In this blog, we’ve discussed a few different ways to integrate sensors into a Peakboard application. We can find an overview of these articles in The hitchhiker’s guide to I/O devices. In today’s article, we’ll take a look at the ADAM-6051 by Advantech. The ADAM-6051 is a compact, Ethernet-based I/O...
Over two years ago, we published two articles about Shelly products: One about how to use the button and another about how to use the power plug. A lot of time has passed since then, and many readers have come back and have actually used Shelly products in a professional...
On this blog, we’ve explored many projects that use MQTT to communicate between Peakboard apps and sensors and other hardware and software entities. MQTT is a nice and easy option to couple all these entities together. Especially because there’s no need for the entities to “know” each other. They just...
In this blog, we’ve discussed a few different ways to integrate sensors into a Peakboard application. You can see an overview of these articles in The hitchhiker’s guide to I/O devices. In today’s article, we’ll take a look at a sophisticated and slightly more expensive type of I/O module—an IO-Link...
In part one and part two of our ProGlove mini-series, we discussed the basics of integrating ProGlove scanners into Peakboard applications. We used both the USB and MQTT modes to get the scan event and related metadata. We also discussed options to send feedback to the scanner operator, such as...
In the past few weeks, we’ve discussed two I/O modules provided by ICP DAS: the ET-2254 and the U-7560M. In this article, we’ll take a look at the Advantech WISE-4012. This module provides a network connection via Wi-Fi. It offers two digital-only outputs and four analog/digital inputs. We will look...
In this blog, we’ve explained how to connect various devices to Peakboard, and build beautiful applications. One family of devices is I/O devices. These are used to connect any kind of sensor, like light barriers, buttons, and temperature sensors. On the output side, we often see actors like traffic lights...
In the first part of our ProGlove miniseries, we discussed the basics of integrating ProGlove scanners into Peakboard applications. We used both the USB and MQTT modes to get the scan event, along with some metadata. In the third part of the series we will build a full blown use...
In a previous article, we discussed an I/O module made by the Taiwan-based company ICP DAS. In today’s article, we will discuss another I/O module from the U-7500 series: the U-7560. It has 6 digital inputs and 6 relay outputs. The main difference is that it supports OPC UA as...
ProGlove creates next-generation barcode scanners that are integrated into a glove, so the user can scan barcodes without having to pick up and put down a conventional barcode scanner. The scanner is always “at hand.” For readers who’ve never seen a ProGlove scanner before, here’s what it looks like: In...
ICP DAS is a Taiwan-based company that sells industrial components for automation. In today’s article, we’ll take a closer look at ET-2254, a 16-channel I/O module that provides digital input and output pins, and comes with a cool MQTT interface that makes it easy to create a stable connection to...
In this two-part article series, we discuss some best practices for integrating Peakboard with Node-RED applications. Most of the time, communication between Node-RED and the outside world happens through MQTT or HTTP. We will use the HTTP option: Part I - Real-time calculator - How to send information from Peakboard...

In today’s article, we will discuss narrowband IoT devices. Narrowband IoT devices are usually not connected to any kind of Wi-Fi or local company network. Instead, they use the cellular network to connect to a server. For technical details, see this Wikpedia article on Narrowband IoT. The device we will...
This article combines several technologies and explains how to use them. Here’s the goal: Every time a ticket is created in Zendesk, it should be sent to a Peakboard announcement board informing the viewer about the new ticket. Here are the steps to do it, with the help of n8n.io:...
