PCF8591 Module AD/DA Analog-Digital Converter Module

 PCF8591 Module AD/DA Analog-Digital Converter Module

This is an PCF8591 Module AD/DA Analog-Digital Converter Module. The PCF8591 is a 8-bit CMOS data acquisition device. The PCF8591 has the four analog inputs, one analog output and a serial I2C bus interface. PCF8591 has three address pins A0, A1 and A2 that can be used to set the I2C hardware address, 8 PCF8591 could be on the same I2C bus, without the need for additional hardware. On the PCF8591 control and data signals are transmitted in serial fashion via the two-wire bidirectional I2C bus.

Technical Datasheet

Module Features

• 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
