Simple Microcontroller-based Snowfall Sensor
- The power supply voltage is compatible with both 100V and 200V. To directly detect snowfall, it is less affected by wind, and by combining the snow temperature sensor signal, there is no malfunction due to low-temperature rain. - The sensor part uses weather-resistant plastic and stainless steel, which are excellent in rust prevention and weather resistance. - Even after the snow stops falling, it maintains output for a certain period (remaining snow processing time). - A built-in timer for manual operation stops the output after the set time. - The "Test" switch allows for operation confirmation of the main control unit. 【Intermittent Mode Operation】Only for FS-57 and FS-58 - Automatically switches between intermittent and continuous operation according to the snowfall amount. - Compared to the standard model (FS-55), it can achieve approximately 20% water and energy savings. *For detailed information, please download from the link below or feel free to contact us.

Company information
Niigata Electric Co., Ltd. was founded in 1973 in Nagaoka City, Niigata Prefecture, a snowy region. Since then, we have aimed to effectively utilize water resources and promote energy-saving snow melting systems, developing various automatic control devices and sensors related to snow, including the snowfall sensor "SnowCon." In the field of snow measurement, we have introduced products such as snow depth gauges, snow weight gauges, blizzard meters (SPC), and snow information systems, contributing to the development of snow and ice disaster prevention, snow information, and snow and ice research fields. Some of our developed products are unique to Niigata Electric and are not produced anywhere else in the world. Based on the technology, know-how, and achievements we have cultivated so far, we will continue to actively engage in the development of new products, applied technology, and collaborative research to contribute to a better society and a more livable snowy region. Please look forward to the future of Niigata Electric.
