Valarm Classic

NOTE: Devices running Android 3.1 or newer could use Valarm Pro, which also includes support for external USB sensors on devices equipped with OTG/USB Host mode.*

Valarm is Industrial IoT. You can use Valarm to track almost anything via GPS, and to monitor almost any remote environment via sensors. Commercial fleet managers use Valarm as a vehicle or container-tracking device with additional sensor information. Scientists and hobbyists use it as a remote environmental monitor. Consumer uses include a motion-sensing or sound-sensing, GPS-tracking, anti-theft alarm and tracking device, or a powerful property monitor.

Android phones and tablets are inexpensive and readily available: Valarm allows you to use them in powerful new ways. Consider acquiring a dedicated device to use Valarm to its fullest potential.

Valarm monitors any or all of the built-in sensors on your phone or tablet to create an all-in-one tracking device and remote environmental monitor.

Built-in sensor support includes:

- Accelerometer (motion, shock)
- GPS (speed, geofencing: distance from target or origin)
- Ambient light sensor (if equipped)
- Microphone (audio)**
- Presence of external power (charger present/powered)
- Remaining battery life

Valarm will also interface with most Bluetooth OBDII adapters to monitor a vehicle's status, and tie that data to its current location via GPS. OBD2 sensors currently include throttle position, speed, engine RPMs, and coolant temperature. See for more details about Valarm's OBDII support.

Valarm responds to configurable "triggers" - these are limits set by you on each sensor:

- Send SMS/text message
- Send email
- Post to the Valarm website (
- Play an alarm sound
- Take a photo
- Record audio**

In other words, you can configure Valarm to send you a text message, an email, and post to your account on, when any sensor is triggered, for example:

- Your vehicle travels too far, too fast, or too close to an area (geofence), or the accelerator is "floored" or the engine raced (OBD2)
- Someone steals your bag of camera gear / guitar / motorcycle
- The lights go out on your reef aquarium or hydroponics

The Valarm interval timer allows you to record the status of all configured sensors at regular intervals (data logger), including taking photos and recording audio**. This allows you to graph all values on the website, as well as plot all locations on maps.

Text and email messages include the GPS location, and the value reported by the sensor. Other responses configure Valarm to record audio** or take photos when someone is tampering with your property. On devices with cellular service, the Valarm SMS remote control system allows you to arm/disarm with a password from another phone. Valarm can even “call you back” when you send it your password and the “callMe” command.

Valarm integrates with to provide mapping, graphing, spatial and historical analysis, and export to CSV/KML for analysis in external programs like Excel, ESRI ArcGIS, MatLAB, Quantum GIS, and Google Earth (see for examples and tutorials). A basic account for a single device is free, and allows you to see all sensor values posted by your device, plotted on a Google Map. Subscriber accounts enable additional tools (details at and allow an unlimited number of devices to be monitored, recorded, and managed on the web.

* Valarm Classic is compatible with older devices back to Android 2.2, however ON NEWER DEVICES (Android 3.1+) THE CAMERA WILL NOT FUNCTION. Valarm Pro is designed to support these devices, and also includes support for USB-attached sensors.

** Audio recording is considered "beta" and known to be unstable on some devices.

Valarm includes a "Call-Me-Back" SMS remote-control command. This requires the "Make Phone Calls" permission! Valarm also sends/receives SMS/Text Messages!
