Radiation is the transmission of energy through space in the form of a particle or wave. These can be generated by instruments or produced naturally. One of the most common uses of radiation is from radionuclides, or radioactive isotopes, that release radiation during decay, or degradation. These radioactive materials are often used for cancer therapy, research, and energy production.
Read More “Remote Radiation Monitoring”LoRaWAN is a great long-distance, low-power transmission protocol. One of the questions that often comes up after deploying a gateway and nodes is “what’s the greatest distance I can successfully transmit between my gateway and node?” You could watch your Application traffic on The Things Network as you move to strategic locations and see if packets appear. However, an automated approach to this could save time and allow you to cover more ground. To do this, you’ll need a node with a GPS to send its location and software to aggregate the received data on a map to show the node transmission locations. This way you can have the node automatically transmit at a rapid interval as you walk, cycle, or drive to various locations.
Read More “LoRaWAN Tracker and Mapper”I’ve been heavily involved with sensors and remote sensing for many years. Recently, I’ve become intrigued with remote sensing, and began my exploration with LoRaWAN. However, to start experimenting with sensor nodes, I would need a gateway to receive all my node transmissions (as well as send back any data to the nodes). Below is how I built and implemented my outdoor LoRaWAN Gateway.
