Inspiration
We are developing a passive, biodegradable nitrogen or pH sensors for use in agriculture. Having the right soil conditions can multiply crop yield and ensure that plants stay healthy. Furthermore, different plants need different soil conditions to thrive and soil conditions can vary across a farm so having a cheap way to measure pH and/or nitrogen can help farmers efficiently and effectively use fertilizers.
How it works
Our product is a capacitor that changes capacitance based on the pH or nitrogen levels in soil. We will be using a hydrogel that changes volume based on pH or nitrogen levels. As the hydrogel changes in volume, the capacitance will change, shifting the resonant frequency of its mother circuit. This change in frequency can be probed externally and without disturbing the soil.
