Latest low-cost rain gauge using infrared light!!

It uses the same method as the rain sensors found in automobiles in recent years. There are no mechanical moving parts, and it can be finely adjusted from the beginning to the end of rainfall according to each rain sensitivity setting. Additionally, as a rain gauge, it has control outputs for devices related to rain and agricultural facilities, allowing for a wide range of applications such as opening and closing awnings for open stores and skylights in greenhouses. Note: We have started handling new products, including a high-precision rain gauge version and a rain sensor specialized version!
