HB100 Microwave Doppler Radar Wireless Module Motion Sensor HB100, Microwave Motion Sensor, Motion Detector

hello youtube so today i'd like to talk about this little device here so this is an hp 100 doppler radar uh it's available for a few dollars online uh the reason i'm making this video is because uh i was looking on youtube for you know how to use this with an arduino and uh there's two things i noticed first is a lot of misconceptions out there about this device and people are usually using it wrong and well i don't know how they're getting their readings and stuff but they're not using it properly the second thing is this device is an extremely low power device and it's signal that comes out from its output pin is so low that uh typically the arduino can't even read it so you need to use an external circuit to amplify that signal uh before you can use it effectively on a on a microcontroller like an arduino so uh i just like to talk about this device today and uh demonstrate how it wor
