We’ve just written about an ESP32 UWB board equipped with an ultra-wideband module designed for indoor positioning with about 10 centimeters accuracy, which should be good enough for many applications, but it turns out UWB sensors can be made to be much more accurate. NOVELDA has just announced the UWB X4/X4F103 sensor and development kit that can detect submillimeter micro-movements such as breathing for human presence detection and does so at a really low power consumption of under 2mW. NOVELDA UWB X4 (X4F103) highlights: High-precision ranging for accurate distance measurement and absolute range bounding based on patented impulse radar technology Low power consumption below 2mW, and no co-existence issues with other sensors Wide detection zone for accurate detection with up to 180-degree field of view Up to 5m range Works through plastic and glass or layers of clothing Package – 12 x 12mm sensor A big difference compares to Decawave […]
