I had to pass my hand very close to the sensor for it to work (20 centimeters). In no way does it reach the 6 meters mentioned in the description! It also has the following peculiarity: when it detects movement, it turns on a lamp. If it detects movement again, then it turns off the lamp. As you can understand, this function is useless. Especially if it is used with an LED lamp that has limitations in its on and off cycles, then you understand that such a sensor is unsuitable, as it will quickly burn out the lamp. I cannot understand the logic of those who made it. It probably functions more as a light show
