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.
- 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

What good is a robot if it can’t interact with the environment around it? Sensors are the backbone of almost every electronics project as they allow your program to make decisions based on external stimuli. We’ve got sensors for all kinds...
- Handheld UV Meter
UV is important to reptiles (and people) in processing vitamin D3 which is needed to absorb calcium. Without it reptiles often suffer from Metabolic Bone Disease (MBD) which leads to weak bones and can be fatal. Thankfully, pet shops have the answer, UV producing globes which can stave off the dreaded MBD. These are in the form of T8 florescent tubes or compact florescent globes and go for $50+ each. And, yeah, they need to be re...
