TTN Smart Sensor (Minol-Zenner) Technical Overview

1. Introduction:

The TTN Smart Sensor is an innovative solution by Minol-Zenner which is designed to streamline the consumption data collection for water, gas, heat, and electric systems with smart metering solutions to deliver exact consumption readouts.

2. Working Principles:

The working process of the TTN Smart Sensor relies on the transmission of meter reading data at regular intervals using the LoRaWAN (Long Range Wide Area Network) technology. The device collects data from the meters, processes it, and transmits it wirelessly to a gateway. This radio transmission is capable of covering a broad area and can penetrate deep into buildings, thus allowing for remote meter readings.

3. Installation Guide:

Installing a TTN Smart Sensor by Minol-Zenner involves mounting the sensor on or near the appliance which requires monitoring. After ensuring that the device is powered on and correctly configured, it needs to establish a connection with the gateway. The sensors are robust and can be installed directly, without requiring an additional external power source.

4. LoRaWAN Details:

LoRaWAN technology is a protocol designed for wireless battery-operated devices. It can communicate over long distances (2-5km in urban areas and 15km in ideal conditions) with minimal power usage. The TTN Smart Sensor uses the LoRaWAN Class A protocol, allowing bi-directional communication, wherein each sensor's uplink transmission is followed by two downlink receive slots.

5. Power Consumption:

The TTN Smart Sensor is a low-power device, designed to function for years on its internal battery. The power consumption depends on the number of daily transmissions and the distance to the gateway, however, in most of the applications, it’s lower than 1.5 W.

6. Use Cases

There are many potential use cases for this smart sensor, most notably in:

• Utility Providers: Real-time data collection of utility meter readings that reduces manual meter reading costs.
• Smart Homes: Easy monitoring of energy usage, enabling better energy-saving practices to reduce bills.
• Smart Cities: They can be used for large scale deployments for monitoring water, gas, or electricity usage.

7. Limitations:

Like any other technology, there are also a few limitations:

• Without access to a LoRaWAN network, the sensor's data transmission will not function.
• The sensor could deliver inaccurate results if it's near devices producing high electromagnetic interference.
• Device coverage is lower in heavily built environments due to signal attenuation.
• The longevity of the battery will be significantly affected by the frequency of message transmissions.

Overall, TTN Smart Sensor (Minol-Zenner) is a promising solution for remote meter reading, monitoring, and smart city development. Although it has a few limitations, its long-range and low-power consumption, along with precise and reliable data transmission, make it a viable option for a range of use cases.
