JW-XF100(YN17) Piezoelectric Rain Gauge is a compact rainfall monitoring sensor designed for 24-hour continuous outdoor rainfall measurement. It uses a maintenance-free piezoelectric sensing principle with no moving parts, making it suitable for meteorological monitoring, hydrology, water conservancy, smart agriculture, road safety, coastal rainfall monitoring, and energy site monitoring.
2. Product Overview
JW-XF100(YN17) Piezoelectric Rain Gauge measures rainfall by detecting the impact force of raindrops on its curved sensing surface. Compared with traditional tipping bucket rain gauges, it has no mechanical moving parts, reducing maintenance requirements and making it suitable for mobile, remote, or hard-to-maintain monitoring sites.
Its arc-shaped top cover helps prevent water retention, supporting stable outdoor operation. With RS485 Modbus RTU output, low power consumption, IP65 protection, and compact sleeve mounting, this rain gauge can be easily integrated with weather stations, data loggers, RTUs, IoT gateways, and environmental monitoring platforms.
This sensor is ideal for projects that need compact rainfall monitoring, continuous rainfall accumulation, rainfall duration, rainfall intensity, and maximum rainfall intensity data.
