LORAWAN Wetness Sensor for Smart Restrooms

LoRaWAN Wetness Sensor

The LoRaWAN Wetness Sensor is an intelligent, non-contact floor wetness monitoring solution designed to detect water leakage, moisture, and liquid spills in real time. It is particularly suitable for restrooms, kitchens, utility areas, industrial plants, and other spaces where water accumulation can create safety, hygiene, or maintenance concerns.

The sensor uses thermal sensing technology with edge-based AI/ML processing to identify temperature variations associated with wet or dry floor conditions. Once wetness is detected, the sensor communicates the event over the LoRaWAN network, enabling real-time alerts and remote monitoring through the connected dashboard. The edge processing also allows floor temperature data to be analysed locally without transmitting images, supporting privacy-conscious deployments.

Key Features

• LoRaWAN Connectivity: Long-range, low-power wireless communication through a LoRaWAN gateway.
• Real-Time Wetness Detection: Detects moisture and water accumulation on the floor.
• Thermal Sensing Technology: Identifies temperature differences on the floor to detect wetness.
• Edge AI/ML: Local edge processing enhances detection capability using an onboard trained model.
• Adjustable Sensitivity: Can detect conditions ranging from light moisture to standing water.
• Wide Detection Coverage: Detection area of approximately 3 m × 2.5 m at a 2.4 m ceiling height.
• Privacy-Friendly: Processes thermal data at the edge without relying on conventional visual imaging.
• Remote Alerts: Supports SMS, email, and dashboard notifications through the LoRaWAN gateway. – Ceiling-Mounted: Enables monitoring of floor areas without installing sensors directly on the floor.
• IP54 Enclosure: Suitable for indoor environments with exposure to moisture and humidity.

Technical Specifications

The above specifications are based on the supplied Tynasense product brochure.

Applications

• Smart Restrooms: Detect water accumulation and leakage around washbasins and toilets.
• Industrial Facilities: Monitor areas where liquid spills may create safety or operational risks.
• Commercial Buildings: Monitor wetness in common areas and utility spaces.
• Kitchens and Cafeterias: Detect water or liquid spills and enable faster cleaning response.
• Facility Management: Generate incident data to optimize cleaning and maintenance schedules.
• Water Leakage Monitoring: Provide early notification of water accumulation before it results in larger damage.

Benefits

• Reduce Slip-and-Fall Risks by identifying wet floors quickly.
• Faster Maintenance Response through real-time remote alerts.
• Reduce Maintenance Costs by detecting spills and wetness before they cause further damage.
• Improve Hygiene and User Experience in shared and public spaces.
• Data-Driven Facility Management through incident tracking and analysis.
• Privacy-Conscious Monitoring through edge-based thermal data processing rather than conventional visual surveillance.
