The inclinometer sensor is a kind of attitude sensor, mainly used in the level detection of the state of the object, and also has the size of the measurement angle. Inclinometer sensors are basically divided into two types. One type can be called a static tilt sensor. Its basic principle is Newton’s second law. This type of sensor is mostly used in the monitoring of static or quasi-static objects. An indispensable measurement tool for industries such as angle detection. It has become an indispensable measurement tool in industries such as dams, bridges, construction, and aerial work platform vehicles.

The other type is the dynamic inclinometer sensor. This type of sensor uses the latest inertial navigation technology to avoid the loss of accuracy during the movement and vibration of the sensor. It can be applied to motion carriers such as drones, smart agriculture, construction machinery, and robots, high-precision measurement of the carrier's posture in motion.

Therefore, when choosing a sensor, you need to choose an inclinometer sensor that suits you according to your own needs. 　　The basic parameters of the tilt sensor: 　　
1, range 　　The range is the maximum range that the sensor can measure, which refers to the difference between the upper and lower limits of the measurement. Each sensor has its own measurement range, and the output signal of the sensor has a certain accuracy when the measurement is within this range. The acceleration sensor within the range of 1G is used as an inclination sensor, use it as an acceleration sensor or a vibration sensor if the range exceeds 1G. Because the larger the range, the smaller the accuracy. The dual-axis inclination sensor can select the range within ±90°, and the single-axis inclination sensor can select 360° in the vertical direction.
2. Accuracy 　　 During the test and measurement process, measurement errors are inevitable. There are two main types of errors: systematic error and random error. The causes of system errors such as inherent errors of measurement principles and algorithms, inaccurate calibration, environmental temperature effects, material defects, etc., can be used to reflect the degree of influence of system errors. Random errors are caused by gaps in transmission parts, aging of electronic components, etc. The degree of influence of random errors can be reflected by precision. Accuracy is a comprehensive indicator that reflects system errors and random errors. The higher the accuracy, the higher the accuracy and precision.

Accuracy is a comprehensive indicator that reflects system errors and random errors. The higher the accuracy, means the higher the accuracy and precision.
3. Zero offset 　　 zero offset means that when the input of the sensor is always zero, the output value of the sensor will still have a small change to a certain extent. There are many reasons for the zero-point drift, such as changes in the characteristics of the sensitive components in the sensor over time, stress release, component aging, charge leakage, environmental temperature changes, and so on. Among them, zero drift caused by changes in ambient temperature is the most common phenomenon.
4. Frequency response  The frequency response characteristic determines the frequency range to be measured, and the undistorted measurement conditions within the frequency range must be allowed. In fact, the response of the sensor always has a certain delay. The higher the frequency response of the sensor, the wider the frequency range of the measurable signal range, and the greater the interference. The lower the frequency response of the sensor, the narrower the frequency range of the measurable signal range and the lower the interference. In practical applications, a large number of measured signals are time-varying signals, such as changes in current value, changes in object displacement, and changes in acceleration. This requires the output of the sensor not only to accurately reflect the size of the measurement, but also to keep up with the speed of the change of the measurement. Within the frequency response range of the sensor, the amplitude of its output has a small change within a certain range (the maximum attenuation is 0.707). Therefore, when the input value changes sinusoidally, it is generally considered that the output value can correctly reflect the input value, but when the frequency of the input value change is higher, the output value will be significantly attenuated, resulting in greater measurement distortion.
5. Hysteresis 　　The hysteresis of the sensor means that when the input quantity changes from small to large or from large to small, the resulting sensor output curve usually does not coincide. That is to say, for the input signal of the same size, when the sensor is in the forward or reverse travel, the output value is not the same, there will be a difference. The main reasons for the hysteresis include the material characteristics and mechanical structure characteristics of the sensor's sensitive components, such as the friction of moving parts, the gap of the transmission mechanism, and the hysteresis of the magnetic sensitive components.

The high-precision digital output inclination sensor independently developed by Woosens provides different measurement ranges for customers to choose.
