I’m looking to use a Radar Module (RD-01) to fade in and out (on/off) some led light strips when someone enters or leaves the room. I’m planning on modifying a Sonoff to use a SSR for supplying mains ac to a 12VDC lighting transformer but I also think that I’d need to PWM the 12V to fade in/out the strips. I haven’t found much info on these Radar Modules (RD-01) but I think that they look very good as they have both Wi-Fi & Bluetooth onboard which is handled by a 32-bit RISC CPU (BL602). To be honest I’m not 100% sure that I need the Sonoff device to handle the mains electricity as I could just design my own PCB for this purpose but I just thought that I’d ask on here if anyone has any experience of using these Radar Modules. Thanks in advance.
