9V 12V AC DC Liquid Water Level Controller Detection Sensor Relay Module
No instruction? Don't know how to wire 9v-12v setup?
I bought two and of course they didn't come with instruction. No instruction and images with poor English on Amazon, eBay, Banggood, Alibaba, or whatever.
Took me several searches on Google to finally find the answer.
This small module works WITHOUT Arduino! NO CODING REQUIRED. Three things you needs:
Power source (9V-12V)
Wires
Pump, LED, or whatever
I hope to use it for my birdbaths so I don't need to go outside and check for water EVERYDAY. I will also use SOLAR PANELS to run them.
-----------------------
9V Battery - Yes it works but I doubt it would last long enough. Would be better if you used a 3.7v 18650 battery with buck / step up converter (boost to 9v-12v).
Повторяем попытку...
