"Adjustable" Infrared Sensor Switch, how to adjust?

Hello,

I've bought two [url=http://www.dfrobot.com/index.php?route=product/product&keyword=sen0019&category_id=0&description=1&model=1&product_id=114]IR sensors[/url].

Actually, I could see the small screw behind the sensor, but there is no mention on [url=http://www.dfrobot.com/wiki/index.php?title=Adjustable_Infrared_Sensor_Switch_%28SKU:SEN0019%29]the Wiki[/url]. I don't know if the default value is the right and what is the default range (meter/volt).

Could you explain me, please ?

Thanks :) Vincent14

The screw will set the sensitivity for the sensor anywhere from 3cm to 80cm. So you can just provide power to the sensor and adjust the screw to the desired distance by holding it at the distance you desire the sensor to activate at.

I hope you understand my meaning. The Arduino program will just detect if there is an open or close when the sensor is activated. Hector
