The GR10-30 sensor module, which can recognise up to 12 user gestures from a distance of up to 30 cm. It supports communication via both UART and I2C interfaces. DFRobot SEN0543

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

Air speed sensor module based on the FS3000-1005 chip. The board is equipped with Qwiic connectors. SparkFun SEN-18377

A compact FIR temperature sensor enabling high-precision, non-contact measurement of objects. The medical version offers an accuracy of ±0.2°C over a range of 35 to 42°C, and in extended mode, it measures temperatures from -20°C to 100°C. The sensor communicates via I2C and is mounted on a STEMMA QT board with an integrated voltage regulator for easy integration with 3V and 5V microcontrollers. Adafruit 6403

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

A 24 GHz FMCW radar with Wi-Fi 802.11b/g/n and Bluetooth 5.0 BLE support, enabling precise detection of motion and human presence. Equipped with an integrated detection algorithm and a RISC processor with SPI, UART, I²C, PWM, and GPIO interfaces, it provides flexible configuration and reliable communication in IoT systems. With a wide operating temperature range (-40°C to +85°C), a built-in radar antenna, and WPA3 support, the module is ideal for smart homes, building automation, and security systems.
