Predictive Maintenance through a Real Time Dashboard

A real-time dashboard for monitoring Machine Health can help business owners and operators keep track of their machines to ensure they are running smoothly. By installing NCD Predictive Maintenance Vibration sensors, you can create a dashboard that sends alerts when it detects a problem with the machine. This will allow you to fix problems before they become bigger issues. Machine health is important to monitor because it can help you avoid costly downtime and repairs. By using a real-time dashboard, you can be proactive about maintaining your machines. Installing NCD Predictive Maintenance Vibration sensors is easy and they come with

How To Bring 4-20mA Loop Powered Sensors to the IoT World

4-20mA Sensors and IoT 4-20mA is one of the oldest and most used wired communication protocols out there. These types of sensors are easy to use, easy to set up, reliable, and noise immune. Almost every manufacturing facility will have numerous sensors that output a 4-20mA signal. Generally, these sensors connect to a PLC and from there users have to jump through a few hoops in order to take it to the cloud. There are two ways users can push data to the cloud: Install new sensors which can connect to the cloud directly Retrofit old sensors with IoT technology Types

Node-RED Dashboard – Enterprise 2-Channel Counter

In this article we’ll configure a dashboard for monitoring traffic through, and the capacity vs. occupancy of, a room. To set this up, we’ll be adding a 2-Channel Counter to our wireless sensor network (WSN), if this is your first sensor that’s ok too, I’ll cover the extremely short setup instructions for the WSN in the next section! If you don’t happen to have a convention center with turnstiles set up for testing, that’s also not a problem! Not to give away company secrets, but I’m using a couple of momentary buttons to build out the application on my desk since my boss wouldn’t spring for the optical turnstiles I asked for.

Configuring the Wireless Enterprise Line with Node-RED

In this tutorial I am going to give you a brief example of how to configure your Wireless Enterprise Line of sensors using our ncd-red-wireless Node-RED package. Some of our sensors have special configuration options that I will be covering as I build other tutorials, so if you have a sensor with options you need help with that isn’t listed here, please feel free to let us know on our Node-RED Community topic and I will get this updated as quickly as I can!

Node-RED and the Wireless Enterprise Line

Code-Free Programming If you’ve been following our recent forays into the latest of IoT, you are probably already familiar with Node-Red. If you haven’t, you’re in for a treat! In short, Node-Red is a visual flow builder that was developed with IoT in mind, you can think of it as a way to build a program without actually writing any code. In this article, we’re going to focus on our node-red-wireless package that we use to integrate our Wireless Enterprise Line into this amazing framework. If you are new to our Enterprise line of Wireless Sensors, check out the intro

Using Node Red to Control the PCA9536

GPIO in minutes If you haven’t already, make sure to go through the setup tutorial. Once you’ve finished that we’re ready to go! The PCA9536 is an 8-pin CMOS device that provides 4 bits of General Purpose parallel Input/Output (GPIO) expansion through the I2C bus. We manufacture multiple mini-modules that utilize this chip, you can check them out here. If you haven’t already, get your devices plugged in, on a Raspberry Pi, that means installing the adapter, hooking up the I2C cable to the In port on the Relay Board, and powering the board. On any platform without native I2C,

Arduino 4-20mA Current Loop Input Receiver Shield

Using Node-Red With the ADS1115

Input With Ease If you haven’t already, make sure to go through the setup tutorial. Once you’ve finished that we’re ready to go! The ADS1115 is a 4-channel, precision, low-power, 16-bit, I2C compatible, analog-to-digital converter. This chip is used in several of our ADC mini-modules, and also in our popular line of 4-20 mA current loop receivers. If you haven’t already, get your devices plugged in, on a Raspberry Pi, that means installing the adapter, hooking up the I2C cable to the In port on the board. On any platform without native I2C, we’re going to assume you have a
