![]() Tap the button in the middle and change it to Equals. Tap the pencil icon and select %DISPLAYSTATE. Now where it says Display As, "Activity, Full Display, No Bar". Where it says Name, tap the magnifying glass icon (not the pencil) and tap on your scenes name. Within that task, tap the + again and hit Scene → Show Scene. Tap the gear icon (back) in the top left corner. If this doesn't work for you try the following instead _GLOBAL_BROADCAST. Here you need to enter _GLOBAL_BROADCAST (caps are important). You can ignore everything except where it says Action. Tap on Profiles, and create a new one by using the + button. Tap the gear icon in the upper left corner to go back. Hold down and drag on the dashed line and make it the size of your screen. Repeat "step 11" except that change everything to Display Off and change where we put 1 to 0. Tap %DISPLAYSTATE and where it says To, make it 1. Go to the Profiles tab, and tap + → select Event → Display → Display On. ![]() Tap Preferences → UI (at the top), uncheck Beginner Mode.Įxit out of that, and tap the Vars tab at the top. Launch Tasker app and tap the three dots in the top right corner. Out of two methods that I'm aware of, I've mentioned one below: Method #1. You said that you didn't know how to solder, but there is a very simple way of making your own external sensor for this. Also, you don't have to root your device for this. This will detect motion using the built-in camera, so it's free. I've been using it for a while, and can tell you it will work with other apps in the foreground and with the screen locked. Suggestions welcomed.Īs mentioned by Dallas Partin here, there is a free app called Motion Detector. ![]() Hoping to figure out how to eliminate the LED and just run the PIR directly into the tablet using the headphone jack or USB on the tablet. When I walk by the PIR triggers the LED light allowing the camera to see, which triggers motion. Simple design so far just uses a cheap PIR sensor and a small led light mounted below the camera. I'm currently working on an external PIR motion sensor that will allow the tablet to wake in darkness. Works great during the day or with the lights on. Open the app (or home screen) you want to have displayed on the screen when the tablet wakes, and you're all set! Wait for the screen to go to sleep and walk by or wave at your camera and it will wake it up.Change the sleep settings to time out in the desired time.Open android settings, Turn off the lock screen or select "none".Click on motion detector (at the top) and then scroll down to "camera" and select "front". Open the Motion Detector app and turn on "Send" at the bottom of settings.Then install a plugin called Turn Screen: Just to let you know I have some up with a simple solution it combines an app from the app store called Motion Detector by jastrzab: Not sure how quickly the device would respond to a push when in deep sleep, but that's a secondary problem. I had a quick look regarding waking up the screen in response to push notifications and that doesn't seem too hard using the PowerManager API. The other idea would be the front-facing camera, but the problem seems to be that a) the camera in many devices automatically shuts off when the screen is off and b) only foreground apps can access the camera, but I want the tablet to show another app on detection. But I'm looking for something in the 2-3m area. The problem with using the proximity sensor is that it really only returns whether something (assumed to be your ear while in a call) is right next to it (a few centimeteres away). I investigated a little bit whether this could be done with the existing sensors in the device and I believe that is not possible. The idea here is to transform an old tablet into some kind of stationary dashboard screen, so I'm not particularly worried about battery wear (it's end-of-life now and will from now on be used with the power cable plugged in until it dies) or intense usage (unless we're talking about 100% CPU 24/7, which would probably kill it in a few days). I'm able to write some code from scratch if necessary, but I'm very clueless and unexperienced in the hardware field, so I wouldn't know how to hold a soldering iron, for example. I'm definitely willing to get an external device for this and invest a (reasonable) amount of money, it would just have to be one that I can somehow connect to the tablet.Īre there maybe any proximity detectors from the home automation field with a decent detection quality (good angle and configurable distance) that can send Android push notifications? I'm looking for a motion detector that can be set up to wake a rooted Android (4.3) tablet and turn the screen on when someone passes by it in a radius of maybe 2-3m.
