Hail detection sensor

A hail detection sensor, comprising a base and at least two detection components;

• each of the detection components is provided with a support, a displacement detection device, an elastic body, and a force-bearing part of a given mass, the surface of the force-bearing part is provided with a Zone I for the impact of the measured hail, and the force-bearing part is a conductor, and the force-bearing part is fixed on the support through an elastic body, the displacement detection device is used to obtain a first signal reflecting the mechanical vibration generated by the hail impacting the force-bearing part, wherein, there is a gap between each of the Zone 1, the area of each of said Zone I is configured to be smaller than a standard hail density measurement area, and the sum of the areas of each of the Zone 1 on the hail detection sensor is configured to be larger than the standard hail density measurement areal, the said standard hail density measurement area is 30 cm×30 cm or greater;
• and
• at least one of the supports is fixed to the base, and the base has electrical conductivity, and each force-bearing part is electrically connected to the base and electrically connected to earth through the base.
