The CoolTeck BLE Wireless Door Sensor provides reliable, real-time door status monitoring for cold rooms, refrigerators, and temperature-controlled storage environments. Designed to help protect sensitive goods, it detects door opening and closing events, supporting improved security, operational visibility, and cold-chain integrity. Its wireless BLE connectivity enables convenient integration with compatible CoolTeck monitoring systems, helping teams track access events and identify doors left open for too long.
| Best for | Cold rooms, refrigerators, and controlled storage areas |
| Features | Light sticky Door Sensor · Accessible through Kbeacon mobile app and Cooltech Gateway |
| Primary function | Door open/close status monitoring |
| Broadcast | 50m programmable BLE beacon + temperature |
| Connectivity | Bluetooth Low Energy (BLE) |
| Monitoring | Door opening and closing events |
| Key benefits | Access visibility, door activity tracking, and support for identifying prolonged door openings |
| System integration | Compatible CoolTeck BLE monitoring systems |
The CoolTeck device continuously measures temperature (and humidity, on the BLE unit) at the storage point or on the goods in transit.
Readings are sent over 4G/GSM, or broadcast via BLE to the nearest IOTPIA Gateway, with up to 200 readings buffered locally.
Data flows into CoolTeck Cloud, or any MQTT / HTTP server your business already runs — no vendor lock-in.
Out-of-range readings trigger the integrated alarm buzzer and cloud alerts, while the full history stays available for traceability and audits.
Keep sensitive stock inside the 2–7°C window regulators require.
Monitor refrigerated vehicles in real time, even outside network coverage.
Standalone monitoring for small rooms without existing infrastructure.
Traceable temperature records from warehouse to last-mile delivery.
CoolTeck deployments follow a WHO-informed thermal mapping methodology, with sensor counts, wall coordinates and gateway placement calculated from actual room dimensions — not rules of thumb.
Choose the rigor your room needs — from a full WHO Testing mapping study, to a Pharmaceutical Level deployment, down to Minimal Coverage for lower-risk spaces.
Every room is designed both ways — wired gateways (4 sensors each) with full cable schedules, and wireless gateways (4/6/8/10 capacity) with calculated shared redundancy.
Full methodology, room-by-room figures and three coverage-level options.
