PCF8591 AD / DA / Analog to Digital / Digital-to-Analog Converter Module w/ Dupont Cable - Deep Blue
Adopts PCF8951 chip Supports external 4-way voltage input acquisition (voltage input range is 0 to 5 v) Integrated photosensitive resistance£¬ can pass AD gathering accurate numerical value of environmental light Integrated thermal resistor£¬ can pass AD collection environment temperature precise values Integrated 0 to 5V voltage input acquisition (by blue potentiometer to adjust the input voltage) After With power indicator light (for the module power supply indicator goes on) With DA output module£¬ when the module DA output voltage reaches a certain value£¬ DA output indicator light will light up board£¬ the bigger the voltage£¬ the brighter the indicator
