Tiny sensor cubes promise to have a huge impact on fish farms

According tomedia reports, monitoring the water quality of fish farms is crucial, as pollution and other issues can quickly have disastrous consequences. With this in mind, the researchers designed a small, new floating sensor cube that can keep track of multiple factors. As things stand, fish farm operators typically use multiple water sensors. Each method measures something different, such as oxygen content or acidity, and must be checked manually. Although systems that combine multiple sensors in a single device, they are often large and expensive.

To address these restrictions, scientists at King Abdullah University of Science and Technology (KAUST) in Saudi Arabia created the floating device. Instead of trying to plug all of their functions on a single chip, they used multiple chips connected along the edges to form a cube.

The researchers weighted the gadget so that its integrated solar panels are always facing up to power the battery. Its bottom side contains sensors to measure pH, temperature, salinity and ammonia levels, while the other side contains air pollution sensors and antennas , the latter for transmitting data via Bluetooth to nearby smartphones. If the data is abnormal, the smartphone will immediately alert.

The KAUST team is now developing a cooling system for the equipment to prevent it from overheating in direct sunlight. As you can imagine, cube sensor technology can also be used for other purposes, such as monitoring oil in a pipeline.

A paper on the study, led by electrical engineer Mohammed Hussain, was recently published in the journal Small.
