- Abstract
Agricultural monitoring devices are electrically powered, but agricultural areas are broadly spread out geographically where electricity supply is not often available, hence the need for solar charger is clear. In this paper polycrystalline silicon solar energy cell boards are designed to be controlled through a LM2596 switching regulator modules. Output voltage and charging status from a Holzer current sensor are detected by using SCM STC89LE52RC and analogue-to-digital conversion chip ADC0832. The collected data are processed and displayed on an LCD screen. Experimental tests show that the charger can be used for normal USB charging, real-time voltage and current parameters are displayed on the LCD during charging, at the start and finish with interim state of charge indicated through the LED.
