The technology firm AgriHouse has figured out a way to let plants send text messages when they need more water, IEEE Spectrum reports. The tiny sensors clip onto plant leaves and calculate the plants moisture. Then, when the plant gets too dry, the sensors a text the farmers. I envision it probably saying something like this:
OMG, I needs drink, pls.
Considering the roughly 129 billion liters of water consumed every day by commercial agriculture in the United States, AgriHouse believes the sensors could make a dramatic difference in agricultural water consumption.
