Milesight EM300-SLD/ZLD Water Leak Detection Sensor
The Milesight EM300 Sensors offer reliable performance to detect presence of water or other liquids, these leak detection sensors are available in two different variants to suit your installation environments. The EM300-SLD water leak sensor has a probe attachment, whereas the EM300-ZLD is a rope sensor.
Ideal for applications such as hospitals, warehouses and server rooms, using LoRaWAN® to detect water leaks can help to prevent costly damages to your premises and equipment.
- Probe and Rope Type Available
- IP67 Waterproof & UV Resistance
- 10 Year Battery Life
- Embedded Temperature & Humidity Sensors
Milesight EM300-SLD Product Description & Topology
EM300-SLD is a compact spot leakage detection sensor for detecting presence of water (or other conducting liquids) and transmitting alarm using LoRaWAN® technology. In addition to LoRaWAN® technology with low power consumption, it has a built-in high-capacity battery available for several years without replacement. Combining with Milesight LoRaWAN® gateway, users can manage all sensor data remotely. EM300 SLD also integrates temperature and humidity sensors, which has a great use for applications such as pipe leakage monitoring, basement flooding, pump failure, etc.
Features
- Detect the presence of liquids by a small water probe and based on the conductive principle
- Embedded with temperature and humidity sensors for environment monitoring
- Ultra-wide-distance transmission up to line of sight of 10km
- IP67 UV-resistant and waterproof enclosure for harsh environment applications
- Built-in 4000 mAh replaceable battery and works for several years without replacement
- Store locally historical records and support retransmission to prevent data loss
- Support Milesight D2D protocol to enable ultra-low latency and direct control without gateways
- Equipped with NFC for easily configuration
- Compliant with standard LoRaWAN® gateways and network servers
- Quick and easy management with Milesight IoT Cloud and Milesight Development Platform
Milesight EM300-ZLD Product Description & Topology
EM300-ZLD is a compact zone leakage detection sensor for detecting large area presence of water (or other conducting liquids) and transmitting alarm using LoRaWAN® technology. In addition to LoRaWAN® technology with low power consumption, it has a built-in high-capacity battery available for several years without replacement. Combining with Milesight LoRaWAN® gateway, users can manage all sensor data remotely. EM300-ZLD also integrates temperature and humidity sensors, which has a great use for applications such as pipe leakage monitoring, basement flooding, pump failure, etc.
