Description
The Gravio Distance component allows you to retrieve distance measurements from the Gravio Laser Distance sensors.
To use this component you must have paired the Gravio Laser Distance sensor beforehand.
If the Device ID property is empty, the command will be sent to all connected Gravio Distance.
| Output payload | Description |
|---|---|
cv.Payload | Outputs an array of measured distances |
Component properties
| Property name | Description |
|---|---|
| Device ID | Device ID for which the distance is to be measured, if none is set then the distance is measured for all Gravio Distances, if more than one Gravio Distance is used then the device ID can be comma-separated |
Execution errors
| Error code | Error | Description | Countermeasure |
|---|---|---|---|
| ERR--10 | low power | insufficient current | check that the USB cable between the power supply and the sensor is correctly connected |
| ERR--14 | calculation error | execution error | please run again |
| ERR--15 | weak signal | Weak signal | Please do not move the device and remove any obstructions. |
| ERR--16 | unstable laser transition | laser is unstable | hold device and target object still |
| ERR--18 | ambient light too strong | ambient light is too strong | please reduce ambient light |
| ERR--26 | out of display range | please try again |
About the error that occurs when bound to a layer
Note: When a Distance sensor that is bound to a device layer and enabled is specified and used with the Gravio Distance component, the following error will occur:
ERROR 400 action: "GravioLaser": failed to execute: component: GravioDistance: device is being used
This is because the Distance sensor that is bound and enabled in the layer is set to send distance data every 5 seconds, and if the Gravio Distance component is executed when triggered by a trigger, the processes are colliding.
Distance sensors that are bound to a layer and enabled cannot be used in a Gravio Distance component, therefore they should only be used in one of the processes at a time.
