Increasing sensitivity with X10-ActiveEye MS16A

I have come across mods and schematics for decreasing sensitivity for

both The EagleEye ?MS12A and The HawkEye ? MS14A Most people want to reduce false alarms.

But no where can I find info on ?increasing? sensitivity.

The only thing that I found that seemed reasonable was the following

for the MS14A.

I?m assuming that this recommended PIR component (RE46B ) would be compatible with the MS16A.

I?m just wondering if anyone here may know why over a 3-4 month

period, My X10 motion sensor?s sensitivity level has degraded. It?s not the batteries, they have been changed and both measure at

1.54v.

I know that they work, because a large body passing the sensor, does

send the signal. I am trying to detect small animals, as it once did.

If anyone has any comments or suggestions, I could sure use any

feedback.

Thanks

Ambient temperature affects a PIR's ability to detect motion. The closer a body's temperature is to the ambient, the harder it is for a PIR to detect that body. I suspect nothing's changed in your ActiveEye - the difference is probably in the environment it's working in.
