Converter Module PCF8591

The OKY3475 is a low-power, 8-bit data acquisition module built around the PCF8591 chip. It provides a versatile solution for converting analog signals to digital data for processing by a microcontroller via the I2C interface.

Key Features
- Features four analog inputs for reading signals from various sensors.
- Includes a single analog output (DAC) for generating variable voltage signals.
- Integrated on-board sensors include a photoresistor for ambient light measurement and a thermistor for temperature sensing.
- A built-in potentiometer allows for manual voltage adjustment and testing on one of the analog inputs.
- Communicates via a standard I2C serial interface, with three hardware address pins allowing up to eight modules to be connected to a single bus.

Applications
With its multiple analog inputs and integrated sensors, this module is well-suited for projects requiring environmental monitoring, such as reading data from light and temperature sensors, potentiometers, or other analog devices. The analog output also allows it to control components that require a variable voltage input.
