Deskripsi

  • PCF8591 AD/DA Converter Modules
  • Onboard : LDR (light sensor) and Thermistor (temperature sensor)

PCF8591 is a monolithic,single supply, low power,8-bit CMOS data acquisition devices.
PCF8591 has four analog inputs,one analog output and a serial I2C bus interface.
PCF8591 the three address pins A0, A1 and A2can be used for programming the hardware address, allowing access to eight PCF8591 devices on the same I2C-bus without additional hardware.
Input and output on PCF8591device address, control and data signals are by-wire bidirectional I2C bus serially transmitted.

PCF8591 features :
Single power supply
PCF8591 operating voltage range of 2.5V-6V
