LOW-POWER AUTONOMOUS SENSING MODE LORA TECHNOLOGY-BASED MINIATURE ANTENNA

Due to the increasing number of applications which require efficient wireless communication systems, the integration of autonomous sensing applications and LoRa (Long Range) technology are attracting attention. This paper describes such a system based on a small antenna-based autonomous sensor with LoRa. To ensure efficient operability, there are transmitter and receiver section within the system. The section of the transmitter includes Arduino microcontroller with multiple sensors like heartbeat sensor, Mems sensor, pressure sensor and temperature sensor. Combined, these sensors offer a complete data set of environmental and physiological parameters. To achieve long distance and low power consumption data transmission to the receiver unit, a LoRa transmitter is utilized, accompanied with a security alarm for alerting purposes. The receiver part, consists of an Arduino microcontroller, LoRa receiver, and SPI module, it receives incoming data and sends it into a serial port for processing, analysis, and visualizing purposes. The power supply not only provides the system with consistent operation, even in remote areas. This showcases the benefit of role of LoRa technology when it comes to long range Let it be low power communication which the integration of LoRa is followed by health monitoring automation and multiple applications environment sensing. The developed system illustrates the usage of small and compact antennas to provide enough lost data fill due to fluctuations in maintaining less space. Initial testing suggests the system can be used to send accurate sensor data from long distances while consuming little power. This effort highlights the promise of Lora based autonomous systems for novel and extensible solutions for IoT based systems.
