After the development of a Data Acquisition System that was wired to a laptop and depended on software running on the laptop. I wanted to develop a system that could function autonomous without being wired to a computer. I decided to develop modules based on an Arduino Uno Wifi making it easy to ad various locations to the network.

The first module I'm working on is designed for a greenhouse with a hydroponic system representing a Life Support System. It monitors various arial parameters in the greenhouse laboratory and aquatic parameters in the hydroponic system. It measures the temperature, air pressure and humidity in the greenhouse and monitors the air quality and presence of hazardous gasses. The sensors in the hydroponic systems monitor the water temperature, pH and water level. All parameters can be viewed in real-time by opening the onboard webpage on the Arduino board. The webpage is a small html page that is coded on the Arduino board.

Coding a html page on the Arduino board has it's limitations but is enough to quickly view the parameters. At this moment to reduce the space the html code uses i coded a static web page on the Arduino board. When the web page is opened it displays the systems status at that moment. In this manner there is still space left for more sensors and links to other modules. This makes it easy to quickly view sensordata on various locations through a webbrowser. Besides the onboard web page I'm going to use MQTT to send the data of the various modules to a centralized location where all data can be viewed on a central dashboard

One of the next steps will be connecting a SD card module for data logging and to store a larger web page. Storing the web page on a SD card will also free up space on the Arduino board for more sensors and will make it possible to code a dynamic webpage displaying the actual sensor data in real-time.
