PCF8591 ADC DAC Module

PCF8591 ADC and DAC Module

IIC 4 Channel Analog Input 1 Channel Dac Output AD DA Signal Converter Ldr Light Ntc Temperature Pot 0-5V Voltage Measurement

     It is an analog digital signal detection sensor board using the Nxp PCF8591 integrated circuit. Board connection is established with IIC communication. There are 4 channels of analog signal input. There is 1 channel of dac output. You can measure different analog signals by using the external inputs. Digital data can be converted to analog signal with the IIC connection. There is a led connected on the board to this dac output. The dac output can be observed visually by monitoring the led light brightness. It is quite suitable for applications of generating and detecting analog and digital signals.

     There are Ldr, Ntc and 0-5V pot on the board. These 3 hardware components can be connected to the analog inputs with jumpers. Light measurement can be made with the Ldr. Day night light darkness detection is made with this sensor.  Ambient temperature can be measured with the Ntc sensor. 0-5V voltage variation can be detected with the pot.  There is a 4 pin male header connection socket for IIC and power. Analog inputs and outputs are made over the 5 pin male header.
