Hello, I have a problem with this sensor hall sensor ah543
http://www.ebay.co.uk/itm/5pcs-Unipolar-hall-effect-sensor-AH543-/290626927572.

I connected like this: NOTE: IT IS THE ah543, SAYS THERE BUT FOR OTHER SENSOR is the same for CONNECT

works well and is activated by passing a magnet.
but the problem is that if I run my hand closer than one meter from the sensor activates the same.
it may be happening? any solution?

Perhaps it is electrical noise at the digital input.
Try 1k or 4k7 for the resistor.

Try 100nF decoupling capacitor "near" the sensor between + an GND.
