Particle size division collection method of multi-stage cloud and mist water collector

The invention relates to a particle size division collection method of a multi-stage cloud and mist water collector, and belongs to the technical field of environment detection, and the method comprises the following steps: installing a sample collection system and a weather detection system of the multi-stage cloud and mist water collector on site; the weather detection system detects weather conditions through simultaneous work of a miniature fog detector, a rain and snow existence sensor, a rainfall sensor and a temperature and humidity sensor; according to the detected weather condition, the sample collection system is automatically started or closed, and the automatic controller receives a signal of the weather detection system and controls the rainwater interception part and the multi-stage cloud and mist water interception part to work, so that collection according to particle sizes is realized; samples collected according to particle sizes are stored in the sample storage chamber; after collection is
