Fruits and vegetables sustain mechanical damage from impacts and vibrations during transportation. To measure the degree of impacts and vibrations, an impact counting device was developed, which can be packed with fruits in a corrugated cardboard box and transported. Between the transportation, the apparatus counts the number of impacts above the threshold acceleration in each of triaxial directions. The impact counter consists of a sphere for detecting the acceleration and a box with an electronic circuit. The sphere is made of acrylic resin and contains a triaxial piezoelectric accelerometer.
