The Walabot Starter is a small, programmable sensor tool that looks into objects using radio frequency technology sense the environment, bringing highly sophisticated sensing capabilities to your fingertips. This Walabot Starter version uses a three-antenna array to illuminate the area in front of it and sense the returning signals. The signals are produced and recorded by a VYYR2401 A3 System-on-Chip integrated circuit. They are then communicated to a host device (like your phone or computer) using a USB interface, which is implemented using a Cypress controller.
Through broadband recordings from multiple transmit/receive antenna pairs, the Walabot Starter is able to analyze and reconstruct a two-dimensional image of the environment. Analysis of sequences of images allows detecting changes in the environment. The Starter version is capable of basic range measurements and breathing pattern detection, and includes a micro-B to micro-B USB cable.
