A / C converter operating principle

Transducers and converters are tools that convert one physical quantity into another. The task of the A / C converter is to convert an analog signal into a digital signal, and thus it is possible to connect digital modules - e.g. Arduino or Raspberry Pi with analog devices and sensors.

Connection of the transducer and description of the leads

The leads are solder pads and screw connectors, allowing for soldering goldpin connectors, 2.54 mm pitch (not included). Thanks to them, it is possible to connect the system with the breadboard or the main module (eg Arduino ) using wires . The board also includes a Qwiic connector, which could be a soldering-free alternative that reduces the number of wires.

  • GND - the ground of the system
  • VCC - power pin
  • SCL - clock line of the I2C bus
  • SDA - data line of the I2C bus
  • ALRT - an alarm signal generated when the analog value exceeds the set threshold
  • A0, A1, A2, A3 - analog inputs
