@ubuntu.maniax: humans, 1 radar, 0 wires 📡 24GHz mmWave radar (RD-03D) tracking 3 moving targets in real time — distance, position, speed. Wireless sensor node: XIAO ESP32-S3 reads the radar, streams target data over UDP to an Arduino Giga R1, which renders it live. FMCW radar only sees movement — no Doppler shift, no detection. #mmwaveradar #esp32 #arduino #embeddedsystems #iot hardwarehacking maker electronics radar wifi udp embedded diyelectronics
