Este módulo usa um interruptor de inclinação de mercúrio para ativar um LED. Há também uma saída digital conectada através de uma resistência de 10K embutido.

SW-420 Motion and Vibration Sensor Module.

This semiconductor gas sensor detects the presence of combustible gas and smoke at concentrations from 300 to 10,000 ppm. The sensor’s simple analog voltage interface requires only one analog input pin from your microcontroller.

This Flame Sensor is sensitive to the flame, but also can detect ordinary light. Usually used as a flame alarm. 

This is the Magnetic Door Switch Set, a small reed switch assembly specifically designed to alert you when doors, drawers, or any other aperture opens.

ITEAD's light sensor is mainly used to detect the intensity of light in the environment.

The KY039 Infrared Pulsation Sensor is a small, inexpensive plate used to measure the electrical activity of the heart to enable heart rate / pulse checking in different parts of the human body. The data presented by the Sensor is useful for formulating exercise routines or even for studying and verifying heart activity levels.
