Watering System

Monitoring and watering system, that can be used for domestic use on large scale, has been developed. The system is based on the CC3200, which uses FreeRTOS, 3 sensors interfaces have been developed (soil moisture, temperature and humidity ratio, and water level) as well as a way to water the plant via a water pump powered by an external battery and controlled by a relay. A PC application has also been developed consisting of a graphic user interface in which the user can visualize the sensor’s data, both the latest measure as well as a graphic containing the history of the variable. The user interface also allows to water the plant in two ways, normal watering or fixing a temperature and soil moisture threshold, if those thresholds are surpassed the plant will water by itself. Data is also stored in a file on the computer in CSV format, just in case, any further processing is needed. The communication between the PC and microcontroller is wireless and done via Wi-Fi, using MQTT, which makes scaling the project very easy thanks to the publish-subscribe method. Besides, a website has been developed in order to be able to access the data and interact with the system even when not in the same Wi-Fi network.
