First, avoid planting cypress, pine trees. The major diseases of pear trees pear rust and brown spot disease damage new shoots, petioles, leaves, stalks, and young fruits of pear trees, resulting in fruit rot and even fruit drop. Cypress is a wintering place for Pear rust. In addition, cypress and vineyards cannot coexist. Otherwise it is easy to cause the grape fruit to mature late. The spores of pine trees floating in the wind orchards in spring and summer will seriously damage fruit trees, especially pear trees. Pine spores can cause macules in leaves and fruits of pears and severely reduce the fruit setting rate. Second, avoid planting hedgehog, artichoke. One is that the hedgehog is very easy to attract elephants, stinky bugs, peaches, plums, pears, apples. Second, the tannic acid substances secreted by hedgehogs have inhibitory effects on many kinds of fruit trees, especially pears and apples, which can lead to a significant reduction in fruit trees production. Third, the deciduous anthrax bacterium on the hedgehog infected pears, apples, and other fruit trees, causing a large number of fallen leaves. Third, avoid planting Paulownia. Many fruit trees are susceptible to purple feather disease, and the leaves yellow, dry, and even die. The paulownia is the wintering ground of the purple feather pathogen. Fourth, avoid banyan tree. Citrus trees and yew trees near the vineyard. Eucalyptus is a citrus nemesis and a brown horny tree. If eucalyptus is planted, it will induce the calf to feed heavily and multiply, and it will seriously harm citrus. The secretion of eucalyptus roots is very harmful to the grapes, causing the grapes to lose production or even die. Fifth, bogey walnuts. Walnut (walnut) leaves after the walnut pods after rain, drip into the soil and damage the apple root, inhibiting the growth of apples, so the apple orchards should not be planted around the walnut.
With long range distance sensor with digital output, you can measure and monitor distances intergrated to your arduino, raspberry pi etc. The Laser Distance Sensor low cost is a competitive measure sensor, can measure from 3cm to 40m, 100m, max to 150m with +-1mm~+-3mm accuracy.
