I had a look to Ultrasonic distance Sensor HC-SR04, it seems the best choice for under 4m distances.
Just bought a bunch of super cheap HC-SR04... hope they all work 😄
I successfully tested the five HC-SR04 Ultrasonic sensors, and I'm happy to say they're all working fine in a 4-380cm with a very slight deviation. For the task I made use of the NewPing library as it allows to measure distances in a non-blocking way (pulseIn is easier, but blocking), and an Arduino Mega 2560R3 Board.
The quadcopter is going to need environment distance measurements. Therefore, we need to gather information, and get some distance sensors.
