1. Introduction

Overview

Daviteq AG Tilt Sensor is an Euler angle measurement sensor that utilizes the advanced MEMS acceleration sensor to measure the Euler angles in three directions. The acceleration sensor has high resolution and low noise, allowing it to deliver very high resolution and low-temperature drift.


The AG can be integrated into the wireless transmitter from Daviteq, such as Sub-GHz WS433, LoRaWAN WSLRW, and Sigfox WSSFC, to build the complete Wireless Tilt Sensors.


The AG is also powered by the batteries in the wireless transmitter.

Specification

Sensing technology: MEMS acceleration for X,Y,Z tilt measurement

X/Y/Z tilt angle range: -90.0 to 90.0° for AG-01 X/Y/Z tilt angle range: -90.00 to 90.00° for AG-02 X/Y tilt angle range: -30.00 to 30.00° for AG-03

Resolution: 0.01° for AG-01/ AG-02/ AG-03 and 0.1° for AG-01 (old FW)

Repeatability: ±0.1° for AG-01, ±0.07° for AG-02 and ±0.01° for AG-03


Within ±2.5° of Tilt (for AG-02 version)

  • Max Temperature drift ±0.00065° per ℃

  • Max Non-linearity ±0.0622°

  • Total error in 20℃ deviation ±0.075°

2. Principle of Operation

AG utilizes the three-axis high-accuracy MEMS acceleration sensor to calculate the static Euler angles of the object it is mounted on.


 

The microprocessor of the Wireless transmitter will capture the raw signal of 3-axis acceleration the calculate the tilt angle of X, Y, and Z. Here are the final output values of the device.


X Tilt value

  • 16-bit signed integer

  • X_TILT_VALUE = X_TILT_VALUE_X100 / 100 for AG-01 and AG-02

    X_TILT_VALUE = X_TILT_VALUE_X1000 / 1000 for AG-03

  • Range: -90.00 to 90.00 for AG-01 and AG-02; -30.000 to 30.000 for AG-03

Y Tilt value

  • 16-bit signed integer

  • Y_TILT_VALUE = Y_TILT_VALUE_X100 / 100 for AG-01 and AG-02

    Y_TILT_VALUE = Y_TILT_VALUE_X1000 / 1000 for AG-03

  • Range: -90.00 to 90.00 for AG-01 and AG-02; -30.000 to 30.000 for AG-03

Z Tilt value

  • 16-bit signed integer

  • Z_TILT_VALUE = Z_TILT_VALUE_X100 / 100 for AG-01 and AG-02

    No Z_TILT_VALUE for AG-03

  • Range: -90.00 to 90.00 for AG-01 and AG-02

3. Calibration

The Daviteq AG sensor is factory calibrated. The user may need to perform the zero-ing after installation.


For AG-01 and AG-02 sensor:


To do the Zero-ing, the device must be installed in this direction with max ±5° deviation from Gravity direction.



After fixing the device, please perform the Zero-ing command on the main device (depending on the type of device, which is Sigfox or LoRaWAN or Sub-GHz...).


For AG-03 sensor:


The device is calibrated in 3 positions:

1. X tilt and Y tilt equal 0°

2. X tilt equals +30°

3. Y tilt equals +30°

After fixing the device, please perform the CALIBRATION_TILT_ENABLE command on the main device (depending on the type of device, which is Sigfox or LoRaWAN or Sub-GHz...).

5. Installation Notes

The AG sensor is built-in with the main device. Therefore please refer to the installation procedure for the main device as below:

-Install at zero position X= 0,Y=0, Z=0 of sensor tilt for AG-01, AG-02 and X=0, Y=0 for AG-03

-Max range of AG-03 are -30 to 30 degree
