    Overview

    The small raindrop sensing rain sensor adopts a special structure design to accurately control the size of raindrops, and combines the optical sensing principle to count raindrops one by one, so as to achieve high-precision measurement of rainfall. The output signal of SUCH sensor can be RS485/pulse output, supports 5V DC or 9~30V DC wide voltage power supply, and the power consumption is less than 0.24W. Its measurement range is 0~4mm/min, and the resolution is 0.03mm. It adopts a metal shell and has IP65 protection capability. It is widely used in smart meteorology, precision agriculture, hydrological monitoring and automated environmental systems.

    Feature

    • Compact size, lightweight, and easy to install.
    • Only 7.5cm in diameter and under 9cm in height, making it highly suitable for integration with other sensors.
    • High reliability, operates normally in high-temperature and high-humidity environments.
    • No moving parts, minimizing wear and tear and ensuring easy maintenance.
    • Innovative drop-sensing design for accurate rainfall measurement.

    FAQ
    ❯

    This sensor adopts the drop-sensing principle, controls the size of raindrops through a special internal structure, and uses optical sensing to accurately count raindrops to calculate rainfall.

    ❯

    Unlike traditional tipping bucket, pressure-sensing or ordinary optical sensors, it is smaller in size, more accurate, more reliable in structure, has no mechanical moving parts, is not easy to wear, and has a more sensitive response.

    ❯

    Drop-sensing rain sensors are widely used in smart agriculture, meteorological environmental protection, smart irrigation, automatic weather stations, ship navigation, automatic door and window control, geological disaster warning and other industries and scenarios.
