Study on precise mushroom cultivation based on feedback perception

In order to precise control the planting process and monitor mushroom growth in real time online, the design scheme of the environment monitoring system based on Internet of things was put forward on the main environmental parameters that affect the growth of mushroom. And according to the mushroom environment characteristics, the appropriate sensor and sensor placement were chose. By using RS-485 bus technology the information acquisition module, display module, communication interface and control interface monitoring terminal were built up. For the wiring is not conducive to the place in the mushroom room, its environmental information preclude the use of wireless sensor networks. On the server side is a web house environmental monitoring system was build based on the MySQL database - On the network communication interface the ENC28J60 Ethernet controller was used. In order to obtain the perceived data more accurately and effectively, loss-based retransmission detection based on the ACK scheme is adopted in the wireless sensor network. Experimental results show that this method can effectively improve the reliability of the data.
