In This Guide we will learn how to use any ncd.io wireless sensors.
Wireless Sensor networks have two main components
ncd build Gateways as well as Modems. If you are not sure if you need a modem or Gateway checkout this guide IoT Gateways vs IoT Modems – What’s the Difference?.
Modems — If you want to read data using a PC, Embedded Computer or any local machine then Modem will be an Ideal choice. ncd offers USB, RS232, RS485 and Ethernet Modem. Depending on your requirement you can chooses one of these.
For example if you want to collect data on a PC then USB modem will be the most ideal choice but if you want to collect data on a PLC or SCADA system then you might look into RS485 or Ethernet modem.
Gateway — If you are planning to push data to a cloud service or MQTT sever then you can look into ncd gateways. ncd offers Azure, AWS, MQTT gateways. MQTT gateway is most common and widely used in public or private cloud platforms.
If this is your first encounter with Wireless or IoT product then we highly recommend getting a USB modem with sensors.
If you have a USB, RS232,RS485 or Ethernet Modem then you can use ncd Alpha Station, Node red, Labview or Python lib to communicate with the Sensors. Here are the few steps you should follow when you are getting started with the software installation
Once the Alpha Station UI is open now its time to power on the Sensor.
If you get following error during opening the Alpha Station
Currently ncd offers two kinds of wireless sensors.
A. Indoor sensors ( Black Box)
B. Outdoor IP rated Sensors ( White Box)
Indoor Sensors — If you have an Indoor Sensor then you can power up the Sensor using External Power Supply or Batteries. If you are planning ot use the Sensor with External Power then apply the DC power to power port. Once power is applied press-release the reset button and sensor will start transmitting the data.
The alpha station will pick up the sensor data and display in the UI.
If you want to use with batteries then you will need to take the sensor lid off and change the power source to batteries. The sensor has a Power supply jumper/switch.
Outdoor Sensor –Outdoor sensor only come with batteries ( we can external power supply option as well on request). Like indoor sensors it also has the a power supply switch/jumper. This switch can be used to enable the power on the Sensors.
Once you have the run mode working and and want to chnage any parameters then you will need to put the sensor in configure mode.
2. Once you click on setup Alpha Station will open the config window.
How to Put Sensor In configure Mode — Sensor has two button.
A. Reset ( Marked as R)
B. CFG ( Marked as C)
In order to put sensor in configure mode press release the reset button and immediately hold the CFG button for 5-6 seconds and then release the cfg button.
Once Sensor is in CFG mode the Alpha Station will get a CFG message from the Sensor and will start to read its setting.
In the configuration UI following settings can be changed
Note : The min recommended Delay is 3-5 Sec.
If you change some settings and not sure what all you changed and wants to go back to factory setting then you can factory reset the sensor by following these steps
