The EM300-DI is a small LoRaWAN pulse counter that converts traditional water metres into wireless smart metres. Its IP67 waterproof design makes it suitable for use in a variety of harsh application environments.
It has a built-in high-capacity battery that will last for several years without needing to be replaced, in addition to LoRaWAN technology with low power consumption. Furthermore, the EM300-DI is compatible with both the Milesight LoRaWAN gateway and the Milesight IoT Cloud, allowing for remote monitoring and visualised smart data management to achieve the goal of water conservation. It is appropriate for both indoor and outdoor applications such as agricultural irrigation, industrial water use, property metre reading, and a variety of other scenarios.
