The LD2410C is a 24 GHz mmWave radar module that detects human presence, including people who are sitting still, which PIR motion sensors miss. It reports moving and stationary targets separately over a serial UART connection, so it suits DIY home automation rather than plug-and-play use. It is a bare module: you supply power, wiring and a controller such as an ESP32 or Home Assistant setup. Compared with PIR sensors it detects stillness far better, but it needs configuration and has a narrower detection pattern than a wide-angle PIR.

Owners of LD2410-series modules generally rate them as reliable still-presence detectors for DIY automation, with the caveat that setup and tuning take effort.
This set includes three LD2410C human presence sensor modules. Each one is a radar sensor module.
The modules are made of heat-resistant engineering plastic. Each module measures 5.5 x 3.5 x 1.6 in (14 x 9 x 4 cm).
