Temperature monitoring systems for cold rooms and storage

Calo connects temperature sensors to OnSight so your team can review readings, receive alerts and check temperature history. We work through sensor placement and integration with your existing systems, and can also connect equipment detection records.

OnSight is powered by Calo and Philo Software. Calo brings software development, hardware integration and an understanding of how your team works.

What does your team need to know?

Start with the readings or equipment records that would make a difference to daily work.

Cold-room temperature monitoring

Bring sensor readings, threshold alerts and temperature history into a workflow your team can use. Review conditions across cold rooms, freezers and refrigerated storage.

Agree sensor placement, reading frequency and who receives alerts for your site. Monitoring supports your team's response and record keeping; it does not control refrigeration or establish compliance on its own.

Equipment tracking

Use tags and gateways to record equipment detections across warehouses, worksites and customer locations. Check where an item was last detected and when that record was made.

A new gateway detection updates the location record. Outside coverage, the last detection stays on file. Range, coverage and update frequency need to be assessed for your equipment and sites.

Make the records work with your business.

The useful part is what your team can do with the information. Calo works through the process, the devices and the software connections with you.

Explore Calo's integration services

Understand the operation

Identify what needs to be monitored, where equipment moves, and which gaps in today's records cause extra work.

Assess the connections

Review existing sensors, tags, gateways and software. Check available data and compatibility before choosing an integration.

Build around the workflow

Connect agreed readings and events to the systems your team uses. Decide what they need to review and who acts on it.

Test the uncertain parts

Check device coverage, data quality and the operator's view with a first site or process before extending the solution.

How the information connects

  1. Sensors and gateways

    Supply readings and detections

  2. OnSight Core

    Receives events and records history

  3. OnSight Command

    Presents the recorded information

  4. Your team

    Reviews records and responds

Monitoring and tracking in practice.

Different operations need different setups. These projects show how OnSight has been put to work.

Refrigerated containers and the temperature-monitoring hardware used at Franklin Foods

Franklin Foods

Remote readings across refrigerated containers

Probes inside four refrigerated containers and transmitters outside worked around the metal walls. OnSight brought temperature readings, alerts and reporting into the monitoring workflow.

Super City Chemdry

A starting point for finding missing equipment

Around 800 items move between the warehouse and restoration jobs. BLE tags, a warehouse gateway and technicians' phones give the team recorded detections to guide equipment checks.

Steel coils and the tracking setup from the NZ Steel pilot

NZ Steel

Detecting steel coils between covered zones

In this pilot, BLE beacons identified steel coils and gateways recorded detections within covered zones, without workers scanning each coil individually.
