High sensitivity ADS1115 16-bit 4-channel analog-to-digital converter with I2C interface. Easy to use with the programmable gain amplifier (PGA) for adjustable input range and precise readings. 4 channel inputs allow monitoring multiple sensors with a single device. Note: does not include analog GPIO pins. Wide voltage feeding range supports operation from low voltage supplies (designed for 2.0 V and up). Compact form factor for easy integration with microcontrollers and single-board computers (Arduino, Raspberry Pi, ESP32, etc.). Performance: 16-bit resolution provides detailed, accurate data for each channel. Key benefits - Flexible measurement: read up to 4 sensors with one I2C device. - Simple integration: standard I2C communication, compatible with common platforms. - Adjustable input range: PGA enables optimal dynamic range for various sensor types. Use scenarios - Data logging with multiple sensors: temperature, humidity, light, and other analog signals in a single module. - Battery voltage or power monitoring in portable projects and IoT devices. - Prototyping and lab work: precision reads for sensor calibration or electronics experiments.
