3pcs PCF8591 AD/DA Analog-Digital-Analog Converter Module Measure Light and Temperature Produce Various Waveforms

Feature:

This board adopts the new AD/DA chip PCF8591, which has reasonable design and stable performance.

This module A/D input and D/A output are defined. 

The module has 4 A/D inputs and 1 D/A output:

1. A/D input channel 0: connect external test;

2. A/D input channel 1: one potentiometer can measure the varistor partial pressure; connect external test;

3. A/D input channel 2: One-way thermistor can measure temperature; connect external test;

4. A/D input channel 3: One-way photoresistor can measure light intensity; connect external test;

5. D/A output channel 0: One LED displays the D/A output voltage value through brightness, which can generate various waveforms such as sine wave, square wave and triangle wave.

Package includes:
