🚩 This RCWL-0516 module has the characteristics of high sensitivity, high induction distance, high reliability, large induction angle, wide power supply voltage range, etc. it is widely used in various kinds of human body induction lighting and alarm and so on. | 🚩 The RCWL-0516 microwave radar sensor module can detect inert object at the condition that it has enough density, volume and it is in motion. | 🚩 Microwave radar sensor will sense motion through most anything. The more shielding there is, the less detection range you get. I can detect motion through glass, drywall walls, ceilings and floors. It is very sensitive. You might have to filter the power supply. | 🚩 This microwave detector board can not only detect human but animals and water. | 🚩 Microwave doppler radar sensor can work with arduino/nodemcu/wemos etc.
