![]() The temperature and humidity data sent by the transmitter will be received via the Ra-02 module and displayed on the Arduino IDE’s Serial Monitor. For the receiver, we will use an ESP8266 Nodemcu development board with another Ra-02 LoRa Module. The transmitter will obtain temperature and humidity sensor from the environment using a DHT11 sensor connected to an Arduino Nano, and forward the data to the receiver via a Ra-02 LoRa module. The first tutorial, which we will look today, will focus on using LoRa in a peer-to-peer communication mode, while the second tutorial will focus on LoRa as a Wide Area Network.Īs a demonstration of LoRa being used for pair to pair communication, today’s project will feature two devices, one configured as a transmitter and the other, as a receiver. ![]() Several advancements like the outer-space based “Gateway” solution being deployed by FOSSAT and Lacuna is making it clear that it will have more impact on IoT than it currently does.Īll of these features and advancements make LoRa an important topic for electronics enthusiasts and over the next two tutorials, we are going to build projects to demonstrate how LoRa can be used as the means of communication in your IoT projects. While LoRa started with some level of uncertainty, it has grown into the communication means of choice for almost all types of IoT applications, even those who do not benefit from its low power consumption features due to their plugged-in nature. This is the standard on which platforms like the things network are built. The standard takes full advantage of all the features of the LoRa technology to deliver services including reliable message delivery, end to end security, location and multicast capabilities to users while ensuring the interoperability of the various LoRaWAN networks world-wide. LoRaWAN is a high capacity, Long Range, open, Low Power Wide Area Network (LPWAN) standard, based on LoRa technology and designed for LoRa Powered IoT Solutions by the LoRa Alliance. Peer to Peer communication allows two devices with LoRa radios to talk to each other in a manner similar to how two Bluetooth devices communicate, with the major difference being the fact that the range increases massively and less power is consumed.įor deployment as a wide area network, LoRa works hand in hand with Protocols like LoRaWAN which its usually confused with. As a Peer to Peer Communication protocol.This range achieved at a very low power which makes LoRa more suitable than other communication protocols, for remote, battery-powered IoT devices that are expected to run for months (or years) on a single battery charge. Using LoRa technology, devices can typically communicate over a range of 13- 20Km with the ability to go as far as 80KM in certain Line-of-sight setups, and as far as several 100s of KM from outer space as demonstrated by FOSSAT and Lacuna. ![]() Semtech leveraged on the power of the community via a consortium and transformed the technology into one of the key drivers of the current wave of digital transformation being instituted by IoT. Cycleo had developed a patented wireless communication technology called LoRa, which combined ultra-low power consumption with an effective long-range. Semtech, however, demonstrating an understanding the future of IoT, saw a potential game-changer when they acquired France based Cycleo in 2012. Several communication protocols exist, from WiFi and Zigbee to 2G, LTE, and even satellite communications, but each of them is usually plagued by one limitation or the other which makes them unsuitable for certain IoT use cases, with the major culprits usually being a tradeoff between range, power, and bandwidth. Selecting the right communication protocol is an important part of any IoT project as not being able to communicate with the server/device cloud quickly takes away the “I” in IoT and could lead to the ultimate failure of the project. ![]()
