Motion sprinkler 12V version
Garden Sentry problems
Garden Sentry – problem :-(
Went out last night to turn on the garden tap and check the motion activated sprinkler and discovered the system has a problem. The PIR sensor turns on and stays on? Gave up after stuffing around for a while and shut everything down.
Garden Sentry spray shield modification
Adding a spray shield to the motion activated sprinkler.
Without something like this the over spray will keep activating the sensor and the system won’t turn off.

At 3.45am this morning a very surprised prowling cat was detected and scared away with noise and water spray!
Garden Sentry update

No prowling cats the last two mornings so here we setting up for tomorrow morning – under cover.
Unexpected rain and thunder this afternoon so had to run out and being the equipment in under cover and yes… working on weather shields.
Garden Sentry enhancements
Made a box to hold the sensor unit and now making a base support for the timber stand.
