DFRobot Gravity 2-Channel 15Bit 0-10V ADC Modul

The DFRobot Gravity ADC Module DFR1184 enables precise measurement of 0–10 V analog signals across two channels. It utilizes the ADS1115 chip and offers a resolution of 15 bits with an accuracy of better than ±2 mV. The sensor outputs signals directly via I2C or UART, making it versatile for use with microcontrollers such as Arduino, ESP32, or Raspberry Pi. A switch on the board allows for easy toggling between I2C and UART modes. Thanks to its robust design and flexible communication options, the module is ideal for industrial applications, environmental monitoring, or automation projects that require high-quality 0–10 V sensor signals.

Features:
The module supports two independent 0–10 V channels. The integrated ADS1115 chip provides 15-bit resolution. The measurement deviation is under ±2 mV. The I2C and UART interfaces are available in parallel. The power supply ranges from 3.3 to 5 V. The default I2C address is 0x48 (configurable).

Application Examples:
Measurement of pressure or level values in automation systems. Monitoring of 0–10 V sensor signals in environmental measurement technology. Integration into smart home systems to expand analog inputs. Use in prototype development and industrial projects requiring precise analog measurement.
