DISTRIBUTION LIST 1 * Microwave Motion Sensor 1 * Ocean Interface JST 3-Pin Cable ## Features - The microwave motion sensor is a microwave moving object detector designed by the principle of Doppler radar. Unlike ordinary infrared detectors, microwave sensors detect the movement of objects by detecting the microwaves reflected by the object. The detection object will not be limited to the human body, but there are many other things. - Non-contact detection; Adapts to harsh environments without affecting by temperature, humidity, noise, airflow, dust, light, etc. Powerful anti-RF interference capability; Low output power, no harm to human body; Long detection distance. - Can detects of non-living objects; The microwave moves at the speed of light with great directionality. Compatible with Raspberry Pi and Arduino Board. - Used in industrial, transportation and civil applications such as measuring, liquid levels, automatic door motion detection, automatic washing, production line material detection and car reversing sensors etc. - Note: There are ultra-high frequency MOS devices inside the microwave motion sensor. If you try to use battery power to test during the test, this can avoid the breakdown caused by the static pressure difference between the power supply and the test device, such as the oscilloscope; in addition, when the product is in use, Please try to choose battery power supply to ensure the best detection effect. ## Technical Specifications | Specification | Value | |---------------|-------| | Asin | B089NKGWQQ | | Best Sellers Rank | #1,740 in Single-Board Computers | | Date First Available | 1 July 2020 | | Item Model Number | CQRSENWB01 | | Manufacturer | CQRobot | | Product Dimensions | 10.5 x 7.2 x 1.8 cm; 41 g | ## Product Details - **Brand:** CQRobot - **Colour:** White, black or grey - **Item weight:** 0.04 Kilograms - **Maximum range:** 16 Meters - **Power source:** Battery Powered ## Images ![CQRobot Ocean: 10.525GHz Doppler Effect Microwave Motion Sensor Compatible with Raspberry Pi and Arduino Board. for Industrial, Measurement, Automatic Doors, Sensor Lights, Reversing Radar, etc. - Image 1](https://m.media-amazon.com/images/I/61smUsasziL.jpg) ![CQRobot Ocean: 10.525GHz Doppler Effect Microwave Motion Sensor Compatible with Raspberry Pi and Arduino Board. for Industrial, Measurement, Automatic Doors, Sensor Lights, Reversing Radar, etc. - Image 2](https://m.media-amazon.com/images/I/718+aRWgcHL.jpg) ![CQRobot Ocean: 10.525GHz Doppler Effect Microwave Motion Sensor Compatible with Raspberry Pi and Arduino Board. for Industrial, Measurement, Automatic Doors, Sensor Lights, Reversing Radar, etc. - Image 3](https://m.media-amazon.com/images/I/81T2y3HWUYL.jpg) ![CQRobot Ocean: 10.525GHz Doppler Effect Microwave Motion Sensor Compatible with Raspberry Pi and Arduino Board. for Industrial, Measurement, Automatic Doors, Sensor Lights, Reversing Radar, etc. - Image 4](https://m.media-amazon.com/images/I/813f+eZP9DL.jpg) ![CQRobot Ocean: 10.525GHz Doppler Effect Microwave Motion Sensor Compatible with Raspberry Pi and Arduino Board. for Industrial, Measurement, Automatic Doors, Sensor Lights, Reversing Radar, etc. - Image 5](https://m.media-amazon.com/images/I/81+m3TA0adL.jpg) ## Questions & Answers **Q: I reversed the power input. caught the mistake within 5 seconds, disconnected. now the amber detection light stays on always. did i fry it?** A: Hello! You can try to adjust the potentiometer on the back of the sensor (turn it clockwise to decrease the sensitivity), it may be that the sensitivity is too high, causing the detection light to stay on. **Q: can this be used with a 24vt power supply to power a light bar? needing repeat motion detection in a warm enviroment 100-118 degrees** A: No, max voltage is 5V. Also the output would not drive a LED light bar. You would have to use a relay. **Q: Is there any way to disable the visible light on it?** A: hi, friend This product cannot disable visible light. Sorry, it did not help you! Sincere regards! **Q: Battery power is better then mains power?? Am i understanding the product info correctly?** A: Hello! The working voltage of this product is: 3.3V/5V, which is generally connected to the power supply interface of the single-chip main board, and the single-chip main board is responsible for the power supply. Generally, the output voltage of the single-chip main board is 3.3V/5V.

Kan onzichtbaar opgesteld worden . ### ⭐⭐⭐⭐⭐ N/A *by on Reviewed in Canada 14 May 2025* It does what it suppose to do ### ⭐⭐⭐⭐⭐ Un mini doppler, détection au travers des murs *by on Reviewed in France 27 August 2020* J’adore les composants CQRobot. Ils sont innovants, faciles à utiliser.Ce radar fonctionne à merveille pour détecter une présence au travers d’une porte par exemple. il se branche avec 3 fils au niveau de l’arduino, comme un détecteur infrarouge. Sauf que celui là est plus précis et permet de détecter les mouvements au travers des objets / mursL’emballage du kit est super soigné avec emballage antistatique et boite en plastique pour éviter au module d’être écrasé pendant le transport.A acheter les yeux fermés, c’est de la très bonne qualité. ## Frequently Bought Together - CQRobot 10.525GHz Doppler Effect Microwave Motion Sensor Compatible with Raspberry Pi and Arduino Motherboard. for Industrial, Measurement, Automatic Doors, Smart Lights, Reversing Radar, etc. - Stemedu 5PCS RCWL-0516 Motion Detection Sensor, Microwave Radar Sensor Switch Module for Arduino ESP8266 Nodemcu Wemos for Animals Detector, Detection Distance 5-7m, Better Than HC-SR501 - HiLetgo 3pcs HC-SR501 PIR Infrared Sensor Human Body Infrared Motion Module for Arduino Raspberry Pi --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.in/products/313857553-cqrobot-ocean-10-525ghz-doppler-effect-microwave-motion-sensor-compatible](https://www.desertcart.in/products/313857553-cqrobot-ocean-10-525ghz-doppler-effect-microwave-motion-sensor-compatible) --- *Product available on Desertcart India* *Store origin: IN* *Last updated: 2026-08-25*
