The Milesight EM300-CL is a LoRaWAN® capacitive liquid level sensor designed for smart restroom hygiene operations—especially monitoring soap or hand-wash refills without direct contact. Using an external electrode pad, it detects level status through the container wall, helping reduce contamination risk while supporting flexible deployment across different bottle shapes.
Key features:
- Non-contact capacitive sensing with dual-electrode design for strong anti-interference performance and reliable level status reporting.
- Built for demanding environments: an IP67-rated transceiver housing and battery-powered operation (4000mAh ER18505 Li-SOCL2, extendable) for long-term, low-maintenance installations.
- Simple commissioning and management: NFC configuration via mobile app, plus remote monitoring and alerts through the Milesight IoT Cloud when paired with a compatible LoRaWAN® network.
Use case: In commercial buildings such as offices, malls, hotels, and clubs, EM300-CL helps facility teams stay ahead of replenishment needs by receiving timely “low level” alerts across multiple restrooms. linko can support end-to-end planning in Hong Kong—from sensor placement and gateway selection to system integration, installation, and ongoing optimization.
