Level Control and Delivery Systems Using Compensated Silicon Pressure Sensors and Precision Delta-Sigma ADCs, Part 2

This reference design describes a cost-effective, low-power liquid-level measurement data acquisition system (DAS) that use a compensated silicon pressure sensor and a high-precision delta-sigma ADC. The document explains how to implement a design that measures and distributes most industrial liquids using a noncontact measurement approach. It also suggests system algorithms, provides noise analysis, and describes calibration ideas to improve system performance while reducing complexity and cost.

remote text graphic display

This design uses GD32F350 as the main control, OLED12864 as the display screen, and the ESP8266 module as the display of the network connection module. After the system starts, it will automatically connect to the server (using server software written in Yi Language). You can then use the B2 button to obtain network time updates to the microcontroller system and calibrate the current time. In the receiving mode, pictures and text information from the server can be received. The microcontroller processes the transmitted information and displays it on the OLED screen. The design can be used as a task server, sending tasks from the network and then displaying them using OLED for easy viewing. It can be used as an electronic note and placed at home or at work to remind yourself of the work that should be completed today. The design also includes an alarm clock. Users can set an alarm clock to remind themselves, which can be used to wake up, task reminder, etc.

Motor current detection system solution based on ADSP-CM408 and AD7403

For small and medium power motor applications, the EPSH-MPC development platform provides current sampling of the isolated analog-to-digital converter AD7403. The external current loop is converted into a corresponding shunt voltage through a shunt resistor and input to the voltage test terminal of the AD7403. The AD7403 outputs according to the clock signal given by CM408F. ADC bit stream, CM408F enables the built-in SINC filter on the input bit stream to calculate the corresponding 16-bit ADC value, and stores the data into the corresponding ring queue through DMA. The host computer software can use the UART-USB port Or obtain the display of data samples through the RS485 port, you can intuitively see the acquisition effect of AD7403, and the collected data can be stored in an excel table to facilitate corresponding analysis of the data.
