Daviteq AG Tilt Sensor

1. 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.

2. Detail measurement principle and its specification

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_X10 / 10 Range: -90.0 to 90.0
Y Tilt value	16-bit signed integer Y_TILT_VALUE = Y_TILT_VALUE_X10 / 10 Range: -90.0 to 90.0
Z Tilt value	16-bit signed integer Z_TILT_VALUE = Z_TILT_VALUE_X10 / 10 Range: -90.0 to 90.0

5. Installation

The AG sensor is built-in with the wireless transmitter. Therefore please refer to the installation procedure in the manual for the wireless transmitters.

6. Troubleshooting for the AG Tilt Sensor

No.	Phenomena		Reason	Solutions
1	The wireless transmitter is still running and sending data, however, all the measurement parameters are not updated with new values	1.1	The connection between the AG tilt sensor and the wireless transmitter is broken!	Please consult the manufacturer for a warranty or replacement.
		1.2	The battery is almost draining off.	Check the battery status and replace it when necessary.
2	The measured values are not as expected	2.1	The installation direction is not correct.	Please recheck the installation.
		2.2	The sensor is drifting.	Please consult the manufacturer for a warranty or replacement.
3	The reading values are very noisy even though the sensor is in a standstill position.	3.1	The sensor AG tilt sensor got a problem.	Please consult the manufacturer for a warranty or replacement.
4	From system: HW_Error = 1	4.1	The lost connection between the sensor AG sensor and the wireless transmitter	Please consult the manufacturer for a warranty or replacement.
		4.2	The sensor AG sensor got a problem.	Please consult the manufacturer for a warranty or replacement.

7. Maintenance of the AG Tilt Sensor

• There are no moving parts or consumed parts in the AG tilt Sensor. Therefore there is no need to do maintenance.

8. Default configuration

There is no configuration required for the AG tilt sensor. There is only configuration for the Wireless transmitter, please refer to the wireless transmitter's manual.
