Wireless ANDON Tower with NRF24L01

The ANDON tower uses the low-cost NRF24L01 transceiver to send the experimental data from the sensor node to the coordinator node, with a computer connected to the coordinator node to store the data in a CSV file. The transceiver uses the SPI protocol for communication with the ANDON tower microcontroller. Its maximum range is 30 meters, however the maximum distance in the experimental scenario is 16 m. The transceiver works in the 2.4GHz free band and allows setting the transmission power in -18dBm, -12dBm, -6dBm and 0dBm. The transmission rate setting options are 250kbps, 1Mbps and 2Mbps. The communication tests were realized sending a payload of 2, 4, 8, 16 and 32 bytes.

ANDON 塔采用低成本 NRF24L01 收发器，将来自传感节点实验数据的传输至协调节点，其中连接至协调节点的计算机用于将数据存储于 CSV 文件中。该收发器与 ANDON 塔微控制器间的通信采用 SPI 协议。其最大通信距离可达 30 米，但在实验场景中的最大距离为 16 米。收发器工作于 2.4GHz 的开放频段，并允许在 -18dBm、-12dBm、-6dBm 和 0dBm 的传输功率中进行设置。传输速率的设定选项包括 250kbps、1Mbps 和 2Mbps。通信测试通过发送 2、4、8、16 和 32 字节的有效负载来实现。
