SW-420 Motion and Vibration Sensor Module.
This Motion Sensor Module is used to trigger the effect of various vibrations such as burglar alarm, smart car, earthquake alarm, motorcycle alarm and so on.
This module is compared to the vibration sensor module of the normally open type, with a vibration trigger for longer periods of time, which can trigger the relay module.
Features:
• Operating voltage from 3.3V to 5V;
• Output form: Digital switch output (0 and 1);
• Has a fixed screw hole;
• Convenient installation;
• Small board PCB size: 3.2cm x 1.4cm;
• Use the LM393 wide voltage comparator.
Includes:
• 1x SW-420 Motion and Vibration Sensor Module.
DFRobot Relay Shield V2.1 is a completely new design which is capable of controlling 4 relays at a time.
The 5-Channel Infrared Detector Sensor Module is designed to optimize robotics and electronics projects.
SparkFun RGB and Gesture Sensor - APDS-9960
The SparkFun Current Sensor Breakout is a High Precision Card that uses the ACS723 for Moderate AC and DC Current Detection Applications. The ACS723 Sensor uses a Hall Effect Sensor to Emit a Voltage relative to the Current that flows through the IP + and IP- Pins on the Board. The advantage of using a Hall Effect Sensor, specifically, is that the Circuit Being Detected and the Sensor Reading Circuit are Electrically Isolated, which means that although your Arduino is Operating at 5V, the Detected Circuit may be Operating at Higher DC or AC voltages.
