This sensor is applied in many radar products on the market. Needs amplification circuit that can be found all over the internet when googeling on HB100. The application note found at https://github.com/10to7/X-BandMotionDetector/tree/master/Reference is very helpfull.
This board requires additional circuitry in order to use. Needs an op amp stage in order to get sufficient gain. The IF output is very low (mv) and the output freg. changes (30 ~ 300 Hz) depending on what is sensed by movement in front of the sensor. You can't tell much by just using a voltmeter on the output, a scope shows more of what's is really going on. There are Youtube videos that show how to use this sensor...
I have only tested three but they all worked as expected. It seems to be the same sensor which you can find in many automatic doors and such. I am really happy with these, have added them to a robot and to turn on/off lights when entering/exiting a room.
Ce petit détecteur hyperfréquence est un excellent partenaire au kit IRP [SKU: SKU159324] . En farfouillant un peu sur le net vous trouverez de quoi ravir votre curiosité et piquer votre envie de créer d'autres montages tout aussi futiles, qu'utiles ou amusants grâce à ce petit module. La seule limite c'est vous ! This small microwave detector is an excellent partner IRP kit [SKU: SKU159324]. Rummaging a bit on the net you will find plenty to delight your curiosity and pique your desire to create other arrangements equally futile than useful or fun with this little module. The only limit is you!
i bought it but any intruction i dont know what i can do it with it (-
got it for a speed gun, not used yet
Got the product on time. not used as of yet since it is not plug n play as it requires an amplifier circuit to go with it!!!
Das Modul bedarf einer für solche Module relativ komplexe Schaltung zum Filtern der Ausgabesignale. Wenn man die jedoch einmal gelötet hat, funktioniert es gut.
Good motion sensor small size (45 * 37 mm), with a standard power on 5V.
