Technical Overview: TTN Smart Sensor (Kamstrup)

Working Principle

The TTN Smart Sensor (Kamstrup) is an advanced IoT device designed by Kamstrup to collect data and send it to the network server via a LoRaWAN gateway. The sensor uses various parameters to detect environmental conditions and measurements, which it transmits to a connected device for further analysis.

The sensor works on the principle of Low-Power Wide-Area Network (LPWAN) technology by connecting to a LoRaWAN system. Its wireless IoT communication ability enables it to send data from distant or difficult-to-access locations, while maintaining low energy consumption.

Installation Guide

The TTN Smart Sensor comes with a plug and play setup, making its installation uncomplicated. The sensor needs to be correctly oriented (direction and tilt), with the arrow on the unit pointing towards the flow.

1. If a meter is replaced or a sensor is added to an already installed meter, it’s necessary to use an activation magnet to start up the sensor. The magnet should be moved from the far side to the sensor, and then across the front of the sensor. A blink from the sensor LED light indicates successful activation.

2. Further, the sensor must be configured on The Things Network (TTN). This requires the user to input the device EUI, application EUI, and the app key on the TTN console to link the sensor to the network.

3. Once all the required fields have been filled out and saved on the TTN platform, the TTN Smart Sensor is ready to function.

LoRaWAN Details

The TTN Smart Sensor utilizes LoRaWAN connectivity, a low power, secure, and long-ranged telecommunication protocol best suited for the transmission of small packets of data, which makes it ideal for IoT applications. The sensor operates at various global, regional, or country-specific frequency bands, which include 864-868 MHz (EU), 902-928 MHz (US), and others based on the region of deployment.

Power consumption

The TTN Smart Sensor designed for Kamstrup meters offers low power consumption, which makes it an ideal choice for remote or hard-to-access deployment scenarios where regular power supply might be inconsistent or unavailable. The sensor uses a lithium battery that can provide up to 10 years of operational life depending on usage and environmental conditions.

Use Cases

The TTN Smart Sensor finds its use cases in various domains:

1. Utility Metering: The sensor can be used in water, electricity, or gas meters to relay consumption details to a central server.
2. Smart Cities: The sensor can play a key role in various smart city applications like better waste management, smart lighting, and monitoring environmental parameters like air quality.
3. Agriculture: In modern farming, it can be used to monitor soil moisture levels, weather predictions, and track livestock movements.

Limitations

The TTN Smart Sensor has some limitations:

1. Signal Interference: Since it operates on the open LoRaWAN standard, there might be interference from other devices operating on the same frequency.
2. Limited Data Transmission: LoRaWAN prioritizes power efficiency and long-range connectivity, so the sensor is not suited for applications needing high-speed data transmission.
3. Power Source Dependence: It operates on batteries, so in remote areas, once the battery depletes, it may be challenging to replace it immediately.

Despite minor limitations, the TTN Smart Sensor (Kamstrup) is a powerful and adaptable IoT device that provides crucial data in various applications to make everyday life easier and more efficient.
