Integrated processing and control of multiple environmental variables through internet of things (IOT) using cots components

Nowadays, there is a growing need in various research fields and the produce and precision agricultural industry to record and process data from multiple sensors, sensors sometimes located in remote areas, miles apart from each other. The usual approach to sensor data recording implies separate measurement equipment for each variable, making difficult and expensive the integration and processing of joint data. An affordable solution is here proposed, providing with an integrated multivariable measurement environment, using commercial-off-The shelf (COTS) and taking advantage of the ubiquitous computing capabilities available today, in what is generally known as Internet of Things. The proposed system was successfully tested as a monitor of a microalgae culture used for biofuel research applications. Multiple variables (temperature, light, pH and dissolved oxygen) associated to microalgae kinetic growth are captured and sent to a remote database that is connected to Internet, where researchers can perform various data analysis online.
