Capacitive Level Sensor: EM300-CL

DATASHEET

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.
