WIN-SN-TNH-VPD-M (OD)

The WIN-SN-TNH-VPD-M (OD) is an industrial-grade outdoor environmental sensor designed for precision agriculture, smart farming, and greenhouse automation. It measures temperature and humidity in real time to automatically calculate and output accurate Vapor Pressure Deficit (VPD) values directly via Modbus registers. Housed in a robust, low-maintenance outdoor enclosure, the device communicates over an RS485 interface using the standard Modbus RTU protocol. It features fully user-configurable communication settings, a built-in hardware factory reset, and seamless integration with PLCs, SCADA systems, and IoT gateways.
