Low Power IoT Network using Arduino and Long-Range LoRa
In continuation of my work with the nRF24 IoT Sensor Network, I decided to test a couple of RFM95 (LoRa) modules I had in my lab. This time, instead of using the MySensors library, I opted for a more lightweight library called RadioHead for Arduino. The objective was to evaluate the range of these LoRa…

ESP8266 Low Power Engineering for Optimizing Battery Efficiency
One of the biggest advantages of the ESP8266 is its popularity within the open-source community and its low price. However, for battery-powered IoT applications, ESP8266 low power performance is a concern. The WiFi radio consumes at least 70mA while active. Additionally, the ESP8266 takes 6 to 10 seconds to boot and connect to a WiFi…
