Previously, I covered the Dragino LG01 Single Channel LoRaWAN Gateway, a low cost solution good for testing basic LoRaWAN communication setups. I needed a better gateway and I was about to go for the german IMST IC880A gateway when I stumbled upon a Chinese variant named RAK831, that was cheaper and offering the same features. The RAK831 and the IC880A boards are almost identical in terms of Semtech chips used…
The Microchip RN2483 and the RN2903 are Low-Power Long Range LoRa® Technology Transceiver Modules, in the same package and Pin compatible. The RN2483 is intended for the 433 MHz and 868 MHz Frequency Bands (Europe), while the RN2903 is for the 915 MHz Frequency Band (US, Taiwan). I used the RN2483 in my first LoRaWAN project, some time ago. While LoRaWAN technologies have seen an impressive recent boost and Microchip’s…
I already covered the impressive LPWAN LoraWAN technology with a proof of concept remote air quality monitoring unit based on the BME680 from Bosch and the RN2483 from Microchip, in a previous post. The device, capable of measuring temperature, humidity, pressure and VOCs can run for months on a single cell battery, thanks to the low power LoraWAN communication solution. It can send real time data on distances up to…
Some of the best moments are those when exciting technologies come together to create even greater products or results. This is such an example. Taking advantage of the latest IoT advancements, the LoRaWAN is a network protocol intended for wireless battery operated Things. Geographic areas ranging from the size of a city to the size of an entire country can be covered with just a few LoRa base stations, finally…
