STE-R1 Lorry Temperature Sensor for Cold products Supply Chain

GoTrack STE-R1 Temperature Monitoring Device — Product Overview

The Challenge

Businesses transporting temperature-sensitive cargo — fresh produce, meat, seafood, dairy, pharmaceuticals, vaccines, and frozen goods — face significant operational risk when they lack real-time visibility over in-transit temperatures. On long-haul routes, fleet managers have little ability to proactively monitor cargo conditions, and by the time a threshold breach is detected, the damage is often already done.

The core questions operators face:

• How can both drivers and managers monitor refrigerated cargo temperatures conveniently and in real time?
• How can spoilage be minimised during transit?
• How can temperature excursions be detected and actioned immediately?

The Solution: GoTrack STE-R1

Developed with a deep understanding of cold chain logistics challenges, the STE-R1 is GoTrack's purpose-built temperature sensing device, featuring a long-reach PT100 sensor probe paired with an onboard LED display unit. It integrates seamlessly with GoTrack's 4G-compliant GPS trackers (S400/S400E) to deliver end-to-end cold chain visibility.

Operating Modes

Mode 1 — Standalone Operation The STE-R1 functions independently as an in-cabin temperature monitor. Temperature readings display in real time on the LED screen, giving drivers continuous awareness of cargo conditions. Note: remote monitoring by fleet managers is not available in this configuration.

Mode 2 — Integrated with GoTrack 4G GPS (Recommended) When paired with the S400 or S400E, all temperature, location, speed, and timestamp data is transmitted to the GoTrack platform and accessible via mobile app, web browser, or desktop. Managers receive instant push notifications upon any threshold breach, with full contextual data — temperature reading, vehicle location, speed, and time of alert. Both drivers and fleet managers maintain 24/7 visibility over all refrigerated units simultaneously.

Key Features

• Real-time temperature monitoring across all refrigerated vehicles simultaneously, viewable on any smart device
• Instant alerts via the GoTrack App when cargo temperature exceeds pre-set thresholds
• Live data transmission — temperature, GPS location, speed, and route history logged to the server and displayed on App/Website
• In-cab LED display for driver-side awareness without reliance on connectivity
• Comprehensive reporting — view and export data in multiple formats including charts, detailed logs, and advanced comparative reports
• Long-reach, slim-profile PT100 probe — easily routed through tight spaces and across multiple cargo compartments
• High accuracy, stable performance across diverse environmental conditions
• Simple installation via straightforward cable connection
