A new way of detecting human body and moving object, not PIR, not ultrasound and it is definately not expensive and complex image processing with camera, it is using Radar microwave. And it is quite low cost, you should try it!

Using Doppler radar technology, this is a microwave sensor module specifically for detecting moving objects and human body. The module has many advantages such as high sensitivity, long sensing distance, wide sensing angle, high reliability, wide range of operating voltage. Widely used in human body sensing lighting system, anti-theft alarm system.


  • Working voltage: 4-28VDC
  • Operating current: less than 3 mA
  • Output voltage: 3.3V (from 3V3 pin), Note: Not input power.
  • Output Current: 100mA maximum
  • Detecting range: less than 120 degrees taper angle within 7 meters
  • Trigger mode: repeat trigger
  • Delay time: 2 seconds (the default value), by soldering capacitor in different capacities on C-TM pads to adjust it
  • Active Level: high (when it detects a moving object)
  • Interface:
    • 3V3 (3.3V power supply output), NOT input voltage
    • GND (power ground)
    • OUT (output signal)
    • VIN (power input)
    • CDS (detection can be turned off during the day by soldering an external photoresistor to ground).
    • Only need to use GND / OUT / VIN in general applications.
  • - Application: Automatic lighting, smart home, DIY projects

Packing List:

  • 1 x Microwave Radar Motion Sensor Module


Is this human motion sensor affected by fire?
( M, 21/11/2020 )
Hi, for this product it will not be affected by fire ya. Thanks :)
Good day, it can detect human-only or non-human objects?
the second question, is the voltage used to control the sensitivity?
( Jereme Lee, 17/06/2020 )
Hi, it can detect human body and moving object. The voltage is not used to control the sensitivity. Thanks :)
Does it only detect humans or it can detect objects too? ( Nazwa Najmuddin, 14/02/2020 )
Hi, it can detect human body and moving object. Thanks :)
do you have the programming code for this component?
( Vrindah, 30/03/2019 )
Hi can i get the datasheet for this component? ( Vrindah, 20/03/2019 )
Hi, sorry. We don't have the data sheet for this item.
Hi, Can the output of this sensor direct connect to Maker Uno's digital IO pins directly ? ( zenith tan, 09/10/2018 )
Hi, yes you can connect it directly :) you may refer to this video for more info.
hi, when will this item be restocked? ( muhamad danial, 31/08/2018 )
Hi, this item will available in 1-2 weeks :)
can it be used with espresso lite v2? ( MOHAMAD NASRIZAL HAFIZI MAZLAN, 25/06/2018 )
Hi, yes it can, but you may need Logic Converter 4 Channels between sensor and microcontroller. Thanks.
Hi, is there any tutorial to interface this with arduino uno? ( Danial, 15/05/2018 )
Hi, we believe there have tons of example in Google. For example, you may refer to this link. For further questions, please visit to our technical forum for similar question or post your question there, as this session is only for short inquiry. Thanks.
