Take a quick look at a battery-free Wi-Fi 6 sensor device created by Sigma Connectivity. The board makes use of Silicon Labs energy-efficient SiWG917Y module to power the sensor using solar panels utilizing Wi-Fi 6's Target Wake Time (TWT) feature to reduce power consumption. Regular temperature, humidity and pressure readings are taken and sent over Wi-Fi.
