Low-Cost, IP67 Rated Battery Powered Bluetooth® Tag


The Guppy is a compact, rugged Bluetooth tag perfect for low-cost monitoring of assets. The Guppy Bluetooth integrates with other Digital Matter devices that support Bluetooth, or they can be used with your own Bluetooth mobile applications.

Why Bluetooth?

We have added Bluetooth to the Remora2, and upcoming G120 and Eagle. These devices can serve as Bluetooth 'gateways', and pass Guppy Bluetooth Tag data to the server.

The Guppy will transmit a beacon signal every few seconds, broadcasting: 
  • Device Serial Number
  • Digital Matter Manufactuer Code
  • Battery Voltage
  • Transmit Power (to be used with RSSI for range estimates)
  • Temperature
The Remora2, G120 or Eagle can receive these beacons when in range of a Guppy Bluetooth. 
Given these are GPS devices, and their location is known, the location of each Guppy can be approximated. 

The Guppy Bluetooth is low cost, compact, runs off just 2 x AAA batteries for up to 5 years, and won't require a SIM or data plan. Meaning it can be readily attached to almost anything to provide low cost asset location. It is particularly useful for low value or smaller assets where it may not make commercial sense to attach a device such as the Yabby GPS or Oyster2

Just some of the potential use cases

Automatic Inventory Management - If a Guppy Bluetooth is attached to each item of stock, the number of tags that report to a gateway device can be used to count the number at a location.

Monitoring equipment across multiple sites - With a gateway located at each site, the gateway which a Guppy is reporting to will indicate which site the tagged asset is located

Hire Equipment - Monitoring equipment entering/leaving the yard based upon whether it is in range of a gateway or not.

Bin Location Tracking - Knowing where the bins were dropped of and by which truck. The truck will contain a gateway device, and when a Guppy attached to the bin is 'lost' (out of range of the gateway) - the bin has been dropped off at this location. 

Trailer Tracking - with automatic scanning of which pallets are on the trailer. A gateway device would be attached to the trailer and a Guppy Bluetooth on each pallet.

  • Hardware Features

    Low-profile IP67 rugged housing

    The IP67 rated housing is made of sturdy ABS/Polycarbonate plastic to survive bumps and knocks and to survive many years in the sun and weather. UV stable and rugged


    L 80 x W 40 x H 18mm


    Up to 5 years on 2 x AAs!

    2 x standard “AAA” size batteries which provide a balance between size and capacity. Low-cost off-the-shelf alkaline batteries can be used or for applications that require extreme temperature or extra long-life we recommend that off-the-shelf 1.5V lithium batteries are used. These are readily available from retail outlets, for example Energizer Ulitmate Lithium.

    Operating Temperature

    -20°C to +60°C
    For operation in extreme temperatures, the device must be fitted with lithium batteries.


    BLE 4.2 as standard
    BLE 5 Optional (subject to MOQ)


    BLE 4.2 - up to 100m
    Option for BLE 5 - Up to 500m (+19dBm option) - subject to MOQ

    3 axis accelerometer

    Optional 3D accelerometer for movement detection and alerting (special factory run required) Not fitted as standard.
