# parkingSensor

**What is the parkingSensor used for?**
The parkingSensor is used to make parking easier or to check whether a parking space is occupied. This data is relayed to the user via 4 outputs to which, for example, an RGB/RGBW LED strip can be connected to indicate, by colour, the distance of the car from the virtual wall.

**How is the distance indicated?**
The indication takes place in four stages by controlling three outputs and signalling whether a space is occupied via one output:
Output R flashes and the others are switched off within a range of 0–4 cm from the artificial wall.
It switches on output R and switches off the others within a range of 4–17 cm from the artificial wall.
It switches on output B and switches off the others within a range of 17–48 cm from the artificial wall.
It activates output G and deactivates the others within a range of 48–140 cm from the artificial wall.

**What is a virtual wall? How do you set it up?**
A virtual wall is a configurable plane in space from which the parkingSensor measures distance. A description of the configuration is provided in [**the parkingSensor manual**](https://blebox.eu/en/manuals/).

**How do you power the parking sensor?**
From the same power supply as the LED strip. Supply voltage: 7–24 V DC.

**Does the parking sensor have Wi-Fi? Can its status be read or transmitted via Wi-Fi?**
The parkingSensor does not have Wi-Fi. Transmitting its status via Wi-Fi is possible using a Wi-Fi controller and actions, e.g. the inputSensor D or Q controller, or the switchBoxDC.
By connecting the parkingSensor’s output to the controller’s push-button input and configuring [**actions,**](https://blebox.eu/faq/faq_all/#all_WiFi) you can control other devices via a static IP address on the local network, based on whether a parking space is occupied. **[The extended manual](https://blebox.eu/instrukcje),**which can be found on the **[blebox.eu](https://blebox.eu/)** website or **[at this address](https://blebox.eu/instrukcje),** will be useful for this**.**For advanced users, we recommend **[the API technical documentation.](http://technical.blebox.eu/)**
