FAQ

Smart City

Is SDT Smart Hub waterproof?

SDT Smart Hub has an IPX8 waterproof rating, meaning it can be submerged up to 1 meter in water for 30 minutes. The Smart Hub needs an IPX8 rating, as it is exposed to raindrops and humidity.

What network does the Smart Manhole use?

The Smart Manhole uses LTE Cat M1. Unlike LoRa, LTE Cat M1 is widely available and does not require extra installation or devices. LTE Cat M1 is the optimal network for users, as it is both economical and adequate for the amount of data the Smart Manholes collect and upload.

Considering that the data the Smart Manhole collects is present underground, isn't it difficult to have constant network connectivity?

Unlike traditional manholes that are made of cast iron and concrete, SDT Smart Manholes are made of eco-friendly polymer material that allows connectivity.

Which telecommunications provider does the Smart Manhole use?

The Smart Manhole works with any telecommunications provider.

Is the SDT Smart Manhole powered by primary cell or secondary cell?

Both are compatible; however, we recommend using primary cell for easy and immediate replacements

How often do I need to replace the batteries in the manhole?

It depends on how often you want your Smart Hubs to collect and upload data; most of our customers replace their batteries approximately once a year.

What measures has SDT taken to make the batteries last longer?

We provide our users with the option of choosing how often they want the environment data the Smart Hub collects to be uploaded to the server/cloud. Some of our customers only need to check on the manholes several times a day-- other than those times, the Smart Manhole goes into "deep sleep mode" to minimize battery usage.

Do you provide a dashboard? Can the dashboard be customized? What can I do on the dashboard?

SDT provides an online dashboard you can use to remotely monitor your manholes on your laptop and phone. In the event of an accident, you receive alerts on the dashboard.

How do I register my Manholes on the dashboard?

Each manhole has already been registered on the dashboard for your account before shipping. Once you turn on the manholes, they will start sending data to your dashboard.

What types of sensors are compatible with the Smart Hub?

I2C, RS485, RS422, UART and any other sensor that supports serial network are compatible.

Which method does your gas sensors use?

The Smart Manhole is compatible with all methods, including NDIR(non-dispersive infrared), semiconductor, and electrochemical methods. Just speak with our sales to discuss your customization options.

Can I get alerts via messaging apps like Slack?

We currently support Slack. Alerts via email and SMS are also available at an additional cost.

Does your hardware connect to the cloud? If so, does it provide real-time connectivity?

The Manhole is fully functional and sends real-time data to the cloud as soon as it is activated.

Does the Smart Manhole use gateways/routers?

No, the SDT Smart Manhole has on-board LTE connectivity.

What types of gas can the Smart Hub detect?

The Smart Hub detects various types of gas including O2, CH4, CO, H2S, NH3, and NO2, depending on the model that you choose.

If the Smart Manhole needs maintenance, how much time will it take to repair the manhole?

Most maintenance takes up to three days. In the unlikely event that we don't have the parts needed due to supply chain issues, we will let you know in advance.

How much time does it take to install the Manholes?

It takes approximately an hour to install each manhole.
