Description
Product Overview
- Analog-to-digital converter (ADC) with I2C interface for 3.3 V systems
- Converts analog input voltages into digital values
- 16-bit resolution
- Four independent measurement inputs
- Direct connection to single-board computers such as the Raspberry Pi without a level shifter
Product Description
The analog-to-digital converter adds the ability to process analog voltage signals to single-board computers. While the Raspberry Pi and similar systems only have digital inputs, this I2C-based converter enables the acquisition of sensor signals, voltage levels, or other analog measurement values, which can then be evaluated by the computer.
The module uses I2C for communication, so only two lines (data signal and clock) are required for connection. The 16-bit resolution enables precise measurements across the entire input voltage range from 0 to 3.3 V. Up to four analog sources can be connected simultaneously, saving space and simplifying wiring.
Typical applications include capturing light sensor values for brightness detection, measuring potentiometer or humidity sensor outputs, and monitoring battery voltages. Audio level values or rapidly changing measurement signals can also be evaluated. Multiple modules can be operated on one bus using different I2C addresses to increase the number of measurement inputs.
The 3.3 V operating voltage corresponds to the standard used by the Raspberry Pi and other modern single-board computers, so a level shifter is not required. An I2C library and example code for the target platform should be available. The ADC requires a stable power supply; interference in the power supply will reduce measurement accuracy.
Safety Notice
Input voltages above 3.3 V will damage the module. Measurement signals must be within the permitted range or adjusted using external voltage dividers. The device is intended exclusively for building prototypes and for testing and development purposes, and is not suitable for installation in household electrical systems. If you have questions about integration into existing systems, consult a qualified electrician.
