Sensor MoJo measures vibration in arbitrary units called a “Vibe Index”. The algorithm for the Vibe Index is the result of detailed research into how to effectively sense when something is on and producing vibration. Lower numbers mean less vibration, and higher numbers mean more vibration. The emphasis of the index is to provide an indication when something is on more than accurately conveying an intensity. But, intensity of vibration is also captured and can be useful. For example, here are some measurements at Sensor MoJo HQ:

• Hepa Filter: 200
• Air Compressor: 5570
• HVAC Air Duct: 1900

But, ultimately you should just measure whatever you’re interested in with Sensor MoJo yourself, and then can use those measurements to set limits on alarms.
One other thing is worth mentioning about vibration: Sensor MoJo only samples once per minute. So, if a quick vibration happens, such as striking a table, Sensor MoJo may not pick it up. It’s much better at sensing continuous vibration.

Orientation

Sensor MoJo senses its orientation and reports that orientation as a number from 0-6. If Sensor MoJo were a person and the air holes were its head, the orientation would be:

• 0: Indeterminate.
• 1: Lying down on back.
• 2: Lying face down.
• 3: Standing.
• 4: Head stand.
• 5: Lying on left side.
• 6: Lying on right side.

You can alarm on these orientations by using the orientation alarm. For example, if you stick your Sensor MoJo to your garage door so that it is “Standing” (3) when it is closed and “Lying face down” (2) when it opens, you can set an alarm to text you when orientation 2 happens for longer than 10 minutes to let you know the door was left open.
