Wireless Sensor Networks
Design, deploy and debug low-power sensor networks from node to gateway.
A six-week intermediate course on wireless sensor networks: radio fundamentals, node architecture, short-range and LPWAN protocols, network topologies, routing, gateway design, power budgeting, security and real-world deployment with Arduino, ESP32 and LoRa.
Intermediate
6 weeks 18 lessons Arduino Uno, ESP32, nRF24/ BLE, LoRa/LoRaWAN modulesCourse content
Six weekly modules. Each lesson unlocks once you complete the one before it.
