COMPTUS A70H-RF Radar Rainfall Sensor Instruction Manual
The A70H-RF Radar Rainfall Sensor is a sensor that uses radar wave technology to detect rainfall. It can distinguish the types and intensity of rain, snow and hail. Compared to that of a traditional mechanical rain gauge, the detection is more senstive and fast, and there is no need to worry about the influence of the cover of leaves and other objects on the surface of the dectoector for rainfall detection, and no need for heating device to prevent icing. There are no moving parts inside of the product, which is maintenance free, small in size and low in energy consumption.
