This module (HCMODU0098) is a breakout board for the Texas Instruments ADS1115 ADC. This device provides a precision 16 bit analogue to digital (ADC) resolution. Designed with precision, low power and ease of implementation in mind. The ADS1115 features onboard reference and an oscillator. A serial I2C interface allows interfacing to the module with only two pins and it's slave address can be configured on one of four addresses, allowing for multiple modules to be connected to one I2C bus. The ADS1115 can perform conversions at rates up to 860 samples per second (SPS). An onboard PGA is available that offers input ranges from the supply to as low as ±256mV, allowing both large and small signals to be measured with high resolution. The ADS1115 also features an input multiplexer (MUX) that provides two differential or four single-ended inputs.

The ADS1113/4/5 operates either in continuous conversion mode or a single-shot mode that automatically powers down after a conversion and greatly reduces current consumption during idle periods.

Raspberry Pi users:

For Raspberry Pi uses we have tested this module with the free Cayenne cloud based IoT software platform. Simply connect the module to your Raspberry Pi as shown below and use the Cayenne software platform to get remote analogue voltage readings without writing a single line of code.

Arduino users:

To make using this module with your Arduino as easy as possible we have written an exclusive library (HCADS111x). This library can be downloaded from the software section of our support forum here:

viewtopic.php?f=58&t=2025

The library will allow you to obtain readings out of the 4 analogue input pins (A0-A3).
