Advanced movement and shock monitoring with Bluetooth

Tempo Disc Bluetooth Movement Sensor Beacon and Data Logger is a small form accelerometer based sensor that can detect and log movement and/or shocks.  It is accurate, cost effective, smartphone compatible and can be internet enabled using internet gateways including our Cloud service.

Movement and Shock

Detects, timestamps and logs movement and/or shocks over a certain movement threshold set from 0 (most sensitive) to 255 (least sensitive).

Ultra low power

Ultra-low power movement sensor means the device can continue to log for over 12 months.

Two Channels

There are two channels that can have different level of sensitivities.  Ideal for monitoring both small movements and shocks at the same time.

Data Storage

20,000 data points or 10,000 for each of Channel One and Channel Two.  Logging interval from 1 second to 24 hours.

Bluetooth Low Energy

Bluetooth 4.2 with a range of 75 meters/245 feet line of sight.  Open Bluetooth beacon and logging API for custom development.


CR2032 coin cell that is easily changeable.  Provides up to 12 months battery life and more if in power saving modes.


Durable polycarbonate with soft touch TPE button.  Secured removable battery cover.  Optional silicon holder.

Advanced Features

Including airplane mode, device locking, calibration for temperature and humidity, real time clock for accurate logging, power saving modes, button disablement, alert tracking and more.
