You can connect and configure an APG Ultrasonic sensor to your Wavelet. Typically, you need to compensate for temperature changes in the sensor. The APG sensor will self-calibrate for temperature changes during each data sample.
For more information about how temperature can affect an APG Ultrasonic Sensor, see Application Challenge: Temperature Gradients in the APG Measurement Expert Blog.

Add a channel to control temperature compensation setting
Add a stream to see the temperature compensation
To add a channel to control the temperature compensation setting:
- Log in to the Ayyeka the UI UI.
- In the left pane, click Devices.
- In the Site Tree pane, select the relevant site, and then select the relevant device that the sensor will be connected to.
- In the right pane, click the Configuration tab.
- In the Configuration window, scroll down and click Advanced Device Configuration.
- In the configuration tree, click Serial to open its folder.
- In the Serial folder, click CHANNEL, and then select the next available channel that does not have a sensor assigned to it. An example might be Serial > CHANNEL > 1.
- In the channel folder, set the following parameters and values:
-
- bus_baud – 9600
- bus_parity – None
- Interface_type – RS-485
- active- AS_ON
- sample_handler – SH_MODBUS_RTU
- wake_time_ms – 13000
- slave_addr- 1
- read_addr- 419
-
- read_type – MODBUS_READ_HOLDING_S16
-
sensor_power_source – Select either PS_EXT3_BOOSTor PS_EXT4_BOOST. If you are unsure, check which setting is used in another Wavelet that is connected to an APG sensor.
-
startup reset flag – 1
- extra_params – 2,1,*
Important: Do not add any space between the values or the commas (,).
To add a stream to see the temperature compensation:
- Swipe the magnetic Wavelet Activator over the Ayyeka symbol on the face of your device.
- In the Ayyeka the UI UI, go to the device with the APG Ultrasonic Sensor.
- Click the Commands Wait about 10-15 minutes after swiping the magnetic Wavelet Activator until the Status column shows all the commands at 100% .
- Click the Configuration tab, and then scroll down to the Stream Management
- Click the Refresh icon . The new APG Ultrasonic sensor stream is listed in the Stream Management table.
- Click the plus sign icon + in the Stream column of the new stream.
a. Set the following parameters in the new stream:
New Stream Display Name: Temperature Compensation
Engineering Units: Unitless ()
b. Click Submit to define the new stream.
7. Click the refresh icon again, and then wait for a transmission to begin receiving values. The Raw Value and the Final Value of the ‘Temperature Compensation’ stream should be 1 (temperature compensation is enabled). A value of 0 means that temperature compensation is disable.
