.. _bh1749: BH1749: Ambient Light Sensor IC ############################### .. contents:: :local: :depth: 2 This sample application sets up the BH1749 color sensor to provide 8-bit measurement data every time a set threshold value (>50) is reached for the RED color channel. It also shows how to enable interrupt every time data is ready, instead of threshold trigging. Requirements ************ The sample supports the following device: .. table-from-sample-yaml:: Building and running ******************** This project outputs sensor data to the console. It requires a BH1749 sensor. It should work with any platform featuring a I2C peripheral interface. It does not work on QEMU. The example below uses the Thingy:91. .. |sample path| replace:: :file:`samples/sensor/bh1749` .. include:: /includes/build_and_run.txt Sample output ============= The following output is displayed in the terminal: .. code-block:: console J-Link RTT Viewer device is 0x20022384, name is BH1749 Threshold trigger BH1749 RED: 387 BH1749 GREEN: 753 BH1749 BLUE: 397 BH1749 IR: 81 (continues when trigger level reached) References ********** `BH1749NUC-E`_
