Embodiment 1
[0038] (1) Monocrystalline silicon flexible solar panels are selected as solar cells (operating voltage 18V, current 1.11A, power 20w, conversion efficiency 22%); batteries use Zhongshun core polymer lithium batteries (12V, 20AH);
[0039] (2) Select TELESKY LM2596S-ADJ adjustable step-down and stabilized power supply module for voltage conversion, which plays the role of voltage stabilization and limiting; the small fan selects working parameters as power 3-4w, input voltage 5V, and working current 0.5A-1A.
[0040] (3) Use the DHT-11 temperature and humidity sensor to detect the ambient temperature; use the HC-SR501 human body infrared sensor to sense whether there are passengers in the car. Use ATmega16 microcontroller as microcontroller to receive sensor data, and control the fan through the SRD-05VDC-SL-C optocoupler. When the person stays in the car and the temperature inside the car is high, the fan is controlled to rotate and the air supply device is turned on. Realize...
