Embedded

Programming challenges in the embedded domain are very different from those you find when developing web or mobile applications. Programmers with required experience is a scarcity

Smart Gateway

Cloud

• responsive • reduce bandwidth • reduce latency • keep data secure • local logic

GatewayThe robustness and intelligence of your IoT applications depends on how you develop the software controlling the things

Air Ventilation MonitoringExample: Air Ventilation Monitoring

This gateway application communicates with a PLC via Modbus and a backend system. At first glance it looks rather simple but concurrency issues soon become a challenge.
