Research and implementation of location technology of wireless local area network in field greenhouse

In the field of information collection process, we not only pay attention to the environmental temperature, humidity, light, etc, but also hope to accurately locate acquisition nodes. Especially in the study of soil pH and soil nutrients, the soil pH is not uniformly distributed in different regions. In this paper, we constructed a wireless positioning sensor network based on the Zigbee technology, adopting multi-user RSSI algorithm. We designed the hardware and software of the wireless positioning system and finally performed positioning system testing in the field greenhouse.
