This is a 44E hall sensor. Simple to connect and use with Arduino/Genuino projects. The 3 connectors are GND (-), VCC 5v (in the middle without label) and signal. From testing this sensor it seems to be quite digital, so reading nearly high value when no magnetic field is close to the sensor, dropping to low (ground) when magnet is coming close to sensor (distance 10-12mm). Please note the sensor will only react to north of the magnet, so make sure to use it in the right direction. When magnetic field is strong enough, a small LED will light green and signal drop to low.

Pros: Quite easy to figure out without any documentation, all the pins are either well-labeled or obvious. Good quality for the price.Also it is really small so it could be hidden if you wanted to. Cons: None that I can think of... Work right away and compatible with arduino, mbed and all kind of other mircocontroller boards. I don't have any cons till now and I can not think of any. Especially for this price!!! Other: Easy to interface to my Arduino, good deal. I will recommend this to friends.
