3 individual tracking ids: showing distance - Heat Trail - Heading indicator - Correct distances according to spec. sheet This library https://github.com/javier-fg/Arduino\_RD-03D Was very helpful. Thank you Using the Ai-Thinker RD-03D 24GHz millimeter-wave radar module with a CYD esp32 2.8” The RD-03D can simultaneously track up to 3 moving targets, providing real-time position (X/Y coordinates), speed, and distance information for each target. It is primarily intended for indoor use to track moving human targets. This radar can be used to setup automations for zone interactions. Or giving the ability for a camera to track movement. Or have a fan connected to a servo to follow you. Or interactive led lights that track/follow you and light up in relation to distance. I have about 5 different doppler mmwave radars. And before jumpping into the deep end or $$$ This model rocks for 13$ submitted by /u/GreasyGato [link] [comments]
