JXBS-3001-YL-RS-JC ABS Rain Sensor - RS485 Digital Output

The sensor uses an RS485 serial interface, typically implementing the Modbus RTU protocol. This allows for robust, multi-drop communication over long distances (up to 1200 meters), making it suitable for integration with industrial PLCs, data loggers, and SCADA systems. You will need an RS485-to-USB or RS485-to-UART converter to connect it to a computer or microcontroller.

The sensor supports a wide DC input range of 5V, 12V, or 24V. This flexibility allows it to be powered directly from common power supplies, battery packs, or solar-charged systems used in remote monitoring stations. Ensure your chosen supply voltage is stable and can deliver the required current (less than 20mA).

Install the sensor on a stable, level surface in an open area, clear of obstructions like trees or buildings that could affect rainfall collection. Calibration is typically factory-set based on the tipping bucket volume per pulse. For precise measurement, verify the installation is perfectly horizontal. The RS485 output provides digital data (e.g., tip counts) which your monitoring software converts into rainfall depth (e.g., mm) using the sensor's resolution factor.

Yes, the durable ABS plastic housing is designed to withstand prolonged exposure to sunlight, rain, and varying temperatures. Its tipping bucket mechanism is constructed from weather-resistant materials. For optimal longevity, periodic maintenance is recommended to clear the funnel and bucket of debris like leaves or insects that could affect measurement accuracy.
