SparkFun Luminosity Sensor - TSL2561

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 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.

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.

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

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

LDR Light Sensor with Relay

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