This is a device that it monitoring the performance of a set of solar panels that are charging a lithium polymer cell. A Raspberry Pi is used to collect data using a TSL2561 lux sensor and solar and battery voltage is monitored with an ADS1115 4 channel A
Solar Heaters (3 different boxes that were a science project) are connected in series and are being used as a supplemental heat source for my bedroom. I am using 4 DS18B20 sensors, 1 DHT11, a servo, and 3 fans. These are all being controlled by NodeMCU.
