Efento NB-IoT / LTE-M wireless sensors

Efento NB-IoT / LTE-M sensors were developed from ground up to meet customers’ needs. We collected feedback from different use cases, and developed devices which measure different physical values and seamlessly send the data over NB-IoT and/or LTE-M networks to Efento Cloud or any other cloud platform. On top of that, they are equipped in all software and hardware features a modern IoT device needs.

MODULAR DESIGN

Efento NB-IoT sensors are built on Efento’s modular platform which separates the communication and logic from power supply and sensors. Due to that we can quickly develop new types of sensors or modify the device to customer’s needs

BATTERIES OR EXTERNAL POWER SUPPLY

Depending on the use case, wireless NB-IoT / LTE-M sensors can be powered with batteries which guarantee up to 10 years of lifetime or by an external power supply

NB-IoT / LTE-M & BLUETOOTH LE

On top of NB-IoT/LTE-M wireless interface, sensors are equipped with Bluetooth Low Energy. This allows you to easily configure them with a mobile app and read all the measurements form device’s memory

TUNED ANTENNA

NB-IoT / LTE-M sensors are equipped with a tuned PCB antenna that provides the devices with good range. On top of that, sensors may be delivered with u.fl connector, so you can connect an external antenna to get event better signal

ENGINEERED ENCLOSURE

The enclosure was designed by us especially for wireless sensors. The size and the place of the ventilation was designed to provide the device with optimal air flow and quick reaction to the changes in the environmental conditions

Efento Cloud

NB-IoT sensors that work with any cloud platform

Taking measurements is just the beginning. The real value of the data can be explored on the cloud platforms which allow to collect, visualize, analyze the data and take actions based on it. Efento NB-IoT / LTE-M sensors work out of the box with Efento Cloud or can be integrated with any third party cloud platform.

EFENTO CLOUD

Efento Cloud is a powerful cloud based platform that allows you to collect and visualize data from Efento sensors, no matter if you have only a few or hundreds of them. Efento Cloud allows you to display the data on a map, as a table or on a chart, send SMS and email notifications and generate PDF / CSV reports with the data. On top of that, there is a mobile application that allows you to get access to all platform features with your smartphone or tablet. Learn more about Efento Cloud.

INTEGRATION

Efento NB-IoT / LTE-M sensors communicate with servers over standard protocols (protofbuf over CoAP). This allows you to integrate the data from the sensors directly to any cloud platform you wish. If you don’t want to do the direct integration, you can use Efento Cloud and its API to get the data and change sensors configuration. Visit our Support section to learn more about the integration.

Edge analytics that increases the battery lifetime to up to 10 years

Efento NB-IoT / LTE-M sensors have been developed with battery lifetime in mind. To decrease the number of transmissions to the server, the built in edge analytics module takes care of the data and sends it to the cloud platform only when necessary. Reduction of the number of data transmissions increases the battery lifetime up to 10 years

TRANSMISSION INTERVALS SETTINGS

You can set different measurement and transmission intervals for Efento NB-IoT / LTE-M sensors. If you don’t need a life data stream from the devices, they can store the measurements and send them to the server in larger intervals in order to increase the battery lifetime. Moreover, the data can be sent in confirmable or non-confirmable data frames. Non-confirmable data frames reduce the time needed to send the data and increase the battery lifetime

EDGE ANALYTICS

Efento sensors analyse the data and take the decisions, if an immediate action is needed. Temperature measured by the sensor is out of the safe range? Transmission will be triggered immediately. Humidity value increases too quickly? Data will be sent to the server right away. The logic and rules can be configured by the user including setting thresholds, moving averages and checking the differences between measurements.

Wide range of measured values

Let us know what you want to measure and we will provide you with a sensor. Each Efento NB-IoT / LTE-M wireless sensor can measure up to three values. Pick the values you want or check the list of ready-made sensors that we have on stock. Do you need to measure something which is not on the list? Contact us and we will check, if we can measure that.

Efento sensors offer a very high accuracy of the measured values. If you wish, at additional fee, we can provide you with a calibration certificate issued by a certified laboratory. Learn more about the calibration service.

Quick and easy deployment

We know that deploying thousands of IoT devices may be frustrating and time consuming. That’s why we designed Efento NB-IoT / LTE-M sensors to make the deployment process as easy as possible.

EASY INSTALLATION

Sensors are mounted on the wall with a double side adhesive tape with acrylic glue. It takes seconds to install a single device and the tape which is included with the sensor sticks to any surface. If you don’t want to stick it with a tape, you can simply use screws to mount it on the wall.

CONFIGURATION OVER BLUETOOTH LOW ENERGY

Initial configuration of the device is done with a mobile application, over Bluetooth Low Energy, so you can forget about cables and connecting the device to your laptop. During the setup, the application performs a test, to check if the device is able to communicate with the platform and if the signal conditions are right.

LARGE SCALE DEPLOYMENTS

We are ready for that too. When ordering a large batch of the devices, let us know what is the configuration that you need and we will set it up for you. Once you get the devices, they will start operating out of the box!

TROUBLESHOOTING

We all know, it’s part of the game… With Efento sensors, you can check the full status of the sensor (including the network status and the communication status) locally with a mobile application or diodes which signal the status of the device. On top of that, all the information, which may be useful for troubleshooting can be sent to the server, for remote diagnostics.

Secure over the air updates and remote configuration

Deploying IoT devices is only the first step. We are aware of that and have developed mechanisms that allow us to remotely update the firmware of the wireless sensors and change their configuration. No matter how your requirements will change, you will always be able to set the devices in the way you want.

FIRMWARE OVER THE AIR UPDATE

Efento sensors firmware can be remotely updated. In order to reduce the amount of data sent to the NB-IoT / LTE-M sensors, the update process is based on the difference mechanism, so only the packets of the firmware which have been changed are sent to the device. The whole communication between the server and the device during the update process is encrypted and both parties have to authenticate with their unique keys. This ensures the security of the whole updated process.

REMOTE CONFIGURATION

We know that when you deploy a large number of IoT devices remote configuration is a must. All the settings of Efento NB-IoT / LTE-M sensors can be configured remotely from the cloud platform. Do you want to change the measurement period of the device? No problem. Need to change the address to which the data is sent? We can do it. Moving devices to another APN? Let us handle that.
