TTN Smart Sensor (Noah) Overview
Working Principles
The Things Network (TTN) Smart Sensor, Noah, is an Internet of Things (IoT) device designed to gather telemetry data from its environment. The sensor uses a combination of hardware-based sensors and software algorithms for data acquisition and analysis.
The sensor's operation is founded on a few fundamental concepts:
- Telemetry: The sensor continuously records data from its environment based on configured reading intervals.
- Edge Processing: The device performs some level of data processing on-device to reduce the need for transmission, saving power and improving network efficiency.
- Low-Power: The sensor is designed with power efficiency in mind, using a power source optimally to ensure long battery life.
Installation Guide
The sensor is designed for easy setup and installation. Below is a step-by-step guide:
- Unbox the sensor and ensure all the parts are intact.
- If required, connect the sensor to the necessary power source.
- Position the sensor in the location where data is to be gathered.
- Connect the sensor to the LoRa gateway or network following manufacturer's instructions. This usually involves scanning a QR code or supplying a serial number.
- Once connected, configure the sensor's parameters like reading intervals, transmission intervals, etc. as needed.
LoRaWAN Details
TTN Smart Sensor (Noah) is built to use LoRaWAN (Long Range Wide Area Network). LoRaWAN is known for its ability to provide connectivity to IoT devices over long distances with very little power consumption.
TTN Smart Sensor (Noah) uses this technology to transmit the data gathered by it to a centralized server. It has an operating frequency range that is dependent on the region - 868 MHz for EU and 915 MHz for the US.
Power Consumption
The sensor has a very low power consumption rate. It operates on a battery which lasts several years before needing a replacement depending on the sampling and reporting rates. It employs a low-energy sleep mode after data transmission to conserve battery life.
Use Cases
TTN Smart Sensor (Noah) has a wide range of uses, from industrial applications to home use:
- Environmental Monitoring: The sensor can be used for temperature, humidity, and pressure monitoring.
- Asset Tracking: Use for tracking location of equipment or goods as they move in a warehouse or across supply chain.
- Smart Agriculture: Monitoring soil health, crop health, and optimising irrigation.
Limitations
Despite its numerous abilities, the Smart Sensor (Noah) also has few limitations:
- Range Limitations: While LoRaWAN has a longer range compared to other wireless technologies, it can still be affected by obstructions or interference, reducing the effective range.
- Data Rate: LoRaWAN, due to its low power use and long range, has a lower data rate. Thus, it's not suitable for applications requiring real-time data streaming.
- Dependency on Gateway: The sensor needs a LoRaWAN gateway to function. Without gateway coverage, it cannot operate.
Despite these limitations, TTN Smart Sensor (Noah) remains a very proficient IoT device, offering a mix of range, low power use, and versatility that make it an incredible tool in many different applications.
