Electrolytic Condenser for use in rectifier circuits, power supplies and general electronic circuits. When connecting the Electrolytic Condenser, check the polarity of the terminals to prevent component damage. The larger terminal corresponds to the positive, and the smallest to the negative.

Ficha Jack 3.5mm 4P Macho

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.

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

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

LDR Light Sensor with Relay

Energy Saving Lamp E27 15W 230V Green - EDM.

LDR (or light-dependent resistance , or photoresistor ) is a variable resistance. The light falling on the sensor decreases the resistance .

The flame sensor can be used to detect fire or another wavelength in light from 760 nm - 1100 nm.

SparkFun Luminosity Sensor - TSL2561

Basic breakout board for the TEMT6000 Ambient Light Sensor.

This is a simple to use Light Sensor that outputs an analog value from 0 to 5V.

Light Sensitivity Switch Kit, Velleman.

The MAX30100 is a complete solution of Pulse Oximetry System and Heart Rate Sensor. The MAX30100 provides a very small solution without sacrificing optical or electrical performance.

The Grove – UV Sensor is used for detecting the intensity of incident ultraviolet(UV) radiation. This form of electromagnetic radiation has shorter wavelengths than visible radiation. It is based on the sensor GUVA-S12D.It has a wide spectral range of 200nm-400nm. The module will output electrical signal which is varied with the change of the UV intensity. UV sensors are used for determining exposure to ultraviolet radiation in laboratory or environmental settings.

This LED Matrix 24 × 8 display is specially designed for the FireBeetle series. It supports low power mode and scroll display. With HT1632C high-performance LED driver chip , each led has an independent register, which facilitates separate driving. Integrates a 256KHz RC clock, only 5uA in low power mode, supports 16-scale PWM brightness adjustment. This product also works with another Arduino microcontroller like Arduino UNO (same as DFRduino UNO).
