The solar LED pest control light is environmentally friendly, energy-saving, easy to use and independe nt of the electricity. Taking into consideration of the actua l situation, this paper utilized the sensor to acce ss to environmental information and then designed the fuz zy control circuit, aiming to carry out fuzzy contr ol for the operating conditions of solar LED pest control ligh t. Based on the phototaxis of targeted pests, it ad opted the strobe light way to reduce power consumption and save ener gy, thus extending the working hours in the rainy d ays.
