# ADS1115 16-Bit ADC with four inputs
|
||||
|
||||
This usermod will read from an ADS1115 ADC. The voltages are displayed in the Info section of the web UI.
|
||||
|
||||
Configuration is all completed via the Usermod menu. There are no settings to set in code!
|
||||
|
||||
## Installation
|
||||
|
||||
Add the build flag `-D USERMOD_ADS1115` to your platformio environment.
|
||||
Uncomment libraries with comment `#For ADS1115 sensor uncomment following`
