ANALOG TO DIGITAL MODULE PCF8591

IN STOCK Quantity

Module supports four external voltage input capture (voltage input range 0V ~ 5V)
Module integration photoresistor can collect ambient light intensity by AD exact value
Module integrated thermistor, the ambient temperature can be collected by exact numerical AD
Module integrates one road 0V ~ 5V voltage input capture (via the blue potentiometer to adjust the input voltage)
Modules with power indicator (for the module power indicator lights)
Modules with DA output indicator, when the module DA output interface voltage reaches a certain value, the DA output indicator will light, the greater the voltage, the brighter the indicator
