New Hall Sensor Module for Arduino (Works with Official Arduino Boards)

Pros: Straightforward operation - no instructions required. Can be used with or without Arduino. Digital output interfaces directly with TTL or CMOS logic circuits. Small footprint with optional bolt to anchor. No soldering required. Pins have standard .1" (2.54mm) spacing. Two LEDs onboard. One to indicate power, the other indicates the state of the switch.

Cons: The only minor negative for my application is that that the pins add significantly to the height of the circuit board. I would prefer that the pins had the 90 degree bend to come parallel to the board instead of perpendicular. But that's an easy fix.

Other: Well worth the price. Better than building my own. Very easy to use. I want more of these.

Pros: Might be very nice for a home project with your arduino board. The quality is really nice, for the price I couldn't imagine such a nice product. If you need it, buy it.

Cons: Couldn't find many usefulness, maybe when I have many projects I can tell, but till now I think it is not that useful. But it was cheap and it's here, if I need I use.

Other: If you know how to use and for what you should use, purchase it, otherwise, you can purchase it too, it's too cheap!
