This Module of Switch Reed uses a Small Device called a Leaf Switch. When the Device is Exposed to a Magnetic Field, the Two Ferrous Materials within the Switch are joined together and the Switch closes. When the Magnetic Field is Removed, the Switch Opens.

The CNY70 has a compact construction where the emitter and receiver are arranged in the same direction to detect the presence of an object using the object's reflective IR beam.

The imported PL2303HX controller can stabilize the flash at high speed. With a 500mA auto-recovery fuse for protection and two data transmission indicators that can monitor the data transfer status in real time. The entire board is coated with a high-quality transparent heat-shrinkable layer, rendering the PCB in a state of isolation from the outside, so that the board is not burned. Electrostatic package, ensures that the plate will not be damaged before use. Supports WIN7 system.

The Rotary Encoders are similar to Potentiometers, however, as they have no physical limits, they can run indefinitely. However, the similarity to a potentiometer is only physical, instead of having a variable resistance, in this type of Encoder we have an impulse output with 20 impulses per turn. In addition to the impulse output, it also has a push button function with two dedicated pins that close when we press the Encoder shaft.

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

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.
