LightHz Click Board
IC/Module: TSL230BR Programmable Light-To-Frequency Converter
TSL230BR is a light-to-frequency converter that combines a configurable silicon photodiode and a current-to-frequency converter. The output can be either a pulse train or a square wave with frequency directly proportional to light intensity. It has programmable sensitivity and full-scale output frequency.
According to the sensor specification, the frequency scaling and sensitivity selection of the LightHz click can be set by bringing the logic combination to S0-S3 lines. This can be done by soldering corresponding SMD jumpers to appropriate logic voltage levels, or they can be connected to the microcontroller and determined by software. The board comes with SMD jumpers which are set to ON-BRD configuration of scaling and sensitivity. If the user want S0-S3 lines to be available to the microcontroller, just resolder the SMD jumpers to the MCU position. Default onboard configuration for scaling is (S2, S3) = (H, H), which represents a value of 100, and for sensitivity is (S0, S1) = (H, H), which represents 100x.
