Dairy Temperature Alerts in Dagestan

A dairy distributor operated 12 refrigerated trucks with ageing refrigeration units. Equipment failures created a risk of rising cargo temperatures during deliveries.

The supplier needed to know when a monitored area became too warm and when its temperature returned to the configured range. Staff could then follow up during the journey instead of discovering a problem only at delivery.

SMART S-2421 trackers were installed in all 12 trucks. Four wired temperature sensors were connected through 1-Wire in each refrigerated compartment. Temperature notifications were configured using the device’s standard settings, without Complex Events.

The supplier gained notifications covering both the start and end of a temperature deviation across its 12 trucks.

Staff could direct attention to an affected vehicle, request a check and see whether the monitored temperature subsequently recovered. This reduced the need to repeatedly request temperature updates from drivers or continuously watch readings.

S-2421 gave the supplier a practical way to manage temperature exceptions across a larger fleet. Staff knew which delivery needed attention and received a follow-up when the affected reading recovered, helping them distinguish an ongoing problem from one that had returned to the configured range.

For a distributor using ageing refrigeration equipment, that meant an opportunity to intervene during transport. Earlier attention could help limit spoilage, rejected deliveries and replacement costs. The required warning-and-recovery process was achieved through standard device settings, without a custom control program.
