Gravity: 0-10V 15-Bit Dual-Channel High-Precision ADC Module for Arduino / Raspberry Pi / ESP32

The Gravity 0-10V 15-Bit Dual-Channel ADC Module enables 3.3V and 5V microcontrollers to read industrial-grade 0 to 10V analogue signals with high precision. Powered by the Texas Instruments ADS1115 chip, it is designed for students, makers, and engineers working on IoT, automation, and data-logging projects with Arduino, Raspberry Pi, or ESP32 boards.

High-resolution 15-bit signal conversion

Featuring the Texas Instruments ADS1115 converter, the module delivers 15-bit resolution with 0.3125mV steps and ±2mV precision. A built-in programmable gain amplifier dynamically adjusts gain to preserve measurement accuracy across the full 0-10V input range.

Direct industrial sensor compatibility

The dual-channel design connects directly to standard 0-10V industrial sensors such as pressure transducers, flow meters, and wind speed gauges. It safely bridges high-voltage sensor outputs with low-voltage microcontrollers without requiring extra signal conditioning circuits.

Flexible I2C and UART interfaces

Dual communication support over I2C and UART ensures wide compatibility with microcontrollers, single-board computers, and industrial PLCs. The included Gravity-4P connector standardises wiring to simplify prototyping and multi-sensor setups.

Versatile industrial and environmental applications

This converter is suited to tracking pipeline pressure and temperature in automation setups, capturing environmental sensor data, and monitoring analogue signals from solar inverters or energy meters.

Package contents

The kit includes one Gravity 0-10V 15-bit dual-channel ADC module and one Gravity-4P I2C/UART connection cable.
