Greenhouse Automatic Controller Configuration
Top's greenhouse automatic controller has comprehensive functions and high data measurement accuracy. It can collect data on dozens of environmental elements and has 16 relay outputs, which can control equipment at 16 points. The core component uses a high-performance 32-bit microprocessor as the main control CPU, with a built-in large-capacity data storage that can continuously store 20,000 data entries without loss. It features a portable, shockproof structure, industrial control standard design, suitable for use in harsh environments, and a large-screen graphic LCD display with Chinese character and graphic display functions, displaying multiple environmental data streams on one screen for easy on-site observation. Relay indicator lights indicate the on/off status of each relay.
SD Card and USB Flash Drive Data Storage Function: Monitoring data can be continuously stored using portable storage devices (USB flash drive or SD card), with arbitrary storage time settings. Data can then be directly imported into the computer. Due to the large storage capacity of USB flash drives or SD cards, long-term permanent data storage is guaranteed, thus the system features unlimited storage capacity.
Multiple Communication Interfaces: The system features multiple communication interfaces, including RS232, RS485, USB, and Ethernet. This allows for network control of multi-unit greenhouse groups via Ethernet and direct access to the international wide area network for remote network control of the greenhouse.
