PMW3901 Optical Flow Sensor - module with an optical motion sensor

HLK-LD2450 is a 24 GHz radar module designed for precise human presence and motion detection in intelligent IoT systems. modHLK-LD2405

Advanced 60 GHz radar, capable of detecting human presence, falls, posture and vital signs such as heart rate and breathing – even when motionless. Ceiling-mounted and compatible with platforms such as Arduino or ESP32, it is ideal for healthcare systems, especially for monitoring sleep and the safety of the elderly. DFRobot SEN0623

PIR motion sensor module for Arduino and Raspberry Pi. DFRobot SEN0018

The MR60BHA2 sensor kit uses 60GHz mmWave technology to reliably detect human presence, as well as human breathing and heartbeat detection. It offers Home Assistant integration thanks to the XIAO ESP32C6 module and pre-installed ESPHome firmware. Equipped with a BH1750 light intensity sensor, RGB LED indicator and the possibility of expanding with Grove sensor modules, it is ideal for monitoring health, safety and home automation.

Occupancy sensor based on 24 GHz millimeter wave technology with FMCW, enabling precise detection of people, measuring distances up to 25 m and movement speed. Thanks to high resistance to environmental interference, it works reliably in conditions such as dust, light or temperature changes, outperforming traditional PIR and ultrasonic sensors. Compact size and installation flexibility make it perfect for intelligent lighting, security systems and building automation. DFRobot SEN0609

Module with PIR EKMC4607112K motion sensor, power consumption in standby mode up to 170 uA. SparkFun SEN-17372

A digital shock sensor that detects hand shake. The spring-type vibration switch allows you to output pulses when the user shakes once in a certain direction. DFRobot SEN0289

Module with a PIR motion sensor designed for M5Stack modules. It can detect movement up to 5 meters with a detection angle of 100 degrees. M5Stack U004

This is a simple to use motion sensor. Power it up and wait 1-2 seconds for the sensor to get a snapshot of the still room. This unit works great from 5 to 12V (datasheet shows 12V). You can also install a jumper wire past the 5V regulator on board to make this unit work at 3.3V. Sensor uses 1.6mA@3.3V. SEN-13285

Module with a motion sensor that uses the Doppler effect to detect moving objects using microwaves. It is powered with the voltage of 5 V and has a digital output (Gravity connector). DFRobot SEN0192

Module with PIR EKMC4607112K motion sensor, power consumption in standby mode up to 170 uA. The board communicates via I2C and is equipped with a Qwiic connector. SparkFun SEN-17374

Gravity: 360 Degree Hall Angle Sensor is a rotation angle sensor measuring a value in the range of 0-360 ° with an analogue output, powered by 5V. DFRobot SEN0221

HLK-LD2410C is a 24 GHz radar sensor for human presence and micro-motion detection, featuring UART and BLE interface. modHLK-LD2410C

Module with PIR S16-L221D motion sensor. The board is equipped with a Grove connector and communicates via a digital interface. Seeed Studio 101020617

Module with a human presence and movement sensor designed based on the STHS34PF80 infrared sensor. Enables monitoring of radiation and ambient temperature within an 80° field of view. The sensor can precisely detect movement and presence within a range of 4 m. It uses the I2C or SPI interface for communication and has built-in Qwiic connectors. SparkFun SEN-22494
