Why is the PNP Ultrasonic sensor better than the Polaroid ultrasonic sensor?
The biggest reason: Because the PNP sensor requires “no code” to get up and running. It’s very easy to use!!! All you do is just read the analog port and that’s it!!! (With the Polaroid Sensor, first you have tell the polaroid sensor to send out a sonar pulse, then you have to WAIT and keep track of the time VERY CAREFULLY until the sonar pulse comes back. This wastes processor time and is only as accurate as your code.) As a bonus, the PNP requires less space and is all in one package.
