Automate the opening and closing of solenoid valves for intelligent multi-tank water distribution. Perfect for scenarios where a single pump feeds multiple overhead tanks — HydroSmart-SO ensures each tank fills to the right level without overflow or manual intervention.
Ideal Use Case
In many apartments and buildings, a single pump supplies water to multiple overhead tanks across different wings or floors. Without automated valve control, filling each tank requires manual monitoring. HydroSmart-SO solves this by automatically opening and closing solenoid valves based on individual tank levels — ensuring efficient, sequential, and overflow-free filling.
How It Works
HydroSmart-L sensor detects low water in Tank 1
HydroSmart-SO opens Valve 1 to allow water flow
Tank 1 fills while other valves remain closed
When full, Valve 1 closes and next tank begins
What's in the Box
Relay-based solenoid driver
Controller power supply
Solenoid valve power
Connection Architecture
Each HydroSmart-SO controller connects to exactly one solenoid valve. For multiple valves, you need multiple controllers — this ensures dedicated, reliable control for each valve.
Add as many valve controllers as needed for your multi-tank system. All controllers communicate wirelessly via LoRa to the central HydroSmart ecosystem.
Controller: 5V DC | Solenoid Valve: 12V DC
