Greenhouses provide a safe and healthy growing environment for crops, fruits, flowers, and other plants, protecting them from yield losses caused by adverse weather conditions. As science and technology continue to advance alongside rising quality standards in production, the demands on greenhouse systems have grown increasingly sophisticated. Efficiently leveraging IoT technology to control greenhouse irrigation has become a key focus for farmers.

PLC-controlled greenhouse irrigation systems enable automated irrigation under various environmental conditions, achieving precision irrigation and water conservation while also improving agricultural management and production efficiency. To this end, WideIOT offers a PLC remote monitoring solution that enables PLC data acquisition and cloud-based monitoring, with alarm notifications for abnormal data—helping enhance agricultural management efficiency and flexibility while advancing smart agriculture.

By deploying WideIOT industrial smart gateways, greenhouse PLCs can be adapted for protocol matching and data collection. Data is uploaded to cloud platforms and local host computers via 5G/4G/Wi-Fi/Ethernet. The system collects environmental data within the greenhouse, including real-time monitoring of soil temperature and humidity, air temperature and humidity, light intensity, and more. It also captures voltage and current signals to monitor equipment operating status. With this setup, managers can view data changes and perform management and control at any time from their phones, computers, or monitoring dashboards.

When abnormal environmental data or equipment faults are detected, the system automatically notifies management personnel via WeChat, SMS, or email, providing information such as the abnormal data, affected equipment, and timestamp. This enables timely corrective actions to maintain optimal environmental conditions, safeguarding agricultural productivity and product quality.
In addition, PLC engineers can remotely program, debug, and upload/download programs to PLCs at remote locations—eliminating travel costs and improving maintenance efficiency. By applying digital maintenance tools, agricultural operations become more stable and reliable.
