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 ΅A, letting the sensors run for two years on standard alkaline cells.
The Beam Store from Suitable Technologies is managed by remote workers from places as diverse as New York and Sydney, Australia. Employees attend to store visitors through Beam Smart Presence Systems (SPSs) from the company. The systems combine mobility and video conferencing and allow people to communicate directly from a remote location via a screen as well as move around as if they are actually in the room.
An MIT research team has invented what they see as a solution to the need for biodegradable 3D-printable materials made from something besides petroleum-based sources: a water-based robotic additive extrusion method that makes objects from biodegradable hydrogel composites.
