.. _bh1749:
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.
The sample supports the following nRF9160-based device:

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.
The following output is displayed in the terminal:
J-Link RTT Viewer
device is 0x20022384, name is BH1749
Threshold trigger
BH1749 RED: 387
