Product Description

PCF8591 Module AD DA Converter Analog Adapter For Light Temperate Intensity

Description:
PCF8591 is a single-supply, low-power 8 COMS-type A/D, D/A converter chip, it has a 4-channel analog input channels, all the way to the analog output channels and an I2C bus interface. The device I2C slave address lower three chips A0, A1, A2, three address pins devision so without adding any hardware with an I2C bus can connect up to eight devices of the same type. The device has a multi-channel analog input, on-chip track-and-hold, 8 A /D conversion and eight D/A conversion functions.
Definition of the module A / D input and D / A output, 4-channel A / D input module, 1 channel D / A output:
A / D input channel 0: connect external test
A / D input channel 1: one channel potentiometer can test rheostat partial pressure; to connect external test.
A / D input channels: one channel thermistor can measured temperature; connect external test.
A / D input channels: one channel photoresistor can measured light intensity; to connect external test.
D / A output channel 0: 1channel LED highlight show the D / A output voltage value, can produce sine, square wave, triangle wave, a variety of waveforms.
Size: 3cm x 2.3cm - 1.2inch x 0.9inch.
