Automate homes and factories using PLC/Arduino/ESP32 control, SCADA/HMI interfaces, Modbus/CAN, and VFD motor drives with relays, solenoids, and servos. Build smart lighting/HVAC, access control, conveyor & pick-and-place, tank level & pump control, and energy monitoring with load-shedding, predictive-maintenance (vibration/temperature), and safety interlocks—plus MQTT/Node-RED/ThingSpeak IoT dashboards and cloud alerts. Ideal for diploma/BE final-year—kits include parts, code, circuit, report, and support.
