🔥 Client Pain: OEM machine builder needed modern touchscreen HMI to replace legacy 7-segment displays. Seamless communication with PLCs from multiple vendors required.
Our Solution: Custom 7-inch STM32F7 HMI with RTOS-driven LVGL UI engine. Built-in drivers for Modbus TCP/RTU, CANopen, and Siemens S7. Configurable via SD card.
✅ First deployment in packaging machine. Reduced PLC wiring complexity by 40%. Product changeover time: 25 min to 3 min.
🔥 Client Pain: Food processing plant needed real-time temperature monitoring across 12 production lines. Wired sensors impractical due to washdown requirements.
Our Solution: STM32L4-based LoRa sensor nodes with IP67-rated enclosures. 868 MHz long-range transmission to central STM32F4 gateway with local data logging.
✅ 12-month battery life achieved. 99.2% data reliability over 500m range. Eliminated 2km of sensor wiring.
🔥 Client Pain: Chemical plant required continuous monitoring of reactor temperature, pressure, and flow with SIL-2 safety rating. Existing DAQ system failing intermittently.
Our Solution: STM32F4-based redundant DAQ system with dual ADC channels, hardware watchdog, and isolated 4-20mA inputs. SIL-2 certified firmware.
✅ Zero safety incidents in 18 months. 99.97% uptime achieved. Passed third-party SIL-2 audit.
🔥 Client Pain: Solar farm operator needed centralized monitoring of 500+ panel-level power optimizers. Existing system used proprietary protocol, no cloud connectivity.
Our Solution: STM32H7 data concentrator with dual Ethernet. Protocol converter from proprietary to Modbus TCP + MQTT bridge to Azure IoT Hub.
✅ Real-time monitoring of all 500+ optimizers. 15% improvement in fault detection time. ROI achieved in 8 months.
