5753L dectection range with different height ?

HI,

Can anyone show me of how to calculate the detection range of the 5753L 360 degree PIR Motion Sensor in terms of the mounting height ? Thanks.

 

The installation instructions for the product have a graph showing detection range relative to installation height.

Many thanks for your quick reply. I am interested in the maximum height of the 5753L can be mounted to detect 2m radius range.

Thanks again.

 

CY, am I right in thinking that you want to mount the PIR high up in a ceiling and detect an circular area of 2m dia directly below? Say in an enterence hallway etc? A better idea of what exactly you are trying to acheive may help get you useful responses.

As this is slightly different to the design requirements of the product I think you will find there is no ready made answer.

Rough tests indicsate that you will get ~ 1.5m dia coverage when the PIR is mounted at 3.3m hight (and I emphasise that these were done as part of tests for a different purpose under 'ideal' testing conditions - so actual detection range may vary when used in real life situations due to direction of movement, background temperature etc may vary - you really have to try this out yourself in the actual site to be sure).

 

Thanks UncleDick, message is clear. I will test the sensor at a height of 3.5m.
