 Weather cover for the PIR sensor plus some thoughts about solar charging.

For the weather cover we are using a sweets container lol

Garden Sentry 12V - Part 6

 From Part 6 yesterday we are now doing some modifications and tidying up the wiring.

Decided to move the unit down the support post a bit further away from the sensor to reduce the likelihood of top overspray triggering the sensor.

Garden Sentry 12V - Part 5B

 In this session were doing the electrical wiring.

Wiring is fairly easy the only thing to keep in mind is that the PIR sensor has a negative switched output - a bit weird.

Mounting the water solenoid with irrigation fittings.

In the previous session we made the spacer block and here just drilled two holes for cable ties that will secure the assembly.
