VIN 4 – 28V supply voltage CDS LDR 10-20k RL, U_LDR > 0.7V = On (Enable control chip)UpgradedRCWL-0516 updated version 15M Microwave Doppler Radar Sensor Switch Module Human Induction Board Detector for Arduino Description: 100% brand new and high quality RCWL-0516 is a technology that uses radar Doppler, microwave induction special module for detecting moving objects. Feature: high sensitivity, induction distance, high reliability, induction Angle is large, voltage supply range and other characteristics Widely used in all kinds of human body induction lighting and anti-theft alarm, etc. Wide operating voltage from 4.0 V to 28.0 V Compared to traditional infrared PIR sensor, penetration detection capability Locking time, the distance is adjustable The output of 3.3 V power supplyData linkhttps://circuits4you.com/2018/10/23/rcwl-0516-radar-sensor-interface-arduino/ https://www.electromaker.io/tutorial/blog/using-a-doppler-radar-sensor-with-the-raspberry-pi-12 https://github.com/jdesbonnet/RCWL-0516FAQQ: I wired this up on a breadboard and was only able to get a .17-.18 volt output, not enough to trigger a 3V 12000Rpm Thick Coin Vibration Micro Motor... Could you please tell me what the problem is, I have tried multiple units and get the same result... Could there be a problem with the batch I got? A: The output is logic only, it cannot drive any load The output can only be read by an AVR or MCU, and certainly not drive a motor or any other kind of load So, you should read the output state with an AVR or MCU (for example arduino) and drive the load from the arduino with a transistor or mosfet Q: What is the frequency of the raddar signal? A: This radar module works at 5.8GHz Q: Is there a way to determine c-tm, r-gn, or r-cds without using trial and error? A: You can refer to this page https://www.electroschematics.com/get-started-microwave-radar-motion-sensor/ Q: How much power (w) does the load cell consume? A: The consumption is about 1500uA (1.5mA), and 0.5uA in power down mode Q: Will this detect motion through glass? If I place the sensor in a glass jar (outdoors, so the glass jar it for it's protection) will it still work? A: Yes. It will sense motion through most anything. The more shielding there is, the less detection range you get. I can detect motion through drywall walls, ceilings and floors. Very sensitive. You might have to filter the power supply. There are tutorials. Q: Do these sensors can detect non-animal/human objects like wood, plastic etc.? A: The RCWL module can detect inert object at the condition that it has enough density, volume and it is in motion. So if the wood, plastic can meet these requirement, it can detect Q: If used outdoors, will the Stemedu RCWL-0516 Motion Detection Sensor detect vegetation moving in the wind, or is it selective for animals and humans? A: Yes, it can detect. The RCWL module can detect inert object at the condition that it has enough density, volume and it is in motion. So if the wood, plastic can meet these requirement, it can detect Q: Will heavy rain set this off or snow? A: The rain or snow can be detected, but cannot say for sure wether the sensitivity threshold is high enough to avoid it Q: What are the differences between this and Google's Soli chip? A: Google Soli chip is used for short distance to detect finger motions for scrolling etc While this motion sensor is used to detect presence of Object in a room etc Q: How close together may 2 or more of these be placed without interfering with each other? A: It is not advised to use two close than 10 meters They may not interfere, but they may interfere, it totally depends on the tunning, which is a little random on this module Q: Any suggestions on how to increase the "out" voltage/drive. need 5v to trigger relay board. i saw a board mod but was too small to read." A: The output voltage is 3.3V, 100mA, it can not be increased.
