# 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.
This usermod will read from an attached photoresistor sensor like the KY-018.
The luminance is displayed in both 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
* `USERMOD_SN_PHOTORESISTOR` - Enables this user mod. wled00\usermods_list.cpp
* `USERMOD_SN_PHOTORESISTOR_MEASUREMENT_INTERVAL` - Number of milliseconds between measurements. Defaults to 60000 ms
* `USERMOD_SN_PHOTORESISTOR_FIRST_MEASUREMENT_AT` - Number of milliseconds after boot to take first measurement. Defaults to 20000 ms
* `USERMOD_SN_PHOTORESISTOR_REFERENCE_VOLTAGE` - Voltage supplied to the sensor. Defaults to 5v
* `USERMOD_SN_PHOTORESISTOR_ADC_PRECISION` - ADC precision. Defaults to 10 bits
* `USERMOD_SN_PHOTORESISTOR_RESISTOR_VALUE` - Resistor size, defaults to 10000.0 (10K Ohms)
* `USERMOD_SN_PHOTORESISTOR_OFFSET_VALUE` - Offset value to report on. Defaults to 25

All parameters can be configured at runtime using Usermods settings page.
