Gravity: Digital PIR (Motion) Sensor - PIR motion sensor

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.

Energy-saving 24 GHz sensor LD2410S based on FMCW technology and the Doppler effect, designed to detect human presence and micro-movements in real time. Thanks to the built-in AI algorithm and a range of up to 8 meters and a wide detection angle (±60°), it is perfect for building automation, smart lighting and IoT devices. It supports UART and GPIO interfaces, offers very low power consumption (from 0.04 mA in standby mode) and allows configuration through intuitive tools, making it ideal for integration in modern projects.
