ADS1115 16-Bit I2C ADC 4-Channel Programmable Gain Amplifier Module

Description

1. 16-Bit Resolution: The ADS1115 provides high-resolution analog-to-digital conversion, allowing you to measure analog signals with precision and accuracy.
2. 4 Input Channels: This module has four differential or single-ended input channels, which can be used to measure up to four different analog signals simultaneously.
3. Programmable Gain Amplifier (PGA): The PGA allows you to amplify the input signal with selectable gains, which helps you adapt to a wide range of input voltage levels and increase the measurement sensitivity.
4. I2C Interface: The ADS1115 uses the I2C communication protocol (also known as Two-Wire Interface or TWI) for easy interfacing with microcontrollers and other digital devices.
5. Selectable Data Rates: It offers selectable data rates, allowing you to choose the rate at which data is sampled and sent to the microcontroller, which can help balance between speed and power consumption.
6. Low Noise: The ADS1115 is designed for low noise and low power consumption, making it suitable for battery-powered or low-power applications.
7. Built-In Comparator: Some versions of the ADS1115 include a built-in comparator with programmable thresholds, enabling you to trigger actions based on certain signal conditions.
8. Internal Voltage Reference: The module has an internal voltage reference, which can be used as a reference for measurements. Alternatively, you can provide an external reference voltage.
9. Wide Supply Voltage Range: It operates over a wide supply voltage range, typically from 2.0V to 5.5V, making it versatile for various applications.
10. Applications: Common applications for the ADS1115 include data acquisition systems, sensor interfaces, industrial process control, and measurement devices where high-precision analog-to-digital conversion is required.
11. Compact Module: The ADS1115 module is usually compact and easy to integrate into projects.
12. Compatibility: It can be used with a variety of microcontrollers and development boards that support the I2C protocol, such as Arduino, Raspberry Pi, and more.
13. Open-Drain ALERT Pin: Some versions of the module feature an open-drain ALERT pin that can be used to trigger external actions based on measurement conditions, such as exceeding a threshold.
14. Library Support: Many popular microcontroller platforms have libraries and code examples available for the ADS1115, simplifying integration into projects.
