{"product_id":"mikroe-2814","title":"Solar energy click","description":"\u003cp\u003eThere are many battery chargers and solar energy harvesters out there already, but the \u003cstrong\u003eSolar energy click\u003c\/strong\u003e has the unique feature - it encompasses both of these devices in a single package. The click uses Texas Instruments \u003ca href=\"https:\/\/download.mikroe.com\/documents\/datasheets\/bq25570.pdf\"\u003eBQ25570\u003c\/a\u003e - a nano-power high-efficiency boost charger and buck converter device, designed to work with very low power energy harvesting elements, such as the photovoltaic and thermoelectric generators.\u003c\/p\u003e\n\u003cp\u003eThe \u003cstrong\u003eSolar energy click\u003c\/strong\u003e recharges the connected LiPo battery or the onboard 220mF supercapacitor, using the photovoltaic element.This is done by utilizing the BQ25570's charging and power harvesting capabilities and clever nano-power management features. This click can also power up low power consumption devices by using the stored energy, providing a way for continuous power operation of low power devices.\u003c\/p\u003e\n\u003cp\u003eThese features make the \u003cstrong\u003eSolar energy click\u003c\/strong\u003e an ideal solution for powering wireless sensor networks, environment monitoring devices, portable and wearable health monitoring devices and similar low power self-sustained devices.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eHow does the click work?\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eThe click is equipped with BQ25570, nano-power high-efficiency boost charger and buck converter device, designed to work with very low power energy harvesting elements. It can both provide power to the connected external load and charge the LiPo rechargeable battery using the solar panel as the photovoltaic element - employing its energy harvesting capabilities.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/shop.mikroe.com\/img\/cms\/solar-energy-click-inner-img%20(1).jpg\" alt=\"\"\u003e\u003c\/p\u003e\n\u003cp\u003eThe connected load will be powered on either from the connected LiPo battery or the supercapacitor soldered on board. When the battery voltage drops under the 2.85V, the interrupt pin (routed to the mikroBUS™ INT pin) will be driven to a LOW logic state. The integrated nano-power management unit takes care of providing the proper charging conditions for the battery. When the battery is charged up to 3.25V - due to the hysteresis set with the voltage divider resistors - the INT pin will go to a HIGH logic state, once again. Also, thanks to the nano-power management unit, the battery will not get overcharged above 4.06V. The click board™ provides 2.6V\/100mA for the connected external load on the output terminal. \u003c\/p\u003e\n\u003cp\u003eWhen the battery is not connected, the internal supercapacitor will be used as the energy storage element. This is useful for continuous powering up of very low power applications, as the supercapacitor should be able to provide power continuously since it will get recharged by the solar panel before it is drained out by the load. The internal converter will be disabled if the storage element voltage drops under the internally set under-voltage level of 1.95V, preventing the damage of completely draining out the connected storage element.\u003c\/p\u003e\n\u003cp\u003eIn addition to the INT pin, there are two more pins of the BQ25570 routed to the mikroBUS™, used to enable the BQ25570 internal sections (EN) and to enable the power output for the connected load (OUT). Setting the EN pin to the LOW logic level will enable the BQ25570 internal sections and the power charger features, while the HIGH logic level on the OUT pin will enable the power output for the connected load.\u003c\/p\u003e\n\u003cp\u003e\u003ciframe frameborder=\"0\" src=\"https:\/\/www.youtube.com\/embed\/8o9k1cC7v_Y\" width=\"560\"
