AM-HB100 Doppler Radar Speed Detector

AM-HB100 Doppler Radar Speed Detector  

This unique little device is useful accurate method for detecting change in velocity using the Doppler effect, commonly known as a radar speed gun. Requires additional circuitry for amplification of the signal, in attachments the datasheet has some amplification circuits. Feed the output of the amplifier to any Arduino microcontroller and essentially build your own radar gun! Do not remove the metal covering as it will affect the RF circuits inside and DO NOT connect this unit as is into any microcontroller as the RF signal requires amplification and filtering.
