Wireless sensor networks have recently received a lot of interest in both the business world and our everyday lives because to the proliferation of sensor technology, MEMS, wireless communications, and the widespread use of wireless sensor. This study develops a wireless sensor network-based agricultural environment monitoring system, complete with hardware and software designs for sensor nodes, to achieve agricultural modernisation and agricultural environment protection. It has been shown via experimentation that the system can achieve remote real-time monitoring for unattended farm environment monitoring with a low power consumption, steady operating, and high accuracy.
