1. Product Introduction

To monitor rainfall in real-time accurately and achieve automatic rainfall measurement and warning functions, our company has independently developed and produced an integrated rain gauge with a single-chip microcomputer as the control core. This rain gauge combines advanced system software and hardware to achieve real-time, accurate, and effective automatic measurement and reporting of rainfall in a specific area.

The integrated rain gauge is suitable for mountain flood disasters, rainstorm monitoring, and mobile emergency monitoring. As an integrated device, it can automatically collect and store rainfall data, supports data transmission methods such as GPRS/satellite communication, and is made entirely of stainless steel for long service life.
