Coverage you can prove
Per-room and per-shelf history shows temperature across the whole space, not one probe.
Solution
Cold Chain
Wireless sensors across cold rooms and chillers send readings over LoRa or BLE. IoTServa keeps the history and warns when a sensor goes quiet, not only when a room warms.
- LoRa
- BLE
- Modbus
The Problem on Site
A cold room is only protected if its sensors are alive. Batteries fade, doors block signal and a silent sensor looks the same as a stable one until a loss occurs.
Typical Equipment
- LoRa temperature and humidity sensors
- Door contact sensors
- BLE data loggers and tags
- Refrigeration controllers on Modbus
- Compressor power meters
What You Get to See
Silent sensors flagged
Missing readings, low battery and weak signal raise alerts of their own.
Alerts that escalate
Excursions notify the right person first and escalate when nobody responds.
Records for audits
Temperature history is exportable for food-safety and quality audits.
Protocols in This Setup
Each one is read natively and joins the same tag model.
LoRa
Receive LoRaWAN uplinks through your gateways, decode payloads into engineering units, and manage thousands of low-power sensors.
Read MoreBLE
Scan advertisements and read GATT services through BLE gateways, to track assets, rooms and short-range sensors.
Read MoreModbus
Poll Modbus RTU and Modbus TCP devices, decode registers with the right word order and scaling, and publish clean engineering values.
Read MoreWhere We Suggest the Pilot Starts
Start with one cold room and enough sensors to cover its warmest corners and its door. Confirm battery and signal alerts before adding rooms.
Questions for This Setup
How long do wireless sensors last on a battery?
It depends on the model and how often it reports. Report less often to extend life, and let IoTServa alert on battery level in good time.
Can it alert when a door stays open?
Yes, with a door contact sensor and a rule on how long it stays open.
