which provides cellular Internet offers connection anywhere with the availability of mobile network coverage. These shields are:
We are back again with another tutorial on Sixfab GSM/GPRS Shield. This has been designed with Quectel M66 GSM/GPRS module which is based on 2G chipset and bears optimal performance for SMS and audio service. It basically work with AT commands. To know more about the AT commands of Quecctel M66 you may visit Quectel site. Read More
Sixfab NB-IoT is another member of our Nb-IoT Shield family. This can be connected either with USB or you may also use any micro controller(Arduino, Raspberry Pi, Orange Pi etc. ). For this tutorial we are going to use Raspberry Pi. Here we will be sending data obtained by our Raspberry Pi from Ultrasonic Waterproof Range Finder(JSN-SR04T-2.0) and send this data over UDP.
Before you get started make sure you have done your router configuration as mentioned in previous tutorial step 1-10.
We are here again with our Sixfab Raspberry Pi NB-IoT Shield Tutorial. As mentioned in the product details that there are built-in Temperature, Humidity and Light sensors along with relay and USER led on the shield. So we will be showing you how to access all of them in this tutorial and sending the received data over local server. You can also try this with remote server. Read More
Sixfab Raspberry Pi NB-IoT shield is a narrow band IoT (NB-IoT) shield for Raspberry Pi. NB-IoT is very suitable for IoT applications with low power consumption. Shield also has the built-in 3-axis accelerometer, temperature, humidity, light sensors, optocoupler, and relay. If you like, you can also add your own sensors using the built-in 4 channel ADC.
In this tutorial we will learn how to get GPS data using 3G, 4G/LTE shield.
GPS(Global Positioning System) also known as NavStar indicates the position of an individual on the earth. The Satellites orbiting around the earth sends precise details of their positions at a regular interval of time. Once information are received by a GPS receiver, a GPS receiver can pinpoint the location.
There are also navigation systems which support in their in specific regions like GLONASS provided in Russia.
For this tutorial we will need
a. Raspberry Pi
b. 3G, 4G/LTE Shield
c. 3G, 4G/LTE module (for 3G UC20 and for 4G EC25 is used)
d. PCB Mobile Antenna (2x)
e. GPS Antenna
Here it goes
Previously we have used GPRS shield to establish internet connection. Now we will use 3G, 4G/LTE shield for PPP internet connection. In order to make a 3G and 4G connection we will need to use Quectel UC20 and Quectel EC25 modules respectively.
As this tutorial is for 3G-4G/LTE PPP Internet connection, we will use Quectel UC20 3G module or Quectel EC25 4G/LTE module, which are series of powerful function UMTS/HSPA+ module and series of LTE category 4 module optimized specially for M2M, IoT and multimedia applications respectively. Due to rich set of protocols, industry-standard interfaces and abundant functionalities extend the applicability of the module ti a wide range of M2M and IoT applications such as industrial router, industrial PDA, rugged tablet PC, video surveillance and digital signage.
