Description
Description:Main Performance Indicators of PCF8591:
Single power supply
Operating voltage range of PCF8591 is 2.5V-6V
Low standby current
_Serial Input/Output Through I2C Bus
PCF8591 addressing through three hardware address pins
The sampling rate of PCF8591 is determined by the I2C bus rate.
Four analog inputs can be programmed as single-ended or differential inputs
Automatic Incremental Channel Selection
The analog voltage range of PCF8591 is from VSS to VDD.
PCF8591 Built-in Tracking and Holding Circuit
8-bit successive approximation A/D converter
Achieving DAC Gain by One Analog Output
Two Baby Descriptions
1 module chip adopts PCF8951
2 modules support external 4-way voltage input acquisition (voltage input range 0-5v)
3 module integrated photoresistor, which can collect precise values of ambient light intensity by AD
4-module integrated thermistor, which can collect precise values of ambient temperature by AD
Five modules integrate a 0-5V voltage input acquisition circuit (adjust the input voltage by blue potentiometer)
Module 6 with power indicator (the indicator will be on after power supply to the module)
When the output interface voltage of DA reaches a certain value, the DA output indicator lamp will be lit on the board. The higher the voltage, the more obvious the brightness of the indicator lamp.
8 Module PCB Size: 3.6cm*2.3cm
9 standard double panels, 1.6 mm thick, beautiful layout, with through holes around, aperture is: 3mm, easy to fix
Three-module Interface Description
The left and right sides of this module are expanded with 2-way needle arrangement interfaces respectively, which are explained as follows:
DA output interface of left AOUT chip
AINO chip analog input interface 0
AIN1 chip analog input interface 1
AIN2 chip analog input interface 2
AIN3 chip analog input interface 3
SCL IIC clock interface on the right is connected with IO port of SCM
SDA IIC Digital Interface Connected with IO Port of Single Chip Microcomputer
Out-of-Ground Grounding of GND Module
VCC power interface external 3.3v-5v
Instructions for Use of Four-Module Red Short-Circuit Cap
There are three red short-circuit caps in the module, which are used as follows:
P4 is connected to P4 short-circuit cap, and the thermistor is selected to connect to the circuit.
P5 is connected with P5 short-circuit cap and opt for photoresistor access circuit
P6 is connected with P6 short-circuit cap and 0-5V adjustable voltage is selected to access the circuit.
