About Product
The WL-WSN Trainer is a portable Wireless Sensor Network testbed using ESP32 modules for real-time study of Wi-Fi communication, routing, and sensor-based applications. It supports up to multi-nodes with self-organizing multi-hop networks and requires no frequent reprogramming. A user-friendly GUI enables easy setup, monitoring, and control for practical WSN experiments.The trainer includes support for Wi-Fi based communication, sensor interfacing, and routing experiments, enabling realistic hands-on WSN learning and application testing.
Real-time wireless communication testbed for indoor & outdoor experiments.
GUI-based configuration of nodes, routing, bandwidth, throughput, and network parameters.
Supports multi-hop networking, packet analysis, bandwidth analysis & signal-strength studies.
Ideal for learning wireless communication, IEEE 802.11 fundamentals, and IoT sensor applications.
It includes on-board peripherals such as Relay, PWM LED, ADC (1 k pot), DAC output, and BME280 (Temp/Humidity/Pressure).
