Hi all.
For my university project I am making a simple heron/cat deterent for a garden fishpond. (A sensor detects the pests and fires water)
I have a P.I.R Sensor with a built in relay, and I have a 12V water pump out of a car windscreen washer system.
The pump and sensor work fine. My problem is getting the pump to work when the P.I.R Sensor detects something.
I have wired the pump to a 12v battery which is connected to the built in relay of the P.I.R sensor. I can hear the relay clicking but the pump doesnt start. I was advised I may need another relay. Can someone suggest what relay I need and where I could get one from?
Info
On the P.I.R. sensor leaflet is says:
Relay output: 0.2A/28V with 15ohm resistor
