First, the fault cause of the sensor

There are many reasons for sensor failure, such as circuit failure, mechanical damage,

corrosion and so on. In daily use, excessive wear or improper use of the sensor should

be avoided as much as possible.

Second, the sensor maintenance method

1. Clean the sensor

The sensor needs to be cleaned regularly to ensure its proper operation. First, remove

the sensor and wipe the surface with a clean cloth. Then, use a soft brush or hair dryer

to remove dust and debris from the sensor surface.

2. Replace the cable

If the cable of the sensor is broken or damaged, then a new cable needs to be replaced.

First, cut the damaged cable. The new cable is then connected to the pin of the sensor

via a connector.

3. Calibrate the sensor

In the process of using the sensor, the data of the sensor may be biased due to some

factors. At this point, the sensor needs to be calibrated. The specific steps are to calibrate

according to the instructions provided by the manufacturer, generally by adjusting the

bias and gain of the sensor.

4. Replace the sensor components

If the sensor component is damaged due to prolonged use or accidental impact, it needs

to be replaced with a new component. First, remove the sensor and find the location of

the component. The component is then removed using the appropriate tool and the new

component is installed on the sensor.
