BH1745 Colour Sensor

Most suited to detecting the illuminance and colour temperature of ambient light, the BH1745 senses Red, Green and Blue light and converts it to 16bit digital values.

Installing

Full install (recommended):

We've created an easy installation script that will install all pre-requisites and get your BH1745 up and running with minimal efforts. To run it, fire up Terminal which you'll find in Menu -> Accessories -> Terminal on your Raspberry Pi desktop, as illustrated below:

In the new terminal window type the command exactly as it appears below (check for typos) and follow the on-screen instructions:

git clone https://github.com/pimoroni/bh1745-python
cd bh1745-python
./install.sh

Note Libraries will be installed in the "pimoroni" virtual environment, you will need to activate it to run examples:

source ~/.virtualenvs/pimoroni/bin/activate

Development:

If you want to contribute, or like living on the edge of your seat by having the latest code, you can install the development version like so:

git clone https://github.com/pimoroni/bh1745-python
cd bh1745-python
./install.sh --unstable

The install script should do it for you, but in some cases you might have to enable the i2c bus.

On a Raspberry Pi you can do that like so:

sudo raspi-config nonint do_i2c 0
