Do It Yourself - Water Depth Activated Relay Switch, Soldering Kit.
This kit will requires you to solder the components together to get a functional water depth relay switch. The way this board will function after successful soldering is listed as the following:
- Probe A or H, is the maximum fluid depth.
- Probe C or M, is the minimum fluid depth.
- Probe B or L, is the current fluid depth.
When probe b is below probe a the relay will be in "ON" state, when the probe b is at probe a it will be in "OFF" state and when the probe b goes down to c it will restart to "ON" state.
You can connect any device you wish that is rated below 10A at 250V AC or 10A 30V DC to the relay terminal blocks.
