The Wireless Sensor Network Trainer tends to demonstrate the theoretical and practical knowledge of Wireless Sensor Networks.
- The trainer contains one Main module (Base Station). It can be connected to a sensor module or actuator module and connected to
- PC using USB serial interface.
- The trainer contains 9 Node modules each of them can be connected to a sensor module or actuator module. These 9 Node modules communicate with Main module using Zigbee module / NodeMCU.
- The modules of the trainer are designed for low power consumption and operated by 9V battery.
- The trainer contains extension modules (Temperature sensor, Humidity Sensor, CDS Photo sensor, RTC, RFID, Ultrasonic and relay).
- The trainer provides programs for exercise and experimental manuals.
