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

The Gravity: 0-10V 15-Bit High-Precision ADC Module combines dual-channel 0-10V input with I2C and UART interfaces, offering unmatched flexibility for Arduino, Raspberry Pi, and ESP32 users. Featuring 15-bit resolution (0.3125mV accuracy) and the Texas Instruments ADS1115 chip, it bridges industrial 0-10V sensors (e.g., pressure transducers, energy meters) with low-voltage microcontrollers. Perfect for automation, environmental monitoring, and IoT systems requiring stable, noise-resistant signal conversion.

Industrial-Grade 0-10V Sensor Compatibility

The module directly interfaces with industrial-standard 0-10V sensors, such as pressure transducers, flow meters, and wind speed sensors. It resolves the voltage mismatch between high-output sensors (0-10V) and low-voltage microcontrollers (e.g., Arduino, Raspberry Pi), eliminating the need for external signal conditioning.

15-bit Resolution with Enhanced Accuracy

With a 15-bit ADC and ±2mV precision, the module captures subtle signal variations (e.g., 0.3125mV steps), making it suitable for applications requiring fine-grained data, such as water tank pressure monitoring or energy consumption analysis. The ADS1115’s PGA dynamically adjusts gain to maintain accuracy across the full 0-10V range.

Flexible Communication Interfaces

Dual I2C and UART protocols ensure compatibility with diverse controllers, from Arduino boards to industrial PLCs. The Gravity-4P connector standardizes wiring, reducing setup complexity for multi-sensor systems.
