ALTA wireless accelerometers can be used in a host of applications where knowing impact, vibration, inclination, etc. is required. This model takes 3-Axis G-Force Measurements at 4096 count/g Sensitivity.
The wireless accelerometer - G-Force snapshot sensor activates at a set time interval (defined by user) and measures g-force along X, Y and Z axes. Primary use is as an inclinometer or tilt sensor. There are three operating modes, +/- 2 G, +/- 4 G, or +/- 8G. The data displayed is the g-force on each axis, e.g. X: 0.001 Y: 0.031 Z: 1.01.
ALTA sensors offer 3 to 4 times the range of standard sensor platforms, extending non-line-of-sight reach to an exceptional 1,000+ feet through walls (12-14 walls typical). Using Frequency-hopping Spread Spectrum (FHSS) also allows ALTA sensors to have better interference immunity from other wireless devices.
Superior power management provides ALTA sensors with almost twice the battery life of Monnit's standard wireless sensors. Monnit's AA sensors have a battery life that typically lasts 10+ years.
ALTA products employ Monnit's new Encrypt-RF Security (256-bit Diffie Hellman key exchange and AES-128 CBC encryption for all sensor data messages), so security is maintained at all communication points from sensor to gateway, gateway to software, then back again.
Integrated on-board data storage allows ALTA sensors to store data messages if communication to a wireless gateway is disrupted (power outage, Internet outage, or out of range). Messages that can't be delivered will be time-stamped and stored in memory (up to the last 512 messages) until communication with the gateway is restored, at which point the messages will all be transmitted.
Over-the-air updates allow ALTA products to be updated remotely if new fixes or features become available.
