PCF8591 Module Analog to Digital / Digital-Analog Converter Module

1. The module supports external voltage input of the 4-way acquisition (voltage input range of 0-5v)
2. The module integrated photoresistor by AD collection precise value of the ambient light intensity
3. Module integrated thermistor by the precise value of the ambient temperature of the AD acquisition
4. Module integrated 1 channel 0-5V voltage input acquisition (the blue potentiometer to adjust the input voltage)
5. Modules with power indicator (for the module power supply indicator lights)
6. 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
7. Module PCB size: 3.6cm x 2.3cm
8. A standard double panel, thickness 1.6mm, nice layout, surrounded by a through-hole, aperture: 3mm, convenient fixed.
