Researchers at the University of Pretoria believe IoT devices hold the key to improving road safety and security.
The University of Pretoria’s Civil Engineering department is experimenting with Internet of Things technology that could provide an early warning system for dangerous road conditions.
Steyn’s team has also used sensors embedded in the road to study the thermal characteristics of paving materials and investigate road cracking.The ability to embed IoT devices in the built environment without any effect on signal transmission “has a lot of exciting applications,” Civil Engineering PhD candidate André Broekman told MyBroadband.
For instance, humidity and temperature sensors are used in UP’s Javett Art Centre to monitor the condition of expensive artworks. IoT technology communicates in real-time without human intervention, allowing ways to automate repetitive and time-intensive tasks. Commercially available IoT devices like the Arduino MKR WAN 1310 have a built-in LoRaWAN radio module that lets users build their own intelligence networks, said Broekman.
Automation and centralisation via IoT devices can eliminate human error from data collection, allowing users to focus on analysing data sets and extracting meaning from them.The cost of a LoRaWAN system with up to 15 sensors is approximately R15,000.
