DIY Zigbee Water Level Sensor

So after reading some other users posts about Diy Zigbee sensors using the aqara door/window sensors I started thinking about what else I could do with one. Initially nothing crossed my mind until the water top of tank for my wife’s fish tank ran dry leading to the pump running dry for who knows how long. I then remembered that the cheap water level float sensors use two wires just like the diy sensors I had read about. I quickly ordered the parts on aliexpress and promptly forgot about my idea …

I will add my contribution to the list:)
