Monnit wireless accelerometers can be used in a host of applications where knowing impact, vibration, inclination, etc. is required.
The wireless accelerometer - Impact Detection sensor activates when g-forces are exceeded by a user defined threshold – up to 8 g-force. The user can key in the desired threshold for the g-force trigger. This sensor has two operation modes that can be also selected by the user: High Performance and Low Power. High Performance has an output data rate of 800 Hz with the High Pass Filter cutoff at 16 Hz while the Low Power has an output data rate of 12.5 Hz with the High Pass Filter cutoff at 0.25 Hz.
The standard version of this sensor is powered by two replaceable 1.5 V AA sized batteries (included with purchase). This sensor is also available with a line power option. The line powered version of this sensor has a barrel power connector allowing it to be powered by a standard 3.0 - 3.6 V power supply (Included with Line Power option upgrade). The line powered version also uses two standard 1.5 V AA batteries as backup for uninterrupted operation in the event of line power outage.
Power options must be selected at time of purchase, as the internal hardware of the sensor must be changed to support the selected power requirements.
* Actual range may vary depending on environment.
** Battery life is determined by sensor reporting frequency and other variables.
