Its compact 24x28mm form factor and dual output options make it ideal for seamless integration into smart homes, autonomous vehicles, and industrial automation. Built to withstand extreme temperatures (-40 to 85°C) and environmental interference, this sensor ensures reliable, high-precision detection in any setting. ## Description Introduction This 24GHz millimeter-wave radar sensor employs FMCW, CW multi-mode modulation and separate transmitter and receiver antenna structure. In working, the sensor first emits FMCW and CW radio waves to the sensing area. Next, the radio waves, reflected by all targets which are in moving, micro-moving, or extremely weak moving state in the area, are converted into electrical signals by the millimeter-wave MMIC circuit in the sensor system. After that, these signals will be sent to the processor and processed through the related signal and data algorithms. Then, the target information can be solved out. The millimeter-wave radar can sense the human presence, stationary and moving people within the detection area. Moreover, it can even detect static or stationary human presence such as a sleeping person. There are two ways provided to output detection result: serial port and I/O port switch quantity. Besides that, the sensor module features strong sensing reliability, high sensitivity, small size, easy to be used or embedded in applications. Specification Power Supply: 3.6~5V Operating Current: 90mA Detection Distance: 9m Equivalent Transmit Power: 9-12dBM Beam Angle: 100*40° Modulation Mode: FMCW, CW Operating Frequency: 24GHz Operating Temperature Range: -40~85℃ Baud Rate: 115200 Dimension: 24*28mm/0.94*1.10" Shipping List mmWave - Human Presence Detection Sensor (9 Meters) ×1 ## Features - 【24GHz High Precision Stillness and Motion Detection】: With the Doppler radar technology and 24GHz working frequency, combined with FMCW and CW multi-mode modulation, this mmWave Radar sensor can accurately detect all movements, micro-movements, and extremely weak movements within a 9-meter range. Whether it's subtle human movements or stillness and sleep states, this sensor can accurately perceive them. - 【Compact Size, Easy to Integrate】: The mmwave sensor's size is only 24*28mm, and it uses a 1Tx1Rx antenna structure, which is very suitable for integration into various systems or mobile devices, providing great convenience for various projects. - 【Strong Anti-interference Ability (From -40 to 85℃)】: This mmwave presence sensor has outstanding anti-interference ability and can work stably in an environment of -40~85℃. Whether it's snow, fog, haze, temperature, humidity, dust, light, or noise, none of these can affect its working efficiency, ensuring stable performance in any environment. - 【Wide Range of Application Scenarios】: Due to its high precision and strong anti-interference ability, this presence sensor is widely used in collision warning for autonomous driving cars, human activity monitoring in smart homes, precise control in industrial automation, non-contact monitoring in healthcare, inventory management in retail and logistics, obstacle avoidance and positioning in drones. - 【High Flexibility with Various Output Options】: This human presence sensor provides two types of sensing result output methods. You can choose to output through the serial port or through the I/O port, which is very flexible and easy to expand. At the same time, it provides various available example codes that can meet the needs of makers in different projects. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0BYMYMXLP | | ASIN | B0BYMYMXLP | | Antenna Location | Driveway, Garage, Garden, Lawn, Sidewalk, Terrace, Walkway | | Battery Description | Battery not included | | Best Sellers Rank | #55,087 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #122 in Motion Detectors | | Brand | DFROBOT | | Built-In Media | mmWave - Human Presence Detection Sensor (9 Meters) | | Color | Black | | Compatible Devices | Various Devices | | Customer Reviews | 3.6 3.6 out of 5 stars (2) | | Customer reviews | 3.6 3.6 out of 5 stars (2) | | Date First Available | 1 April 2023 | | Frequency | 24 GHz | | Item Dimensions D x W x H | 28D x 28W x 28H millimeters | | Item Type Name | motiondetectordevice | | Item model number | SEN0395 | | Manufacturer | DFROBOT | | Manufacturer | DFROBOT | | Maximum Range | 9 Meters | | Mfr Part Number | SEN0395 | | Model Number | SEN0395 | | Mounting Type | Internal Mounting | | Number of Items | 1 | | Power Source | Corded Electric | | Product Dimensions | 2.4 x 2.8 x 0.35 cm; 10 g | | Temperature Range | 85 Degrees Celsius | | Unit Count | 1.0 Count | | Upper Temperature Rating | 85 Degrees Celsius | ## Product Details - **Brand:** DFROBOT - **Colour:** Black - **Maximum range:** 9 Meters - **Mounting type:** Internal Mounting - **Power source:** Corded Electric ## Images ![DFROBOT mmWave Radar - Human Presence Detection Sensor (9 Meters) - Image 1](https://m.media-amazon.com/images/I/61rCcvYxIoL.jpg) ## Available Options This product comes in different **Model** options. ## Frequently Bought Together - DFROBOT mmWave Radar - Human Presence Detection Sensor (9 Meters) - EC Buying LD2410C Sensor Module HLK-LD2410 Human Presence Radar Sensor Module LD2410 Millimeter Wave Radar Sensor Module Non Contact 24GHz ISM Band Serial Port IO Level Output --- ## 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.no/products/525419274-dfrobot-mmwave-radar-human-presence-detection-sensor-9-meters](https://www.desertcart.no/products/525419274-dfrobot-mmwave-radar-human-presence-detection-sensor-9-meters) --- *Product available on Desertcart Norway* *Store origin: NO* *Last updated: 2026-09-25*
