Product Overview
This instrument is a drip-sensing rainfall sensor that adopts an innovative drip-sensing design concept. It uses a specially designed internal structure to precisely control raindrop size and employs optical sensing technology to count raindrops, thereby measuring rainfall accurately.
Unlike traditional tipping bucket, pressure-sensitive, or optical rainfall sensors, this sensor combines the advantages of these three principles while overcoming their shortcomings. It achieves a compact size and high measurement accuracy.
The sensor can be widely applied in various fields, including smart agriculture, meteorology and environmental protection, smart irrigation, maritime navigation, automatic weather stations, automatic doors and windows, and geological disaster monitoring.
