A fine and cheap sonar for simple projects – Ultrasonic Sensor Distance Measuring Module Reviews

Pros:
I had my time with sonars and this one is cool one especially because of it's price and quality. The 4-pin design makes it clear how to use it without runtime pinmode switching (unlike the 3-pin sonars). It's nice in close-range measures.
Cons:
It's far from the stated measurement distance and the reading speed could also be faster. The 4-pin design can be a drawback when using a platform with a small number of pins.
Other:
Altough listed as a con, the reading speed is not a big trouble when using a lot of sensors since the controller itself doesn't have all time to read the sensors.
Bottomline:
Good price, also the discount possibility is really great. I'd recommend using them in hobby robots for detecting close-range obstacles.
