Abstract
The quality and energy consumption of wireless communication are the key factors that restrict the wide application of wireless sensor networks in greenhouse system. A reliable wireless monitoring and control system with low power for greenhouse was designed. The acknowledgement (ACK) mechanism was adopted to improve the wireless communication quality. The low power listening (LPL) technology was used to reduce the energy consumption of wireless nodes. In addition, the software watchdog was adopted to improve the anti-jamming capability of nodes. Test results show that there is no data packet loss during wireless transmission process. The current of nodes by using the LPL technology is much lower than that under the three working states of transmit, receive, and idle. The wireless monitoring and control system can meet the actual requirements of greenhouse microclimate.KeywordsGreenhouseWireless sensor networkCommunication qualityLow power consumption
