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.
You can use a free mobile application to configure the device and read the data from its memory. If you add Efento Gateway, you can build a remote monitoring system.
- PIR motion detection: 40° × 105° field of view with a detection range of up to 12 m for human-sized objects
- Configurable occupancy detection: Detects every movement individually or determines room occupancy based on a configurable number of movements within a defined time period
- Battery ensures up to 5 years of maintenance-free operation
- Add Efento Gateway and Efento Cloud to build a real time monitoring system. The maximum distance between the sensor and the Gateway is 100 m in the open space and 20 – 30 m in the buildings
- Use a free mobile application to configure the logger, read the data from its memory, generate reports and set alert thresholds
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.Flexible motion and occupancy detection
The device can operate as a standard motion sensor, detecting each movement individually, or as an occupancy sensor by counting movements within configurable time intervals. This allows the system to determine whether a room is occupied based on user-defined rules. Measurement data can be stored in the device memory and transmitted to the server at scheduled intervals, or sent immediately whenever the sensor state changes, such as when motion is detected or room occupancy is confirmed.Large detection zone
The PIR sensor offers a 40° × 105° field of view and detects human-sized objects at distances of up to 12 m under standard conditions. With a larger temperature difference between the object and the environment, the detection range can increase to up to 17 m. The sensor is designed for wall or corner mounting, allowing it to cover large areas of a room efficiently.
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.Sensor’s passport
Sensor’s passport documents the entire lifecycle of a device. By accessing the data on Efento Cloud platform, the user can check all information about the sensor: date of sale, warranty status, date of calibration, information on all service activities. In addition, the user can download all documents regarding the device – a duplicate of calibration certificate or service protocols.

Efento Cloud for hospitals – safety, savings and full control
A hospital consists of thousands of processes, devices, and rooms whose proper functioning is essential for patient safety. One of these is ensuring proper storage conditions for medicines, vaccines, medical supplies, and laboratory samples.Efento devices can also monitor gas and liquid pressure, water leaks, and visitor footfall.
Efento Cloud enables automated monitoring and control.
Automated pressure warning systems
Pressure sensors are installed in water, oil, chemical, or compressed air pipelines for continuous pressure monitoring. In the event of a pressure issue, a PLC controller operates a pump or valve to immediately increase or decrease the pressure. However, most pressure sensors only provide control signals and lack alerting capabilities.Is it necessary to archive reports from the Efento system?
Data from temperature loggers used in the storage and transport of vaccines must be kept for at least 5 years. In the case of the Efento system, measurement data from the loggers is stored for 6 years. To ensure that nothing is lost (e.g., due to a failure), it is simultaneously saved in two independent data centers (AWS servers).We were busy deploying 150,000 NB-IoT sensors – The Things Conference
The 9th edition of The Things Conference—the premier global IoT event held on September 22–23, 2026, in Amsterdam—brought together over 2,500 experts from around the world.We are proud to have been a Bronze Partner of this conference.
