Introducing the Autonomous Smoke Sensor, which uses optical detection method to detect smoke and LoRa WAN protocol to deliver alarms and messages. When the concentration of smoke rises above a pre-defined threshold, a loud audible alarm is raised locally and a LoRa WAN message is sent to the network server. Similarly, when the concentration of smoke drops below the threshold, the siren is silenced and another message (alarm-restore) is sent to inform the system that danger has subsided. Additionally, for device health supervision, the sensor sends heart beat messages at user-configurable intervals, which also contain information about the battery status. The sensor is powered from a single 9V alkaline battery, which lasts up to 3 years (subject to interval of heart beat message delivery configured by the user).

The Universal Sensor Module (USE) is designed to work with a wide variety of sensors providing two-state output signal. The USE has 2 inputs, each capable of working with the following types of sensor outputs: * dry contact * open collector * resistive * voltage source In addition, the USE also has a switched auxiliary power output (9V) for use with active sensors, which require supply voltage to operate. The user can define whether the reporting of the input states over LoRa WAN takes place at every state change or, instead, just as summary information for a given time period sent at regular intervals. The USE module is powered from a single 9V alkaline battery. The battery lasts up to 3 years, depending on the heart beat message period set by the user and current consumption by active sensors powered from the auxiliary power output (if any).

We are excited to present a concept of an electronic system designed to enhance the situational awareness of soldiers on the battlefield. Our specially designed sensor electronics and software, which leverage advanced signal processing algorithms and artificial intelligence (AI) techniques, significantly improve situational awareness in combat scenarios. The system is capable of detecting and classifying threats by analyzing the emission signatures of objects received by sensors that are integral components of the system. Furthermore, the system can be mounted either on a helmet or in separate capsules, which can be strategically deployed across the field by drones. These drones communicate with the operator via a robust long-range radio network that operates on spread-spectrum technology, making it resistant to interference.
