Light Spectrum Sensor Arduino

Here s what you need.

Light spectrum sensor arduino.

This module is based on the i2c light to digital converter tsl2561 to transform light intensity to a digital signal. A buzzer is connected to pin 11 of arduino. A light sensor measures the radiant energy present in the wide range of frequencies in the light spectrum. Infrared and full spectrum.

It is most suited for arduino open source development boards. 439 the tsl2561 luminosity sensor is an advanced digital light sensor ideal for use in a wide range of light situations. If bias increases than 3 3v it may hurt the sensor. The data is output in a csv compatible form for capture in either a terminal program to import into excel or simply cut and pasted directly into excel from the arduino serial monitor screen.

The device is sensitive in the 200 370 nm range which cover most of the uva and uvb spectrum. Otherwise you can interface with any controllers having i2c lines. Sens 43uv analog ultraviolet light sensor module. So you finally get a spectrum with 128 3 384 pixels.

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. With the 10kohm potentiometer you can change the integration time between 0 and 256 ms. It produces an analog output proportional to the amount of uv light it receives. Arduino light sensor.

The intensities of the pixels within the sensor values are interpolated with a straight line linear interpolation. The analog input pin converts the voltage between 0v and vcc into integer values between 0 and 1023 called adc value or analog value. The arduino sketch is also similarly simple. How to use a light sensor with arduino.

Arduino s pin a0 to a5 can work as the analog input. Grove digital light sensor. By connecting a pin of the photoresistor to an analog input pin we can read the analog value from the pin and then we can know the light levels relatively. Compared to low cost cds cells this sensor is more precise allowing for exact lux calculations and can be configured for different gain timing.

Adafruit industries unique fun diy electronics and kits adafruit tsl2561 digital luminosity lux light sensor breakout id. The sens 43uv analog ultraviolet light sensor module is typical of uv sensor modules. Working of arduino light sensor. With this range you can also examine very dark light sources.

Rgb light sensor isl29125 breakout board. We ve gone through the theoretical side of light sensors and now its time for our light sensor arduino tutorial. An array stores all the needed pwm values to deliver the range of visible light from red to blue.
