Solar monitoring system measures voltage, current and power from panel, and from two outputs and voltage on battery.
This board measure input voltage, current and power from two sources. Board have two outputs. Each have voltage, current and power measuring. Voltage, current and power measure with INA219 board from Adafruit. Input from solar panel is completely isolated from ESP8266 and 5V. Every inputs and outputs have 3A fuse. I measure temperature and humudity inside box with AM2301 and measure heating temperature with termocoupler and MAX6675. I2C bus is connected via level shift converter to ESP board.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
