Efento Bluetooth Low Energy wireless sensors

Efento Bluetooth Low Energy sensors measure various values and wirelessly send the data to smartphones or, through Efento Gateways, to Efento Cloud. Wireless loggers are equipped with large built in memory, and battery which ensures long maintenance free operation.

WORKS WITH SMARTPHONES AND EFENTO GATEWAY

Data from Efento Bluetooth Low Energy sensors can be read by smartphone with free mobile application or Efento Gateway. Depending on the use case (online monitoring or data logging), you will find a solution that suits you

YEARS OF MAINTENANCE FREE OPERATIONS

Large capacity battery ensures five years of maintenance free operation. Efento Bluetooth Low Energy sensors use standard batteries, which can be replaced by the user

DATA SECURITY

Communication between Efento sensors and mobile applications or Efento Cloud can be encrypted (AES128), so only the authorized devices can get the measurements

LONG RANGE

Sensor’s range is 100 meters in open space and 30 meters in buildings

LARGE MEMORY

Efento BLE sensor stores 60 000 measurements in its memory. This allows you to keep the measurements from a few months in device’s memory and read it in a convenient moment. Moreover, if your sensor lost the connection with Efento Gateway for a while, after re-establishing it, it will send the missing data

How does it work?

Efento Cloud

Wireless sensors that work with any platform

Taking measurements is just the beginning. IoT solutions must have a backend platform which analyses them. Efento wireless sensors can work out of the box with Efento Cloud and two mobile applications. On top of that, you can easily integrate them with your own mobile applications or with any Bluetooth Low Energy compatible device.

1

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 Bluetooth Low energy sensors can be integrated with any BLE enabled device. To make the integration easy, we can provide you with the BLE communication documentation or Android SDK which will speed up the development process. Moreover, you can integrate Efento Gateway directly to your cloud solution and receive the data over well known and widely supported REST.

EFENTO TRANSPORT

Efento Transport is a solution for monitoring of the temperature of goods during transportation. Efento sensors send the data to a smartphone with a mobile application which allows drivers to constantly monitor the temperature and generate reports from deliveries. Efento Transport can be integrated with Transport Management Systems. Learn more about Efento Transport.

EFENTO INSPECTOR

Efento Inspector is a solution dedicated to small clinics. It is used to constantly monitor the temperature of medical refrigerators, generate reports and send SMS / email notifications when the safe range is exceeded. Learn more about Efento Inspector.

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 an additional fee, we can provide you with a calibration certificate issued by a certified laboratory. Learn more about the calibration service.

Quickly deploy hundreds of sensors

We know that deploying thousands of IoT devices may be frustrating and time consuming. That’s why we designed Efento wireless sensors and Gateway in a way to make the deployment proces 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

QUICK CONFIGURATION

Connect Efento Gateway to your network and configure it with a mobile application over Bluetooth Low Energy. Once it’s configured, all the sensors in its range will automatically show up on your Efento Cloud account

NO MORE WIRES

Efento sensors communicate with Efento Gateway wirelessly and all configuration can be done with a mobile application. Forget about connecting wires or configuring sensors with you laptop.

Secure over the air updates and device management

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 Efento Gateways and change their configuration.

FIRMWARE OVER THE AIR UPDATE

Efento Gateways firmware can be remotely updated. The whole communication between the server and the devices 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. The Sensor’s firmware can be updated over Bluetooth Low Energy interface.

DEVICES MANAGEMENT

We know that when you deploy a large number of IoT devices remote device management is a must. The whole management of your wireless sensors and gateways is done from Efento Cloud.
