The threshold can adjust using an on-board potentiometer. Specification Operating voltage 3.3V ~ 5V Output format digital switching output (0 and 1) Dimensions (mm) 40x15x7 Operating Current 15mA Country of Origin…
This SW-520D Vibration Sensor Metal Ball Tilt Switch is sealed in shrink tubing. Two conductive elements are located on one end of the sensor (poles). When the sensor is oriented, so the leads are facing down, the mass rolls onto the poles and shorts them, acting as a throw switch. Roller ball tilt switches can…

The TCS3200 Color Recognition Sensor Module uses a high-quality light sensor that allows us to detect any colour by combining Red, Green, and Blue signals. White light is made up of three primary colours with distinct wavelengths (red, green, and blue). These colours blend together to create various shades of colour. Depending on the qualities…
This is Vibration/Shock sensor module can be used for various vibration trigger functions, including reported theft alarms, smart cars, electronic building blocks, and more. Please be aware that normally open vibration sensor modules may induce a very slight vibration when the trigger time is very brief, which is insufficient to operate the relay and renders…
