Milesight EM300-ZLD

EM300-ZLD is a compact zone leakage detection sensor for detecting large area presence of water (or other liquids) and transmitting alarm using LoRaWAN® technology. 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.
