Irrigation Rain Shut-Off Sensors
A simple rain sensor wired to the irrigation controller prevents the most common landscape complaint: sprinklers running during or after rain. SMPC supplies hygroscopic-disc and tipping-bucket sensors in wired and wireless variants, all compatible with standard zone controllers.
Types & Variants
| Type | Description |
|---|---|
| Wired Hygroscopic-Disc Sensor | Compact discs that swell when wet, opening a switch contact to disable irrigation. Reset themselves as they dry. |
| Wireless Rain Sensor | Battery-powered RF rain sensors for retrofit on existing systems — no need to run wire from roof to controller. |
| Rain + Freeze Sensor | Combination units (where freeze protection matters — generally export market) that suspend irrigation on rain or low temperatures. |
