The External Telemetry Hardware

The Bluetooth Emitter, the Acquisition Unit and the Analysis Server: the intelligence of DECRO®

The emitter contains the electronic used to collect the 3 biosignals, and the latest generation of Bluetooth low energy radio module to transfer data. We have made all efforts to miniaturize the electronic and to minimize the weight supported by the animal, without making trade-off on signal’s quality and autonomy.

The acquisition unit and/or the analysis server (depending on the choosen range) contain our proprietary software and receives the biosignals send by the emitter thanks to the Bluetooth which has been designed to comply with industrial ElecroMagnetic Compatibility (EMC) requirements. It is a complete plug-and-play experience, without harassing setup or license management on every user’s computer. 

High performance Bluetooth low-energy

Robust radio module and advanced protocol to prevent data loss with data buffering capability of several seconds and automatic acquisition resume in case of disconnection

No cross-talk of signals

No cross-talk of signals during multiple animal recording, allowing several devices in the same cage and room

Transmission range up to 10m

The emitter has a transmission range up to 10m in open field. The acquisition unit needs to be in the same room

The Bluetooth communication protocol embedded in our solution has been extensively tested in multiple situations and has demonstrated its reliability.

Emitter main features

Embeds 3 physiological sensors

The emitter embeds a high-resolution ECG (24 bits, 500Hz), a high-resolution respiratory inductive plethysmography (32 bits, 200Hz), and a 3D accelerometer (16 bits).

Optimized weight (15g) and ergonomics

The emitters, with its battery, only weighs 15g and the ergonomics is optimized to allow the animals to express their normal behaviour.

USB rechargeable batteries

The emitter is provided with two USB rechargeable and replaceable batteries. They are reusable without repackaging.

Acquisition unit and analysis server main features


DECRO Start and Advanced range

The setup will differ depending on the number of animals you are recording simultaneously and therefore the solution you have (Start or Advanced). 

1 acquisition unit is needed for 2 animals and up to 4 animals to record simultaneously, you will additionally need 1 analysis server.

The acquisition units and the analysis server work together in a unified way, exactly as a single hardware. Check our catalog to know more.

Plug & Play solution

The acquisition unit is very simple and rapid to setup. There is no need to install anything on your computer since everything stands in our hardware. 

Robust hardware and small footprint

Designed to resist to harsh environment and operate on 24/7. The acquisition unit has a low energy consumption and a fanless design to make it dust proof and noiseless.
