description:
The PCF8591 is a monolithically built-in, individually powered, low energy, 8-bit CMOS information acquisition gadget. Voltage vary: 2.5V-6V.The PCF8591 has 4 analog inputs, one analog output, and one serial I2C bus interface. The three deal with pins A0, A1 and A2 of the PCF8591 can be utilized for {hardware} deal with programming, permitting entry to eight PCF8591 gadgets on the identical I2C bus with out further {hardware}. The deal with, management, and information indicators enter and output on the PCF8591 gadget are serially transmitted over a two-wire bidirectional I2C bus.
On the left side of the module, you will find the 2-pin connector for various interfaces and chip connections. Here's a breakdown of what you'll see: AOUT chip for digital-to-analog output, AIN0 chip for analog input at interface 0, AIN1 chip for analog input at interface 1, AIN2 chip for analog input at interface 2, and AIN3 chip for analog input at interface 3. This setup allows for efficient circuit connections and voltage readings within the module.
The SCL IIC clock interface is connected to the precise single-chip IO port, while the SDA IIC digital interface is linked to the MCU IO port. Ground the module to the floor and connect the VCC energy interface to an external 3.3v-5v voltage.
This module consists of three pink short-circuit caps, each with a specific interface:
P4 corresponds to P4's short-circuit cap and features an analog thermistor entry circuit.
P5 matches P5's short-circuit cap, offering a photosensitive resistor entry circuit.
P6 aligns with P6's short-circuit cap and provides a 0-5V adjustable voltage entry circuit.
We extremely respect all prospects opinions to enhance the promoting, additionally if something you unhappy, please contact us for possible greatest answer.
Package deal Contains: 3Pcs
The module chip adopts PCF8951 and helps exterior 4-channel voltage enter acquisition (voltage enter vary 0-5v)
Built-in photoresistor, can accumulate correct ambient gentle depth worth via AD, combine thermistor, can accumulate correct ambient temperature worth via AD, combine 1 channel 0-5V voltage enter acquisition (regulate the enter voltage via blue potentiometer)
With energy indicator (lights up after powering the module), with DA output indicator, when the output voltage of the module DA output reaches a sure worth, the DA output indicator on the board will likely be illuminated. The upper the voltage, the extra apparent the brightness of the indicator;
Commonplace double panel, board thickness 1.6mm, stunning structure, via holes round, gap diameter: 3mm, simple to repair
PCB measurement: 3.6cm*2.3cm
