  • Anti-jamming technology 7 in sensor monitoring

    7, multi-point grounding   Multi-point grounding is generally recommended for high frequency circuits. At high frequencies, even a small piece of ground wire will have a large impedance drop, and with the effect of distributed capacitance, it is impossible to achieve a little grounding. Therefore...

  • Anti-jamming technology 6 in sensor monitoring

    6, a little ground   A low-level circuit is generally recommended for low-frequency circuits. It has a radial ground wire and a bus-type ground line. Radial grounding is the direct connection of each functional circuit in the circuit with the zero potential reference point: the bus-type grounding...

  • Anti-jamming technology 4 in sensor monitoring

    4, low frequency magnetic shielding   If the interference is a low-frequency magnetic field, the eddy current phenomenon is not obvious at this time. The anti-interference effect is not so good only by the above method. Therefore, it is necessary to use a high magnetic permeability material as a ...

  • Anti-jamming technology 2 in sensor monitoring

    Anti-jamming technology 2 in sensor monitoring 2, electrostatic shielding   According to the principle of electromagnetics, there is no electric field line inside the sealed hollow conductor placed in the electrostatic field, and the internal points are equipotential. Using this principle, a meta...

  • Anti-jamming technology in sensor monitoring

    Anti-jamming technology in sensor monitoring Since there are often a large number of electrical and magnetic interference sources at the production site, they can damage the normal operation of sensors, computers and even the entire inspection system. Therefore, anti-jamming technology is an impo...

  • Five tips to make the sensor simpler (5)

    Tip 5 – Use a sensor fusion library   The chance is that the sensor’s transmission interface is not too new, and no one has done this before. All known libraries, such as the “sensor fusion library” provided by many chip manufacturers, help developers quickly master, and e...

  • Five tips to make the sensor simpler (4)

    Tip 4 – Using Sensor Vendor Code   Any sample code that can be “searched” from the sensor manufacturer, engineers need to go a long way to understand how the sensor works. Unfortunately, many sensor vendors are not experts in embedded software design, so don’t expect to fi...

  • Five tips to make the sensor simpler (3)

    Tip 3 – Test the sensor with Micro Python   One of the advantages of writing the first piece of application code in Python is that by calling Micro Python, the application calls to the bus tool application programming interface for easy replacement. Micro Python runs in real-time embedded s...

  • Five tips to make the sensor simpler (2)

    Tip 2 – Write the transport interface code in Python   Once the developer has tried to use the sensor of the bus tool, the next step is to write the application code for the sensor. Instead of jumping directly to the microcontroller’s code, write the application code in Python. Many b...
