The Milesight EM300-SLD 868 is a LoRaWAN-based leak detection sensor designed for precise monitoring of fixed leakage points.
The stainless steel probe detects conductive liquids when the liquid level reaches 5 mm and immediately triggers an alarm. This probe-based design is ideal for monitoring specific high-risk locations rather than covering large surface areas.
The 1.5 m cable allows flexible probe positioning while the transceiver can be mounted separately.
In addition to leak detection, the device integrates temperature and humidity sensors for combined environmental monitoring.
The IP67-rated housing ensures reliable operation in industrial and outdoor environments. Internal storage of 2,800 records plus retransmission support guarantees complete event logging even during temporary network interruptions.
Powered by a 4000 mAh battery, the device can operate for over 10 years depending on reporting configuration (EU868, SF7).
Typical applications:
Server rooms
Pump stations
Machinery monitoring
Technical rooms
Under-sink installations
Industrial facilities
Facility management systems
