The Signal System

Measuring the physical world of construction in real-time.

Embeddable.
Wireless.
Smart.

Continuous data when you need it.
At the heart of the Signal System is the Signal Sensor v2:The latest iteration of our fully wireless embeddable sensor that measures in-situ concrete temperature and strength data, uploading it to the cloud in real-time via the Signal Live Hub or periodically with the smartphone app. 

With v2 we’ve added the ability to connect Tails, embeddable sensor extensions that connect onto a new port on v2. This opens up the potential to measure an endless number of new data types.

Fully embeddable & wireless

The Signal Sensor uses Bluetooth to transmit data to the Converge app on your smart device or to the Signal Live Hub which transmits data to the cloud automatically. No wires, no more awkward trailing thermocouples or routes for water ingress.

Continuous & real-time data

The Signal Live Hub automatically collects and transmits data from the embedded Signal Sensor. No more manual data collection, just continuous real-time data.

Designed for easy installation

The sensor’s meticulously designed signature curve is compatible with most rebar sizes. A wide islet, non-slip surface, and cable tie channels make it easy to secure the sensor in position.

Connect other sensors: Tails

Tails are cabled sensors that connect to the wireless Signal Sensor v2 via the side port. Tails can take many forms, from daisy-chained thermal Tails to tilt sensors and strain gauges. Tails open up a vast new world of measurable physical data, all while operating within a wireless embedded system.

Features

The fully embedded Signal Sensor v2 measures in-situ concrete temperature before sending it to ConcreteDNA where it is calculated into concrete strength data. ConcreteDNA provides a real-time view of the strength data, contextualises each pour’s status in a BIM model, and provides >95% accurate AI curing predictions - all viewable from any device, anywhere, at any time.

Learn about ConcreteDNA

Structural health Tails connect to Signal Sensor v2, creating a fully embeddable, automated, and wireless way to measure performance. With this data, StructureDNA can pre-emptively detect dangerous QA issues.

Easy set up

Remove the card

Once removed, the sensor will activate. TheLED will begin to flash every two seconds.

01

Register your sensor

Install and launch the Converge app, create or select a pour, and add your sensor by scanning the QR code.

02

Install the sensor

Secure the Signal Sensor with a cable tie in a locationthat will be covered by less than 200mm ofconcrete.

How deep should the sensor be installed?

A plus icon

We recommend installing the Converge Signal sensor up to 100mm below the concrete surface, and making sure the face with the QR code is facing up.

What range of wireless connection should I expect from the sensor?

A plus icon

Once in concrete, the sensor range could be up to 8m, depending on the rebar configuration around the sensor and the sensor installation depth. Please ensure that you are closer than 8m and the Converge app is on your phone screen (not background) when communicating with the device.

Can I collect measurements when my phone is not connected to WiFi or data?

A plus icon

If you can't access the internet where the sensors are placed, the mobile app will download the measurements over Bluetooth and store them locally on the phone. But make sure to connect your phone to WiFi or mobile data, as soon as you can. Then, open the Converge app to upload the stored measurements

How long do I need to wait to collect all the data from a Signal sensor?

A plus icon

The app takes about a minute per day of sensor readings/data. For example, if the last collection was done on Monday, and then you go to collect data again on Thursday, there will be three days of data to be collected on the device. This data collection will take around threetwo minutes or less.
