What is everyone using for light sensors?

1

I am working on some light automations that are based on motion and amount of light in a room. I am looking for any recommendations on light sensors that can collect lux data that I can use for a trigger.

Thanks in advance!

I use a Xiaomi Mijia Smart Light Sensor via Zigbee2MQTT:

Been working great for around 4 months now and still shows 100% battery (if that is correct). Reports very often, as you can see below, although a dull day today. I have it in a window and use it to automate my downstairs lighting to only turn on when dark.
