# flipperzero-lightmeter
## Lightmeter app for photography
[Original link](https://github.com/oleksiikutuzov/flipperzero-lightmeter)
An application that suggests settings for your manual camera based on the reading of the ambient light sensor. Can also be used in a pure lux meter mode.
## Supported sensors
<img src="images/framed_gui_main.png" width="500px">
- BH1750
- MAX44009
## Wiring
```
VCC -> 3.3V
GND -> GND
SCL -> C0
SDA -> C1
```
## TODO
- [ ] Save settings to sd card
## References
App inspired by [lightmeter](https://github.com/vpominchuk/lightmeter) project for Arduino by [vpominchuk](https://github.com/vpominchuk).
| Sensor | Flipper Zero |
| ------ | ------------ |
