Working Principles
The TTN Smart Sensor from Enless Wireless is a LoRa-based monitoring and communication device that uses wireless communication technology to send and receive data. It utilizes the characteristics of Long Range Wide Area Network (LoRaWAN), enabling long-distance communication between the sensor and the reception gateway. The sensor detects changes in the environment, converts the changes into an electrical signal, and sends it to the LoRa gateway. The collected data is then instantaneously uploaded to the Internet-of-Things (IoT) platform through LoRaWAN for further analysis.
Installation Guide
Before installing, ensure that the TTN Smart Sensor is within range of the LoRaWAN reception gateway. The sensor gets activated with a simple press of a button. Mount it in the desired location with the provided attachments, typically on a wall or any surface that allows the optimal capture of environmental changes. Stick to the moisture-free, low-temperature environments for longevity.
LoRaWAN Details
The sensor maintains a LoRaWAN Class A protocol standard enabling communication with the LoRaWAN network. It operates in different frequencies according to different regions; in Europe, it uses the 868 MHz frequency band, while it uses the 915 MHz band in the US. The sensor supports adaptive data rate (ADR) and can communicate with different types of LoRaWAN gateways.
Power Consumption
The TTN Smart Sensor is powered by battery and it has a very low power consumption due to its intelligent power management system. This contributes significantly to its extended lifetime. The power consumption rate varies depending on usage, data transmission frequency, and environmental factors. However, on average, it can last up to several years depending on usage and conditions.
Use Cases
TTN Smart Sensors can see usage in a variety of scenarios due to their versatile capabilities, for instance, in smart buildings for monitoring environmental parameters like temperature, humidity, CO2 levels, etc. They are great for farming applications for soil monitoring, or industrial plants to detect hazardous gases or leaks, or in hospitals for ensuring optimal and safe conditions. Moreover, they can also be utilized in smart cities for monitoring public services or environmental conditions.
Limitations
Despite its versatility, the TTN Smart Sensor does have some limitations. It relies heavily on the LoRaWAN gateway; hence, it requires an effective and stable communication range for optimal operation. Any obstructions or interferences in the communication range can affect its performance. Additionally, the sensor is designed for specific environmental conditions; exposure to harsh conditions (extreme temperatures, high moisture) can also impair its performance. Furthermore, if the frequency used by the device isn't free from disturbances in a given region, the communication may get affected. Lastly, while the lifespan of the battery is significant, once drained, it needs replacement, which can be a concern in remote or difficult-to-access areas.
In summary, the TTN Smart Sensor (Enless-Wireless) represents an excellent integration of LoRa communication technology, featuring various applications. However, the users should keep in mind the limitations and ensure a suitable operating environment for the device.
