Sentrius™ BT610 I/O Sensor + AC Current Assemblies

Recommended for New Design (RND)

Overview

Laird Connectivity’s Sentrius™ BT610 I/O Sensor is an open development device with Bluetooth 5 enabling you to develop the application to turn your wired sensors into IP67-rated battery-operated wireless nodes, providing robust, secure, and cloud ready messaging. Leveraging our BL654 module, it provides full Bluetooth 5 capabilities, opening up industrial and equipment monitoring applications. 

This configuration is designed with three-phase AC current measurement in mind, enabling customers to develop their own application on the device to monitor an electrical load profile remotely using a current sense method. It enables users to read and report sensor data to the cloud and define alarm conditions. 

There are two application development paths on offer; 

  • Using our Canvas platform firmware and sample applications as the basis for your application giving a head start on your development 
  • Ground up using Zephyr RTOS board files provided by Laird Connectivity

Software / RTOS Environment: 

  • nRF Connect SDK / Zephyr RTOS SDK for customizable applications 

Option for Canvas Device Management 

  • Application development environment to develop Canvas device management 
  • Advanced deployment tools including mobile app (Android and iOS) to register devices, and engineering services support. 

Device programming: via Laird Connectivity USB-SWD programming kit (453-00062-K1) and 6-pin Dupont connector male to female header jumper wire cable.

Three measurement ranges of AC Current Sensor for measuring the RMS current of an AC system: 

  • 0 – 20 Arms 
  • 0 – 150 Arms 
  • 0 – 500 Arms 

Comprehensive Certifications for FCC, ISED, CE, UKCA, AS/NZS, MIC 

Industrial temperature range (-40º to +85º C) 

Industrial IP67 enclosure 

Industry-leading support works directly with our engineers to help customize and deploy your design. 

Replaceable large capacity battery

Sensors and Cable Assemblies Sold Separately

The Sentrius BT610 sensor enclosures are not shipped with sensor cable assemblies for any of the focused applications outlined. Both the BT610 and required cable assembly must be ordered separately in the quantities required.

FAQ

Using STTY with the USB-SWD

These instructions are intended for Linux or Macintosh OS. They may work using WSL, Cigwin, or other bash style terminals in Windows although this is untested. 

It may be desired to communicate with a device attached to the USB-SWD without terminal emulation, I.E. Picocom, Screen, Putty.  This can be useful for writing bash scripts, or if you're using Zephyr's "west flash" and would like a quick way to check your output. 

  1. Verify you have the program "stty" available using the command "which stty", if this does not return a value you will need to install it.  Fortunately "stty" generally comes standard with Linux and MacOS.  
  2. Identify your serial device.  This can be done using the command "dmesg -w" then connecting the USB-SWD.  You will see output like this (In Linux).
  3. (Optional) Assign the device name to a variable, for example "DEVICE=/dev/ttyACM0".
  4. Configure "stty" to talk with the device "stty -F $DEVICE 115200 -echo -echoe -echok"
  5. To see output from the device execute "cat $DEVICE &".  This will send serial communication from the device to Linux's standard output.  The "&" is to run this program in the background.
  6. Now press the reset button on the USB-SWD, you should see the output from your device.  In this example the Zephyr "Hello World" example has been flashed to a BT510. 
  7. (Optional) if you would like to send commands back to the device you can use "echo" or add an argument to your shell, "foo() { echo -n -e "$1\r" > $DEVICE; }".  Now commands can be issued directly from the command line, for example "foo "my_command"" will send the string "my_command" to the device. 

Can I combine different sensor types on the BT610?

We offer the BT610 in different pre-canned sensor configurations. Unfortunately it is not possible to combine different sensor types, like ultra-sound plus temperature or temperature plus pressure. 

Where can I get BT610 internal production shipping battery documentation?

You'll find BT610 default battery shipping documentation attached to this FAQ.

Where can I find all different BT610 AC Current Sensors documentation?

You'll find all BT610 AC Current Sensors documentation attached to this FAQ.
