Cold Chain Relevance: Digital Matter’s cold chain monitoring solutions combine GPS tracking with Bluetooth temperature sensors for comprehensive visibility of refrigerated assets. Their devices monitor temperature, humidity, moisture, and door events throughout the supply chain, with real-time alerts for temperature excursions. Purpose-built for African conditions including load shedding resilience, their NB-IoT network testing across South Africa demonstrates reliable performance for mobile cold chain assets. WHO-preferred supplier status and deployment by organizations including UNICEF validates their suitability for vaccine and pharmaceutical cold chain applications.
