Circuit Documentation

Summary

This circuit involves an Arduino UNO microcontroller interfacing with a thermistor, a humiture sensor, and a barometer. The sensors are connected to the Arduino to measure temperature, humidity, and atmospheric pressure. The Arduino processes the sensor data and can be programmed to perform various tasks based on the sensor readings.
