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

Using Node Red to Control the MCP23008

Relay control simplified If you haven’t already, make sure to go through the setup tutorial. Once you’ve finished that we’re ready to go! The MCP23008 is a Integrated port expander that controls eight I/O channels through the I2C bus. This is one of our favorite chips to get started with, it is simple to use, and provides some great interactive feedback through the I/O so you can see your project working very quickly. Naturally, when we decided to start building libraries for Node-Red, this was the first product we grabbed. We manufacture dozens of boards that utilize this chip, you can
