Carbon monoxide detector with alarm - orno

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.

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 .

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).

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

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.

Finger is a fingerprint sensor that makes fingerprint verification super simple.

The Uart protocol, compact size and ultra low power consumption make the use of MSStack series products very attractive. It performs fast fingerprint matching with the highest level of security and the ideal convenience of the user. You can program to set the level of comparison of the fingerprint recognition and the different security level. If you've ever thought about protecting your project with biometrics, don't forget to include this MSunit Finger.

This unit communicates with the M5Core by UART protocol connected via PORTC.
