So how about using a PIR sensor or an RCWL- 0516 sensor with a 5v trigger relay to work an LED and musical movement driven by a motor? Motion detector would set the musical movements and LED off. Sadly my 5v timer relay that I have has a constant 4.70v at its TRIG pin out. WebIt has a sensitivity range of ~7 meters. When triggered its trigger output pin will switch from (LOW) 0V to high (3.3V) for ~ 2 to 3 seconds before returning to its idle LOW state. … WebThe RCWL-0516 is a microwave radar sensor module used for motion detection. The range of the module depends on various factors such as the sensitivity settings, the power supply voltage, and the object being detected. Generally, the range of the RCWL-0516 module is up to 7 meters (23 feet) with a detection angle of 360 degrees. how much is therapy in the uk
