EM300-CL is a non-contact liquid level sensor based on LoRaWAN®, which relies on capacitive sensing principle. It is mainly used to monitor hand wash in restrooms and sending out alarms when there is insufficient hand wash left. An alarm will be triggered when the hand wash level approaches the electrode detection sheet, signaling hand wash insufficiency. It can be seamlessly integrated with containers of different shapes and sizes to alert and assure hand wash is replenished on time, promoting the good operation of smart hygiene and cleaning management system. In addition, with LoRaWAN® technology that supports low power consumption, it allows the built-in high-capacity battery to last for several years without replacement. Moreover, EM300-CL is compatible with both Milesight’s gateway and Milesight IoT Cloud to achieve remote monitoring and smart data management, allowing water conservation.
