Gravity 2-Channel 15Bit 0-10V ADC Module

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

Features:

• The module supports two independent 0-10 V channels.
• The integrated ADS1115 chip offers 15-bit resolution.
• The measurement deviation is less than ±2 mV.
• The I2C and UART interfaces are available simultaneously.
• The power supply is 3.3-5 V.
• The I2C address is by default 0x48 (configurable).

Applications:

• Acquisition of pressure or fill 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 prototyping and industrial projects with precise analog measurement.
