Things used in this project:
Introducing NCD’s long-range wireless temperature-humidity sensor, boasting up to a 28 Mile range using a wireless mesh networking architecture. Incorporating the Honeywell HIH9130 temperature-humidity sensor transmits highly accurate temperature and humidity samples at user-defined intervals.
The onboard temperature sensor is rated for -25°C to 85°C or -13°F to 185°F and the humidity sensor is rated for 0 to 100% RH. It can be powered by just 2 AA batteries and an operational lifetime of 500, 000 wireless transmissions. Battery life can be extended up to 10 years depending on environmental conditions and the data transmission interval. Optionally, this sensor may be externally powered.
With an open communication protocol, this IoT wireless temperature humidity product can be integrated with just about any control system or gateway. Data can be transmitted to a PC, a Raspberry Pi, to Microsoft Azure® IoT, or Arduino. Sensor parameters and wireless transmission settings can be changed on the go using the open communication protocol providing maximum configurability depending on the intended application. The long range, price, accuracy, battery life and security features of Long Range Wireless Temperature Humidity Sensor makes it an affordable choice which exceeds the requirements for most of the industrial as well as consumer market applications.
Steps to Send Data to LabView Utility
- At first, To visualize the data, we need a Labview utility application.
- To use this UI, you will need to install the following drivers:
- Install run time engine from here for 64-bit driver and 32-bit driver.
- Install NI Visa Driver.
- Install Labview Run time serial driver and LabVIEW Run-Time Engine.
- Getting started guide for this product.
Setting Up Node-Red.
Now that you have sensors running, we need a way to do something useful with that data.
- First of all, you’ll have to install Node-Red.
- Once that’s done, you’ll need to enter your command line, or Power Shell for Windows users, navigate to the directory Node-RED is installed in.
- Now type “npm I ncd-red-wireless node-red-dashboard“. This will install the nodes required to receive data from your wireless sensors and you can start Node-RED once this is done.
- To start node server write node-red in the command prompt or terminal and press enter.
Steps to Build the Flow:
Step 1: At this point, you’ll be viewing a large blank flow with a long list of nodes on the left-hand side, this sidebar is called the palette.
Step 2: Go ahead and drag a Wireless Gateway node over to your flow canvas to get started.
NCD-red-wireless Provides the nodes that manage the serial connection, parse incoming sensor data, filter it by specific parameters, and allow you to configure the wireless sensors.
Step 3: Finding Your Wireless Sensors:
When you’ve delivered the node you’ll be able to view the info tab, which contains records about the node’s capability, this tab is well populated for maximum node-red packages and consists of treasured statistics, often you will now not want to view any other documentation outdoor of the info tab, so hold it in thoughts even as you’re building your flows when you have a question approximately how a node works. The next element we want to do is configure the node, when you first add it you’ll note that there is a small triangle at the top right corner next to a blue dot, the triangle indicates that the node wishes extra configuration, the blue dot indicates that the node has no longer but been deployed as part of the flow.
- Double click on the node to open up the configuration options.
- Click on the pencil icon next...
