NB-IoT
Motion / occupancy sensor
Motion sensor detects movements based on a PIR sensor. Depending on the configuration, the sensors can be used to detect any movements (e.g. unauthorised access to restricted areas) or monitor room occupancy (conference rooms, shared spaces, etc.). Based on this data, users can get insights on office spaces utilisation.
Efento NB-IoT sensors transmit the data over cellular network (Narrowband IoT) and do not require any additional devices (router, gateway, etc.). Sensors are also equipped with Bluetooth Low Energy interface, which allows quick and easy configuration with a smartphone. Efento NB-IoT sensors can be integrated with any cloud platform.
- PIR sensor with 40°×105° field of view detects movements of human size objects in the distance of 0-12 meters from the device
- User can configure the device to detect every single movement or set the number of movements in a time period required to detect the room occupancy
- Battery ensures up to 5 years of maintenance-free operation
- NB-IoT sensors send the data over the cellular network to Efento Cloud or any other cloud platform.
- Sensor's configuration can be changed remotely from the cloud or with a mobile application over Bluetooth Low Energy
Key features
Efento Cloud
Together with Efento Cloud, the sensors enable constant monitoring, alerting about exceeding safe limits, generating reports and analyzes.
Long battery life
Loggers have been designed to work for up to 10 years on batteries. You do not have to remember about changing the batteries frequently or troublesome batteries charging.
Lower costs
Choosing wireless sensors and a cloud platform reduces the installation and maintenance costs.
Wide range of sensors
Efento sensors can measure various physical and chemical values. If you decide on one sensor today, you can expand your sensors fleet to another types anytime you want.
Integration
Standard communication protocols allow integration with any cloud platform or mobile application.
Easy set up
All you need to set up a logger is a smartphone with a free mobile application. The whole configuration takes no more than 15 minutes.Motion / occupancy detection
User can configure the device to detect every single movement (act as a regular motion sensor used in alarm systems) or count the number of detected movements in the set time periods in order to detect the room occupancy (e.g. if the sensor detected 10 movements in 5 consecutive 1 minute periods, the room is occupied). The device can store the data in its memory and send it to the server on the set transmission intervals or send the data to the server on each change of state (movement detected / room is occupied)Large detection zone
PIR sensor with 40°×105° field of view detects movements of human size objects in the distance of 0-12 meters from the device. The device is designed to be mounted on walls, in the rooms corners and cover the whole rooms areas.
Software over the air update (SOTA)
The sensors are equipped with over the air software update mechanism, thanks to which, your fleet of sensors will always have the latest version of software. Moreover, SOTA is based on delta mechanism and only the difference between the current and the new version of the software is sent to the device. This saves both the battery and data transfer.
Full remote configuration
All the settings of the NB-IoT sensors can be changed remotely in a secure way. This allows you to easily reconfigure thousands of the deployed devices, no matter how far they are located.Integration
We believe that the Internet of Things is about integrating data sources, analysing the data and drawing conclusions based on it. If you want to integrate Efento loggers with your software, cloud platform or mobile application, we will provide you with the necessary documentation, libraries, SDKs and we will gladly assist you.
