**Update: The article below is from our legacy Android app! Valarm is Industrial IoT. The bottom line is that we'll help you, your teams, and your business organization with Industrial IoT and remote monitoring applications using Tools.Valarm.net.
We recommend using dedicated sensors hubs (e.g., GSM cell network or WiFi) with any sensors since they're much more reliable than Android telephones for your Industrial IoT monitoring applicationslike:
- Water Resources Management
- Air Quality
- Chemical Distribution and Tank Monitoring
- Fleet Vehicles, Trucks, and Trailers carrying Industrial Machinery and Equipment like Pumps, Generators, Motors, and Tanks
- Natural resources
- Hydraulics and Fluids Power Systems
- Oil & gas
- Bridges, Civil Engineering, Facilities, and Infrastructure
- Water Wells, Usage, and Groundwater Volume + Availability
You can use Valarm Industrial IoT, telemetry and remote sensor monitoring solutions with any of the following connector devices:
Tools.Valarm.net receives your organization's GPS-tagged, time-stamped sensor information via any internet connectivity like WiFi, ethernet, or cell network.
Your Industrial IoT sensors and remote monitoring hardware are available at Shop.Valarm.net.
Tools.Valarm.net is an open platform so you can use made by any sensor hardware manufacturer. Here are some favorites our customers deploy and remotely monitor with Tools.Valarm.net:

How do you charge a phone or tablet while running the Valarm Pro app with external USB sensors? This instructable from Team Valarm shows you how!
Why did we solve this problem? Valarm provides sensor and monitoring solutions that facilitate rapid deployment of real-time, ad-hoc, mobile sensor networks for remote environmental monitoring, mobile data acquisition, and asset / vehicle tracking. Valarm connects industry-standard sensors, makes them location-aware, and streams their data to the cloud or to private networks, using readily available commodity hardware. To do all of this our customers in over 30 countries around the world use these USB OTG + Charge Y cables to monitor anything, anywhere!
Some tablets (especially 10″ models) are equipped with a dedicated power jack. But most tablets (and all phones) charge via the same USB port that will be hosting your external sensors. A simple OTG+Power “Y-cable” is the solution. Below is a video demonstrating the Charging + OTG Y-cable being used to plug a phone into a USB sensor at the same time it is charging.
Where do you get one of these fancy Y-cables? The specification varies between manufacturers, but if you have a Samsung or Sony device, you are in luck!
Micro USB OTG Y-cables for the Samsung devices (e.g., Galaxy S3 and S4) are available in the Valarm store.
Want to build your own? You can make your own cable for a Sony device (e.g., Xperia U ST25) by following the instructions below or else you can buy a factory-made cable from us.
Micro USB OTG Y-cables for the Sony devices (e.g., Xperia U, SP, Z) are available in the Valarm store.
To build your own you’ll need a few tools and supplies:
- USB cables with Micro USB and full size USB ends
- Soldering iron and solder
- Wire cutters
- Wire strippers
- Dremel or something else to cut and expose a USB cable’s circuit board
- Resistor (To make a Sony compatible USB OTG+Charging Y cable use a 100K Ohm resistor. To make a Samsung compatible USB OTG+Charge Y cable use a 64.9K Ohm resistor (available here)
Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.
Step 1: Remove Cover From USB Male Plug
First cut off the head of a micro USB male plug and strip the plastic (we used a Dremel and wire cutters) to expose the circuit board.
Step 2: Solder 100K Resistor
Next solder one end of your 100K Ohm resistor to pin 4 (a.k.a. sense pin). To make a Sony compatible USB OTG+Charging Y cable use a 100K resistor. To make a Samsung compatible USB OTG+Charging Y cable use a 64.9K resistor (available here). The other end will connect to the pad labeled B (which is pin 5/ground).
Step 3: Strip USB Wires
Strip your USB cables with wire strippers to expose the 4 USB wires: red, green, black, and white here from a Samsung cable (other cable brands may use different colors!). One end will plug into your sensor (Micro USB male) and one into your power supply (Full or Micro USB Male or Female).
Step 4: Hot Glue and Heat Shrink
Cover this up with hot glue and/or heat-shrink tubing, and this end goes into the phone. The resistor signals to the phone that it should be a USB host, AND also draw power from the USB port. Now you can solder on your USB cable (e.g., male micro) that attaches to your sensor (solder the red, green, black, and white ends to their corresponding pads) and your USB cable (e.g., male full size) that plugs into your power source (solder only the red and black wires for this connection).
Step 5: Plug in Your USB Sensors (CO2, Thermocouple, IAQ, VOCs, Humidity)
All done: plug your sensors and charger into your device using the Y-cable you just made! For the cable in this picture we used a Mini USB connector to go from the device to a USB hub then all of the sensors (CO2, thermocouple, indoor air quality [iAQ, VOCs] in this picture) can be plugged into Valarm Pro at the same time!
Step 6: Factory Made Cables Available
1) You don’t feel comfortable doing any of the steps above (we’ve done it a few times and admit it can be a bit tricky and time consuming)
2) You would not like to take the time (you do get better at it after you’ve done a few but it still takes us almost an hour to do one by hand)
3) Don’t have the equipment to build one…
You can buy one of Valarm’s USB OTG charge cables in the Valarm store. Thank you for your support!
Step 7: USB OTG + Charging Y Cables for Sony Xperia
The cables are compatible with Sony Xperia phones and we have tested extensively with the Sony Xperia U ST25a and ST25i phones, which are the most inexpensive devices we have found that support USB Host and OTG. You can use the cable to charge an Xperia device at the same time as using your sensors, keyboard, mouse, game controllers, any other USB accessory. Many thanks to Przemyslaw Tracz (a.k.a. sonic_boom) for his website detailing how to do this!
This picture shows Valarm Pro running on a Sony Xperia U ST25i for remote monitoring with an air quality (volatile organic compounds, VOC) sensor and charging at the same time.
Step 8: Remote Environmental Monitoring, Fleet / Asset Tracking, Mobile Data Acquisition With Valarm
These cables are one of the keys to using Valarm for remote environmental monitoring.
We use these cables and solar panel power in Valarm deployments such as the La Brea Tar Pits, Los Angeles Natural History Museum, and vineyards / agriculture. You can use these Y cables with any combination of sensors to do things like air quality monitoring or anything else you want.
