Sensor hall-help

hola,  tengo un problema con este sensor  sensor hall ah543
http://www.ebay.co.uk/itm/5pcs-unipolar-hall-effect-sensor-ah543-/290626927572.

lo conectado asi:  nota: es el ah543  , ahi dice para otro sensor pero es  lo mismo  para conectar


funciona bien y se activa al pasar un iman.
pero el problema es que si paso la mano una distancia menor un metro  del sensor activa lo mismo.
que puede estar pasando? alguna solucion ?

prueba aumentar el valor de la resistencia.

saludos!
