  • 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...

  • Five tips to make the sensor simpler (1)

    Tip 1 – Start with the bus tool   In the first step, the engineer should take the first time to connect to the sensor by means of a bus tool to limit the unknown. A bus tool connects a personal computer (PC) to the sensor’s I2C, SPI or other protocol that allows the sensor to “t...

    Sensor linearity Typically, the actual static characteristic output of the sensor is a bar curve rather than a straight line. In actual work, in order to make the meter have a uniform scale reading, a fitting straight line is commonly used to represent the actual characteristic curve, and the lin...

    Sensor dynamics The so-called dynamic characteristic refers to the characteristic of the output of the sensor when the input changes. In practice, the dynamic characteristics of a sensor are often expressed in terms of its response to certain standard input signals. This is because the sensorR...

    Static characteristics of the sensor The static characteristics of the sensor are related to the static input signal, the output of the sensor and the input. Since the input and output are independent of time at this time, the relationship between them, that is, the static characteristics of the ...

    Sensor classification At present, there is no unified classification method for sensors, but the following three types are commonly used: 1. According to the physical quantity of the sensor, it can be divided into sensors such as displacement, force, speed, temperature, flow, and gas composition....
