“I decided show my school work of my own board for weather station based on ESP8266 - 12 with BME280 (as temperature, humidity and pressure sensor) and with photoresistor as detector of sunlight. I add ADC 1115 for get voltage from voltage divider (sunlight measure and voltage from battery).
Pros:
Using solar cell to charge Lithium - ion battery (18650)
Using Wi-Fi to connect ThingSpeak”
