Circuit Documentation

Summary

This circuit is designed to harness solar energy to power an ESP8266 NodeMCU microcontroller and various sensors. The solar panel charges a 18650 Li-ion battery through a charge controller. The voltage regulator ensures a stable voltage supply to the microcontroller and sensors. The ESP8266 NodeMCU reads data from a turbidity sensor and multiple DS18B20 temperature sensors, which are connected via a 1-Wire interface.

Documented Code

There is no code provided for the microcontroller. The documentation of the code would typically include details on how the ESP8266 NodeMCU is programmed to read from the temperature and turbidity sensors, process the data, and possibly send it to a remote server or display it locally. However, since no code is available, this section cannot be completed.
