  • Analog Grayscale Sensor V2
    INTRODUCTION The gray-scale sensor is a composition of a photocell (light-controlled variable resistor) and a integrated white LED on board aiming just front of the sensor. With this sensor you can measure ambient light directly from voltage using Analog read pin on your Arduino IDE. It's connected LED will let you compare and provide some reflective feedback to analyse gray scale light ranges. Different colors will apply but only gray scale values will be outputted. This new design includes a much better quality connector that increases life span of the sensor, better voltage range and easy to use.  This is a common sensor for automatic lamps that are turned on when light is not enough. For example, with lack of sun light th..

  • Grove - Digital Light Sensor
    This module is based on the I2C light-to-digital converter TSL2561 to transform light intensity to a digital signal. Different from traditional analog light sensor, as Grove - Light Sensor, this digital module features a selectable light spectrum range due to its dual light sensitive diodes: infrared and full spectrum.    You can switch between three detection modes to take your readings. They are infrared mode, full spectrum and human visible mode. When running under the human visible mode, this sensor will give you readings just close to your eye feelings.   Features Selectable detection modes high resolution 16-Bit digital output at 400 kHz I2C Fast-Mode Wide dynamic range: 0.1 - 40,0..

  • Grove - I2C Color Sensor
    This module is based on the color sensor TCS3414CS with digital output I2C. Based on the 8*2 array of filtered photodiodes and 16-bits analog-to-digital converters, you can gain the color chromaticity of ambient light or the color of objects. Of the 16 photodiodes, 4 have red filters, 4 have green filters, 4 have blue filters and 4 have no filter(clear). With the synchronization input pin, external pulsed light source can provides precise synchronous conversion control.   Features Grove compatible interface 16-Bit digital output with I 2C at 400 kHz SYNC Input Synchronizes Integration Cycle to Modulated Light Sources Operating temperature range -40°C to 85°C Programm..

  • Parallax QTI Light Sensor
    Description • Capable of analog or digital outputs • Unfocused for sensing diffused surfaces • Easily interface with any Parallax microcontroller • RoHS Compliant The Parallax QTI Light Sensor uses a QRD1114 infrared (IR) reflective sensor determine the reflectivity of the surface below it. For instance when the QTI sensor is over a dark surface, the reflectivity is very low and when the QTI is over a light surface, the reflectivity is very high. The QTI Sensors were originally meant to sense the outer rim of a SumoBot® ring; however these little line sensors can be very handy for other applications, including line following and maze navigation. Features: • Capable of analog or digital outputs • No ..

  • UV Sensor
    INTRODUCTION This UV Sensor (Gadgeteer compatible) used GUVA-S12SD chip is suitable for detecting the UV raditation in sunlight. It can be used in UV Index Monitoring, DIY project, UV-A Lamp Monitoring, Plants growing Environmental monitoring...etc.    It can detect the UV wavelength of 200-370nm, fast response, linear analog voltage signal output. Small size, easy for installing. With the diagram of the world health organization UV index grading standards, you can know the UV index from the sensor directly.   This sensor can be powered with 5V or 3.3V which make it compatile with both Gadgeteer, Arduino DUE 3.3V system and standard Arduino UNO / Mega 5V system.  ..
