I2C ADS1115 16 Bit ADC 4 channel Module

The ADS1115 ADC Module is a high-resolution 16-bit analog-to-digital converter designed for accurate signal measurement in embedded and industrial applications. The module communicates through the I2C interface, allowing easy integration with microcontrollers such as Arduino, ESP32, Raspberry Pi, STM32, and other development platforms.

The ADS1115 supports four single-ended analog inputs or two differential input channels, making it suitable for measuring sensors, voltages, and low-level analog signals with excellent precision.

The module includes an internal programmable gain amplifier (PGA) that allows users to select different voltage ranges for improved measurement accuracy. It also features a programmable data rate from 8 samples per second (SPS) up to 860 SPS, providing flexibility between speed and precision.

With its low power consumption and built-in comparator, the ADS1115 is ideal for portable devices, automation systems, battery monitoring, and sensor-based applications.
