Update: RisingHF Gateway RHF0M301 with Loriot Community Network

It’s been about a year since I posted an unofficial manual for getting the Seeed Studio 915 MHz RisingHF Raspberry Pi gateway up and running with Loriot. In that time, I had hoped that there would be more resources available for enthusiasts to find information about setting up gateways, nodes and sensors. However, it looks like complete and reliable information is still hard to come … Continue reading Update: RisingHF Gateway RHF0M301 with Loriot Community Network

Seeed Studio LoRa Kit

Getting Started with LoRa

LoRa is a radio technology for long range, low bit rate communication among sensors (temperature, light, location etc…) and other IOT devices. The sensors send their data to a radio receiver known as a gateway. The leading protocol used by sensors and gateways to manage communications, frequency, data rate and security is known as LoRaWAN. The gateway transfers the sensor data to the cloud so … Continue reading Getting Started with LoRa

Pushing a bt.tn button

The Internet Button

While perusing the various channels on IFTTT recently, I came across one for something called “bt.tn.” My curiosity led me to a Finnish site that sells a very interesting product: a large pushbutton that can control anything that is connected to the internet. The bt.tn comes in various colors and has both Wi-Fi and cellular models. The operation from a user’s perspective could not be simpler. You … Continue reading The Internet Button

Sharing Data From the Netduino

As mentioned in an earlier post, I’ve been working with the Netduino microprocessor board, a .NET version of the open source Arduino. In preparation for designing a home energy monitoring system, I created a small project to measure and post data from the Netduino. The simplest circuit I could find consisted of a photocell and a resistor wired into one of the analog inputs. Every … Continue reading Sharing Data From the Netduino
