These are entirely two different types of sensors. IR sensor detects the transmitted infrared waves hence used for projects like a Line follower or cl...

Be it any sensor, you need some sort of processor to read its data and perform certain operations. Arduino does this exact job here.

HiTo start a measurement, the sensor needs a trigger pulse, which is a short, 10-microsecond pulse sent to the 'Trig' pin of the sensor. This pulse ac...
