Update: This story is from our legacy Android app. Today, we recommend that you, your teams, and your organization deploy dedicated Industrial IoT sensor hubs for monitoring. Sensor hubs are more reliable, cost-effective, power-efficient, and overall superior to telephones for monitoring Industrial IoT sensor devices for things like flood warning systems, Smart Water, wells, tanks, and other applications you’ll see on our Industrial IoT Customer Success Stories page.
Please don’t hesitate to get in touch with me at Info@Valarm.net if you’ve got any questions.
Here’s what you’ll need for affordable remote monitoring of your windows in your home, office, or anywhere else:
- Valarm Pro installed on an Android device
- Yoctopuce Yocto-Knob sensor (Valarm compatible sensors are available at shop.valarm.net)
- A magnet switch for each window (up to 5 per Yocto-Knob sensor)
1. Connect your phone or tablet with the Yocto-Knob using a USB OTG cable. Use the lead wire(s) and ground wire to connect the Yocto-Knob to the magnet switch (alligator clips used in demo picture). The magnet switch will be attached to a window after Valarm app configuration.
2. In the Valarm app, launch the menu for All Settings > Yoctopuce > Knob.
3. Verify that any channels using trigger switches like the magnets are set to “Open triggers MAX” as shown in the photo below. In this example I’m just using Channel 1 but the Yocto-Knob has 5 channels available for any combination of electrical resistance sensors.
4. Now we’re ready to set up the windows for remote monitoring (a Sony Xperia U ST25i phone is shown in the photo below). Attach one piece of the magnet switch to the window and the other piece to the wall.
6. The moment your window is opened Valarm alerts you since you chose the “Open triggers MAX” setting in step 3.
7. The Valarm app with the Yocto-Knob supports up to 5 channels so you can set up a station for remote monitoring and data acquisition in all kinds of situations. Below is a picture with Valarm monitoring potentiometers, a force-resistive sensor (measures pressure and weight: how hard is it being squeezed or stepped on?), and liquid detection / flood alerting (Trader Joe’s chocolate almond milk in this example). Use photo-resistors, e-tape, or any combination of sensors you like to monitor anything, anywhere!
