All sensor node power sources are independently controlled, system power consumption can be effectively reduced, and the requirement for long-time work in the field is met.

Description

technical field [0001] The invention relates to an agricultural environment information collection and control device with a sensor interface circuit, which belongs to the field of agricultural technology. Background technique [0002] Agricultural environment refers to the totality of various natural and artificially modified natural factors for the survival and development of agricultural organisms. Agricultural environmental monitoring is to monitor the environmental parameters of agricultural sites by physical and chemical means. For a long time, agricultural production has adopted extensive management, making judgments on the crop environment based on the experience of producers, and then taking corresponding measures. With the development trend of precision agriculture, more and more attention is paid to the collection of environmental information, and sensors such as soil temperature, soil humidity, and light have been used, but the manual discrete collection method i...

With the development trend of precision agriculture, more and more attention is paid to the collection of environmental information, and sensors such as soil temperature, soil humidity, and light have been used, but the manual discrete collection method is still the main method, and the workload is heavy, and real-time and long-term monitoring is not possible. Making judgments about the agricultural environment
