The EasyBloom plant sensor allows you to measure sunlight, temperature, water drainage and fertilizer. It seems very simple: You pull apart the sensor and plug the USB directly into your computer where you do the initial setup, then you place the sensor into the soil of the plant you would like to monitor, and bam, you get the results and know how to adjust accordingly.
