S4 Water Detector Sensor

S4 Beacon is a small water sensor Beacon with ultra low power chipset nRF52 series and Bluetooth® LE 5.0 technology .

S4 has built-in water detection sensor, it can detect whether it is immersed in water in real time. When water immersion is detected, it will send alert to the system. It supports manual adjustment of the water immersion detection height to prevent false alerts caused by a small amount of water such as mopping the floor.

S4 water sensor can be used in places like hotels, nursing homes, industrial manufacturing places, etc.

HOW IT WORK

Once S4 water sensor detects water immersion, Bluetooth advertisement will be triggered.

The gateway receive the advertisement and upload to cloud server, the cloud server response and take actions accordingly, for example, send notification to management center.

PRODUCT APPLICATION

Water Leak Detection
The S4 Water Leakage Detector can be placed in kitchens, bathrooms, or near water pipes to detect water leaks in real time. Once water is detected, it sends a BLE alert to a nearby gateway, allowing the connected monitoring system to notify users and help prevent potential water damage.
Warehouse Water Leakage Monitoring
Water leaks in warehouses can damage stored goods and cause costly losses. The S4 can be installed in leak-prone areas to monitor water accumulation. When a leak is detected, an alert is transmitted through a BLE gateway to the management system, enabling staff to take timely action and protect valuable inventory.
Server Room & Data Center Protection
Water leaks from air conditioning systems, cooling pipes, or other sources can pose serious risks to sensitive IT equipment. The S4 provides continuous water leakage monitoring in server rooms and data centers. When water is detected, it triggers a BLE alert that can be forwarded to the monitoring system, helping maintenance teams respond quickly and minimize equipment damage and downtime.
