Normally Open SW-18015P Shock Sensor Module Vibration Sensor Alarm Module, 501 Original

Normally Open SW-18015P Shock Sensor Module Vibration Sensor Module Alarm Module BoardFeature:1. Used for various vibration triggering, alarm, intelligent car, electronic building blocks and so on.2. Please note that the triggering time of this module is very short when it senses small vibration, and it is not enough to drive the relay. Some people's data show that it can be directly connected with the relay module, and the actual application effect is not good.3. All kinds of sensitive vibration switches produced by our company are adopted, and SW-18015P vibration sensor is used by default.4. Comparator output, with clean signal, good waveform, strong driving ability, more than 15A.5. Fixed bolt hole for easy installation.6. Using a Wide Voltage LM393 Comparator.Specification:Working voltage 3.3V-5VOutput Form: Digital Switch Output (0 and 1)PCB Size of Small Plate: 32mm*17mm*5mm/1.25*0.66*0.19''Packing weight: 2gModule Interface Description (3-wire):1. VCC external connected to 3.3V-5V voltage (can be directly connected with 5V MCU and 3.3V MCU).2. GND external connected to GND.3. DO board digital output interface (0 and 1).Operation Manual:1. Connect VCC and GND, module power indicator will be on.2. Place the module lightly on the desktop, adjust the blue potentiometer on the board until the switch indicator lights on the board, then slightly adjust the potentiometer, let the switch indicator lights off, and then tap the desktop with your hand to make the vibration sensor have a sense of vibration.3. At this time, the switch indicator lights will be on again. When the vibration stops, the switch indicator will also go out. This phenomenon means that the vibration can trigger the module, so that the switch indicator lights up.Note: Please allow 1-3cm differs due to manual measurement.Due to the different display and different light, the picture may not show the actual color of the item. Thanks for your understanding.1 x Shock Sensor Module
