【High Quality】The rain sensor module is made of high-quality FR-04 double-sided material, with a stable structure, good electrical performance and mechanical strength. The 5.0*4.0CM large area design enhances the sensing sensitivity, and the surface nickel plating effectively prevents oxidation and corrosion, improves conductivity and service life, and is suitable for various complex environments 【Application】The rain gauge relay control module can be directly connected to a high-power relay to easily realize intelligent control of load equipment such as water pumps, drainage systems, and automatic awnings. Whether it is a home balcony, a greenhouse, or an industrial plant, it can realize automatic rain response management and improve ease of use 【Function】The raindrop sensor is equipped with an independent potentiometer, which can adjust the sensing sensitivity according to actual needs and adapt to the trigger threshold under different rainfall intensities. Users can freely set the relay to start in light rain or heavy rain to meet personalized control needs and improve the intelligence level of the system 【Durable】The sensor module is made of high-quality materials with high wear resistance and anti-aging properties, and can operate stably in outdoor or humid environments for a long time. The structure has good sealing, high dust and water resistance, and can effectively resist wind, sun and rain erosion, ensuring long-term use without damage and reducing maintenance frequency 【Good Performace】The rain sensor has a built-in professional chipset with fast response capability and stable signal output performance, which can accurately identify rainfall changes under changing weather conditions. The precise sensing mechanism provides reliable data support for the automation system, ensuring the efficient and safe operation of the entire control system, Weight: 0.0551155655 Pounds, Manufacturer: Kuuleyn
