# SN_Photoresistor usermod
This usermod will read from an attached photoresistor sensor like the KY-018 sensor.
The luminance is displayed both in the Info section of the web UI as well as published to the `/luminance` MQTT topic if enabled.
## Installation
Copy the example `platformio_override.ini` to the root directory. This file should be placed in the same directory as `platformio.ini`.
### Define Your Options
* `USERMOD_SN_PHOTORESISTOR` - define this to have this user mod included wled00\usermods_list.cpp
* `USERMOD_SN_PHOTORESISTOR_MEASUREMENT_INTERVAL` - the number of milliseconds between measurements, defaults to 60 seconds
* `USERMOD_SN_PHOTORESISTOR_FIRST_MEASUREMENT_AT` - the number of milliseconds after boot to take first measurement, defaults to 20 seconds
* `USERMOD_SN_PHOTORESISTOR_REFERENCE_VOLTAGE` - the voltage supplied to the sensor, defaults to 5v
* `USERMOD_SN_PHOTORESISTOR_ADC_PRECISION` - the ADC precision is the number of distinguishable ADC inputs, defaults to 1024.0 (10 bits)
* `USERMOD_SN_PHOTORESISTOR_RESISTOR_VALUE` - the resistor size, defaults to 10000.0 (10K hms)
* `USERMOD_SN_PHOTORESISTOR_OFFSET_VALUE` - the offset value to report on, defaults to 25
All parameters can be configured at runtime using Usermods settings page.
## Project link
* [QuinLED-Dig-Uno](https://quinled.info/2018/09/15/quinled-dig-uno/) - Project link
### PlatformIO requirements
If you are using `platformio_override.ini`, you should be able to refresh the task list and see your custom task, for example `env:usermod_sn_photoresistor_d1_mini`.
