The A1 radar sensor from ACCONEER is a low power, high precision, pulsed short-range radar sensor with a footprint of only 29 mm2. The A1 radar sensor is delivered as a one chip system in package (SiP) solution with embedded radio and antenna. The small size and low power consumption are ideal for integration into compact battery-driven and mobile devices. The A1 radar sensor from ACCONEER is based on a unique patented technology enabling millimeter accuracy with very low power consumption. By operating in the 60 GHz unlicensed ISM radio band, the radar sensor provides robust performance without interference from noise, dust, direct or indirect light. The A1 radar sensor can detect multiple objects at close range with single measurements as well as continuous sweeps set to any frequency up to 1500 Hz. The unique characteristics of the A1 radar sensor make it possible to identify materials and detect motion in advanced sensor applications.
