【Abstract】With the development of vegetable and fruit planting industry, some new diseases and pests have also developed rapidly, which seriously affects the yield and quality of vegetables and fruits; the rapid development of chemical industry, greatly meet the needs of farmers to control diseases and insects, promote the development of agricultural production.However, the indiscriminate use and abuse of pesticides lead to the serious excessive pesticide residues in agricultural products, which greatly affects human health and causes environmental pollution and damage. At the same time, the pests produce anti-drug resistance characteristics.
The system uses AT89S52 as the main control chip of the system to realize the charging control of the battery by solar panels.Meanwhile, the working state of the insecticide lamp system is controlled through the temperature and humidity sensor. Realize the function of the system stopping working with low ambient temperature and rainy days, the temperature recovery and the system recovery after the rain stops. And the use of photosensitive mistor to control the insecticide lamp light, to achieve the battery charging during the day, night battery discharge to make the lamp light insecticide.
