PCF8591 Module Analog to Digital and Digital to Analog Converter Module
The module chip uses PCF8951. The module supports external 4-channel voltage input acquisition (voltage input range 0-5v). The module integrates the photoresistor, which can capture the ambient light intensity with AD. Module integrated thermistor, can collect accurate temperature value of environment through AD.
Module integrates 1 channel 0-5V voltage input acquisition (adjusts input voltage via blue potentiometer). The module has a power indicator (the indicator will light when power is supplied to the module). Module with DA output indicator, when the module DA output interface voltage reaches a certain value, it will light DA output indicator on the board, the greater the voltage, the greater the brightness of the indicator. Module PCB size: 3.6cm*2.3cm. Standard double panel, thickness 1.6mm, beautiful layout, surrounded by holes, aperture: 3mm, easy to fix.
