Quick Answer A 7-inch industrial HMI (Human Machine Interface) with multi-protocol support provides a ruggedized touchscreen display for monitoring and controlling industrial equipment. It connects simultaneously via Modbus RTU, Modbus TCP, CAN bus, and MQTT, with a unified tag address…
Quick Answer A LoRa-based environmental monitoring network uses long-range (up to 15 km in rural areas), low-power wireless communication to connect distributed sensor nodes measuring air quality, water level, soil moisture, and weather parameters across wide geographic areas. Built with…
Quick Answer A high-speed 16-bit data acquisition (DAQ) system for CNC machines captures vibration, force, temperature, and motor current data at sampling rates up to 500 kSPS (kilo-samples per second) with 16-bit resolution. Built around the STM32H743 and ADS8686 ADC,…
Quick Answer An STM32 Industrial Serial Server with 8 isolated RS-485 ports enables simultaneous connection of up to 8 serial devices — PLCs, variable frequency drives, power meters, sensors, and RTUs — to an Ethernet network. Each port operates independently…
Quick Answer A Modbus RTU to TCP/Cloud Protocol Gateway translates serial Modbus RTU messages from field devices into TCP/IP-based protocols (Modbus TCP, MQTT, HTTP REST) for cloud connectivity. This enables legacy industrial equipment to integrate with modern IoT platforms without…
