Maxbell PCF8591 Multifunction AD/DA Conversion of Analog to Digital/Digital-to-Analog Module Converter Temperature Illumination

Description:

Single Power Supply, low standby current, 8-bit CMOS data acquisition devices..

PCF8591 has 4 analog inputs, one analog output and a serial I2C bus interface.

Operating voltage range: 2.5V-6V, analog voltage range from VSS to VDD.

Control and data signals are through the two-wire bi-directional I2C bus to serial transfrom.

Allowing access to eight PCF8591 devices on the same I2C bus without additional hardware.

Specification:

Material: Module

Size: Approx. 36x23x9mm / 1.42x0.91x0.35inch

Package Includes:

1 Piece PCF8591 AD/DA Converter Module

Note:

A module chip PCF8951

2 module supports four external voltage input acquisition (voltage input range 0-5v)

3 modules integrated photoresistor, you can collect the ambient light intensity AD exact numeric

4 modules integrated thermistor, you can collect the ambient temperature exact numeric AD

5 module integrates a road 0-5V voltage input acquisition (via the blue potentiometer to adjust the input voltage)

6 modules with power indicator (on the module power indicator will light)

7 modules with DA output indicator, when the module DA output interface voltage reaches a certain value, it will light up the board DA output indicator, the greater the voltage, the LED brightness is more obvious;

8 standard dual panel, thickness 1.6mm, nice layout, surrounded by a through-hole, pore size: 3mm, convenient fixed
