WLED/usermods/SN_Photoresistor

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.

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.
