Waiting Room Management & Patient Flow.IoT Blueprint.
The problem: Overcrowded waiting areas and stressed reception staff. The solution: An invisible digital guidance system with anonymous sensors.
- Occupancy of all areas in real-time
- 100% GDPR-compliant – no cameras, no faces
- Traffic light system at reception: Green/Yellow/Red
The Bottleneck at Reception.
In large practices, medical centers, or emergency rooms, overview is often lacking. Reception staff don't know:
The consequence: Patients are sent to overcrowded areas, rooms stand empty, and staff constantly have to get up and check ("sneaker interface").
Transparency Through Sensors.
We install a LoRaWAN sensor network that measures occupancy without violating privacy.
Waiting Areas
Ceiling sensors count heads – anonymized and GDPR-compliant.
Treatment Rooms
Presence detectors recognize whether a room is occupied – even for people with minimal movement.
Control Center
A tablet at reception shows the live situation in a traffic light system.

From Sensor to Control.
Raw data isn't enough. We program the logic behind it (merkaio dev):
if (waitingRoom.count < 10) {
status = "GREEN"
} else if (waitingRoom.count > 15) {
status = "RED"
redirect → "Bereich B"
}if (room.usageCount >= 10) {
notify("Reinigung")
→ "Raum 5 desinfizieren"
}// Dienstag 10-12 Uhr
if (avg_occupancy > 130%) {
recommendation:
"Schichtplan anpassen"
}Is This Allowed?
Yes. The system is "Privacy by Design".
