Splash pad Q&A: sensors

Sensor-activated splash pads use motion or push-button sensors to trigger jets only when kids are present, conserving water and power. A typical install pairs PIR or radar motion sensors with a programmable logic controller that opens solenoid valves on demand for 5-15 minute play cycles.

A growing number of municipal splash pads stream live chlorine, pH, and ORP readings to a public or operator dashboard. Probes in the recirculation loop sample every few seconds and push data to a cloud platform, with automatic shutoff if readings drift out of range.

Yes — newer installations use overhead radar, infrared beam, or computer-vision cameras to count people on the pad in real time. Operators use the data to size jet pressure, trigger overflow protocols on busy days, and feed parent-facing crowd-level apps.

Yes — most modern splash pads include water-temperature, pavement-temperature, and ambient-air sensors. Data feeds the smart-flow controller for cold-weather lockouts, hot-pavement warnings, and seasonal scheduling. A few pads display live readings on a parent-facing kiosk or app.
