This video shows how to establish a peer-to-peer wireless LoRa communication. With a simple example based on Arduino, it explains how to update the data from a DHT11 temperature and humidity sensor to the ThingSpeak cloud. Before being able to send data from sensors to a cloud server, a beginning developer may need targeted assistance to quickly learn LoRa and IoT technology. That's why Elektor has chosen the new Dragino LoRa IoT Development Kit. Soon you too will turn your ideas into practical applications on the Internet of your own Things.

A Wide Area Network connects far remoted devices to the Internet through gateways. LoRa is such a subscription-free communication standard, supported by many companies. There is no overlap between LoRa and WiFi or Bluetooth. The latter have a very short range, LoRa a very narrow bandwidth. Since it is used mostly with sensors, the traffic can be slow and mainly unidirectional. LoRa also supports peer-to-peer communication.

For your IoT experiments, if you want to connect many wireless sensors to your home automation system for example, you need a long range wireless network with low price. And a gateway nearby. Try the Dragino LoRa/GPS_HAT module together with a RPi. It provides ultra-long range spread spectrum communication and high interference immunity whilst minimising consumption... and costs !
