Built on Golioth: A Cellular Data Logger by AL2TECH

Today we are highlighting the AL2LOG, a cellular data logger by Golioth Design Partner AL2TECH. This is the latest entry into the Golioth Solutions Marketplace, announced last week. This device is a great way to capture a wide range of input data from an industrial setting, especially when you don’t know every type of measurement you want to take at the start of your project. You can deploy an AL2LOG to your factory floor or rugged environment and start monitoring signals and processing data on the cloud.

The AL2LOG is a general purpose logger

Let’s take a look at some of the specifications and use cases for the AL2LOG.

A range of input options

The name of the game with the AL2LOG is flexiblility. That’s why you can interface it with the following signals from all types of sensors

• GPIO
  • Digital Input
  • Dry Contact
  • Pulse Counter
• CAN
• RS-485
• 4-20 mA
• 0-10 V

Industrial users will recognize many of those signal types. Golioth has some Reference Designs that include more bespoke monitors targeted at specific verticals, like the CAN Asset Tracker and the MODBUS (RS-485) Monitor.

When you need to send control signals out into the world, you can do so with a programmable
power output (5 to 12V) for devices downrange of the logger, open drain outputs, as well as a 220VAC smart switch.

The device is powered off of two massive D-cell batteries for a 10 year battery life, but can also be powered from external sources when you want an even longer lifetime (or higher power utilization).

Built for speed, but not high power drain

While this design is based around the nRF9160 LTE-M / GPS / NB-IoT modem, it also relies on a higher speed ADC for advanced data capture. This Ultra Low Power acquisition and logging subsystem utilizes a true 14 bit ADC, and can efficiently capture high resolution data and cache it before sending it back to the Golioth Cloud. Utilizing Golioth’s new Batch Pipeline Destination, it’s super easy to bundle up a slug of readings and send them to the cloud to be unpacked later. Read about how Mike showcased sending data in batches.

A Case Study on AL2TECH’s Client Work

We recently profiled AL2TECH and their work with Hubwater, also seen in the video above. Hubwater is reducing waste and improving water distribution at commercial locations in Italy and beyond.

Some key points from that case study include how quickly they were able to get up and running using Golioth, and how they get to continually offer new services to their clients by utilizing Golioth Pipelines and OTA.

More Solutions Coming Soon

This is only the second of many solutions in our Golioth Solutions Marketplace. We are excited to share additional work of our Design Partners and Golioth Reference Designs. If you have a solution you’d like to share with Golioth and the world, please get in touch!
