The TSL235R light-to-frequency converter outputs a square wave (50% duty cycle) with frequency directly proportional to light intensity (irradiance). The device has been temperature compensated for the ultraviolet-to-visible light range of 320 nm to 700 nm and responds over the light range of 320 nm to 1050 nm.

The TSL235R can be powered at anywhere between 2.7 and 5.5V, and will typically pull about 2mA of current. It comes in a simple, 3-pin through hole package. No external components are necessary to use the converter, and the digital output allows direct interface to a microcontroller or other logic circuitry.

Features:

  • High-resolution conversion of light intensity to frequency with no external components
  • Communicates directly with a microcontroller
  • Compact three-leaded clear-plastic package
  • Single-supply operation down to 2.7 V
  • Nonlinearity error typically 0.2% at 100kHz
  • Stable 150 ppm/°C temperature coefficient
  • Single-supply operation

Frequency too high
Wednesday, 11 February 2015  |  Julian

Not clear how best to read a frequency as high as 9kHz (from room lighting) with an Arduino. This frequency chokes the attachInterrupt() feature and I would have to put some dark glass over the sensor to put it to use.

TSL235R to the rescue
Wednesday, 30 April 2014  |  Bryan

Was looking for some way to measure sunlight intensity for a solar panel tracking project...and this is ideal, small, cheap, easy to interface to a Arduino and does what it says on the tin!
