24GHz mmWave Radar Sleep Sensor

This is an innovative, high-quality sleep monitoring sensor from Seeed Studio. With this sensor, you can monitor your respiratory movements during sleep, consequently detecting any potential chronic respiratory disorders. Unlike conventional PIR sensors, this one uses Doppler radar technology. This allows for better performance in detecting human activities and a higher sensitivity. The radar sensor can detect movements of objects through walls and other obstacles, which is not the case with PIR.
