This is the development of a low-cost weather station. Low cost is related to power consumption and project cost. The components used in this project are relatively cheap for regular customers costing around 5-6 dollars the total price. In terms of power consumption, the code has been developed to consume the minimum energy as possible using deepsleep mode provided by ESP8266. For now, this weather station is capable to measure just temperature and humidity with high accuracy and save data in an SD CARD but new features will be appended to the project in the future.
