Customs and port warehouse monitoring
Monitors temperature, humidity, water ingress and access in customs and port warehouses, so cargo that sits for weeks is released intact.
Why this monitoring is needed
Cargo in a customs warehouse has no owner present. It sits for weeks in a shed with no controlled ventilation and nobody accountable for its storage conditions. When it clears and turns out damaged, the dispute between the consignee, the warehouse operator and the insurer begins — and none of them has any evidence.
In ports, humidity is the main issue. Damp marine air combined with the daily temperature swing condenses on cool cargo — the phenomenon known as container sweat, which ruins cartons, labels and metal alike.
What gets measured
Per-shed temperature and humidity
Several points per shed — conditions by the loading door and deep inside are entirely different.
Dew point
Computed from temperature and humidity; cargo surface temperature approaching dew point is the moment of risk.
Water ingress and rain leaks
Sensing cable along external walls and under ageing roofs catches ingress before it reaches the cargo.
Access and door openings
Every shed door opening is timestamped — for bonded cargo that is both a security and a process record.
Power to yard reefers
Reefer containers in the yard depend on plugged power; losing a row's supply destroys that row's cargo.

- 1
Cargo surface temperature approaching dew point: condensation alarm with ventilation or dehumidification started.
- 2
Humidity sustained above threshold in one shed: alarm naming the shed and the duration.
- 3
Any water on the sensing cable: immediate SMS to the duty warehouse officer.
- 4
Shed door opened outside working hours: timestamped security alarm.
- 5
Power lost on a reefer plug row: top-priority alarm — the whole row's cargo is at risk.
What the operator gets
Storage conditions for each consignment are documented, settling insurer and consignee disputes on data.
Condensation and moisture damage are contained by a pre-emptive alarm.
Loss of reefer power is announced within the minute.
Frequently asked questions
Our sheds are very large — how many points are needed?
The practical rule is to cover zones that behave differently: by the loading door, deep inside, under the roof and at floor level. A CANopen card carries up to 64 sensors on one cable, so adding points costs no new home runs — start with a few and extend.
What about the open yard and the containers?
For the yard, LoRa wireless sensors reach up to 1 km line of sight with no cabling. For reefer plugs, a 3-channel AC voltage detector covers each row and reports a power loss immediately.
