Electronics technology is helping farmers and gardeners make more effective use of water by determining when it's time to turn on irrigation equipment. The Acclima Digital TDT Soil Moisture Sensor reads the absolute volumetric water content along with soil temperature and soil conductivity. The instrument converts its many digital inputs to analog output using an increasingly common technology, incorporating the converters onto a microcontroller. Texas Instruments' MSP430F155 holds two DACs that are integral to the digitizing function. That integration helps keep current draw under 15 µA, letting the sensors run for two years on standard alkaline cells.
A simple new chemical method for repairing and recycling notoriously difficult carbon fiber composites has been developed by the Fraunhofer Institute for Applied Polymer Research. An entire component can be completely recycled, including reclaiming its expensive carbon fibers for reuse.
In today’s connected world we are seeing the beginning of connected homes, smart grids, self-driving automobiles, drones, and many other amazing devices. Out of all the soon-to-be connected devices, which device poses the greatest dangerous to its users and society?
