PCF8591 Module Analog to Digital / Digital-Analog Converter Module

Specifications:

• The module supports external voltage input of the 4-way acquisition (voltage input range of 0-5v)
• The module integrated photoresistor by AD collection precise value of the ambient light intensity
• Module integrated thermistor by the precise value of the ambient temperature of the AD acquisition
• Module integrated 1 channel 0-5V voltage input acquisition (the blue potentiometer to adjust the input voltage)
• Modules with power indicator (for the module power supply indicator lights)
• Modules with DA output indicator, when the module DA output interface voltage reaches a certain value, will be lit panel the DA output indicator, the higher the voltage, the more obvious indicator brightness
• Module PCB size: 3.6cm x 2.3cm
• A standard double panel, thickness 1.6mm, nice layout, surrounded by a through-hole, aperture: 3mm, convenient fixed.
