[F/BETA] PressureSensor - Detect Current Pressure

gordonlu310 · May 9, 2022, 10:46am

Introduction

A non-visible extension that measures the ambient air pressure in units of hPa or mbar. Not all devices have a pressure sensor. To check whether a device does, use the Available block in this extension.

This works exactly like it should in AppyBuilder, and should also be like Kodular, because I modified the source code from AppyBuilder in GitHub to here. Thank you @Hossein!

This extension is currently under beta testing and may not work.

Release date: 2022-05-09T07:00:00Z

Package name: com.gordonlu.pressuresensor

Version: 1

Built with: Niotron IDE

Documentation

Event blocks

PressureChanged

This event is fired when the pressure detected has changed.

Parameters: pressure = number (float), altitude = number (float)

Property blocks

Altitude (read, blocks)

Returns the current altitude of the pressure sensor.

Requires: number (float)

Available (read, blocks)

Checks whether the pressure sensor is available on this device.

Requires: boolean

Distance (read, blocks)

Returns the distance of the pressure sensor. I am still figuring out the unit for this block.

Returns: number (float)

Enabled (read, write, designer, blocks)

Checks whether the sensor should be enabled.

Requires: boolean

KeepRunningWhenOnPause (read, write, designer, blocks)

Checks whether the sensor is keep running even when paused.

Requires: boolean

MaximumRange (read, blocks)

Requires: number (float)

Pressure (read, blocks)

Returns the pressure of the pressure sensor.

Requires: number (float)

If I blow into the charging port, could it detect that?

I'm thinking kazoo here.

It depends if your phone has a pressure sensor.
