3、 realize the automatic tracking solar light and control the charging and discharge. Solar intelligent control device can automatically detect the battery voltage, when the battery is less than 30%, solar intelligent control device can control the battery to stop foreign discharge. The system is main
4、ly based on STC89C52, ADC0809, 28BYJ-48 stepper motor, photosensitive resistance as the core, the use of PWM signal to control the charging and discharging, effectively prevent overcharge, prolong the service life of the battery. The use of optical detection of photosensitive resistance direction, simple principle, easy to use, and has great practical value.
