Product Description


Product description

RS-100 optical rain sensor uses optical induction principle to measure rainfall. Multiple optical probes are installed, and reliable remote sensing algorithm is adopted to ensure reliable detection of rainfall. Different from traditional mechanical sensors, optical rainfall is smaller, more sensitive, reliable, intelligent and easy to maintain. This product supports boot calibration and installation error reminders, supports switching volume and UART output.




lSupport switching value and UART output

lAutomatic calibration,(not easily affected by the external environment)

lSimple installation,suitable for all kinds of complex installation environment

lMaintenance free design,(The deciduous leaves are not easy to cover)

lLong service life,(Over 5 years)

lHigh-precision,(Automatic measurement)

lLow-power design

lMulti interface mode

lSupport boot calibration and installation error reminding
