The maintenance-free and weather-proofed (IP67) rain / snow / condensation / moisture sensor FR-1 is a versatile sensor to detect rain, snow, condensation, moisture, strong dew.
A two-stage heating avoids in stage 1 condensation on the sensor / measuring surface. Stage 2 ensures that detected condensation / moisture will dry rapidly.
In combination with the evaluation instrument AR-1 a control and evaluation system exists to control illumination, light, jalousies, marquees, blinds, shutters, air conditioning, heaters, ventilation, flaps, roof hatches and build-ups
