while Arduino pin can provide no more than 40 mA, so if attached directly, Arduino pin will burn and sensor still won''t work. So we must use some kind of current amplifier that takes small input current to control large output current.

While the Arduino''s 5V power is theoretically able to power the K30, the sensor needs 300mA minimum to operate the light inside the sensor. The problem is, if you power the Arduino from your PC''s USB port, the K30 has to share power with the Arduino, your mouse, and any other devices on the USB bus. The power to the sensor will drop under 300mA, and it won''t operate properly.

20191028· The Arduino has a 10bit AnalogtoDigitalConverter (ADC), which maps sensor readings between 0 and the operating voltage (5V or ) into integer values between 0 and 1023. This is derived using the calculation 2^10 = 1024, so the range ends up being 01023. The resolution of an Arduino is about per unit (5/1024 = or ).
