DFR0031-G Application Field and Working Principle

DFR0031-G is a type of evaluation board manufactured by DFRobot, designed to measure current/voltage, display and store temperature readings and provide data transmission for Arduino boards. It is classified as an expansion board or daughter card since it is connected to an Arduino board and can provide certain functions to the Arduino.

The DFR0031-G board comprises of a bandgap voltage reference circuit, a digital thermistor, a voltage converter and an open drain controller. There are two main components that provide the functions of the board: the Converter and the Open Drain Controller. The Converter takes the input from the Arduino board, converts it to an analog voltage or current that can be read by the board’s sensors. The Open Drain Controller is responsible for controlling the output of the board and communicating with the Arduino board through a serial connection. The board also contains an on-board temperature sensor to measure temperature readings and display them on an LCD display.

The DFR0031-G can be used for various applications such as measuring current/voltage in the range of 0 to 15v, displaying and storing temperature readings, controlling the output of the board and communicating with the Arduino board via an I2C protocol. It can also be used for data logging, prototyping, debugging and testing Arduino applications. The board is also equipped with an on-board RTC which can be used for time-keeping operations.

The main application of the DFR0031-G board is in industrial instrumentation. The board is used for measuring current/voltage readings for various applications such as controlling power, detecting temperature and monitoring system performance. The board can be used in various industrial applications such as process control, factory automation, power management and environmental monitoring. The board is designed to be highly accurate and reliable, making it suitable for use in industrial environments.

The working principle of the board is fairly simple. It takes in an analog voltage or current value from the Arduino board, converts it to a digital form using the converter and then sends it to the Open Drain Controller. The Open Drain Controller then reads the signal and sends it back to the Arduino. The board can also display and store temperature readings from the on-board temperature sensor and transmit it via an I2C protocol to the Arduino board. The board also contains an on-board RTC, which can be used for time keeping operations.

In summary, the DFR0031-G is a highly accurate and reliable evaluation board that can be used for measuring current/voltage, displaying and storing temperature readings and providing data transmit to an Arduino board for various industrial applications. It is classified as an expansion board or daughter card since it is connected to an Arduino board and provides certain functions to the Arduino.
