NB-IoT
Wireless indoor air quality, temperature and humidity logger
Wireless temperature, humidity and air quality logger is designed to monitor indoor climate conditions. The device measures air quality based on the concentration of volatile organic compounds (VOC) and calculates IAQ (Indoor Air Quality) representing air quality in the room based on the Bosch patented algorithm. Volatile organic compounds are substances derived from many indoor products, including from paints, cleaning agents, solvents, alcohol or glue. Some volatile organic compounds are carcinogenic. In addition, the sensor measures the temperature and relative humidity of air, which, in combination with the VOC concentration, gives a full picture of the room conditions.
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.
- Air quality: 0-500 IAQ 0-50 - Good 51-100 - Average 101-150 - Little bad 151-200 - Bad 301-500 - Worse 500+ Very bad
- Temperature: -15 to +70°C, accuracy: up to 0.4°C
- Humidity: 0 to 99% RH, accuracy up to 4% in the range of 0 to 80%
- Measurement period: 1 minute – 10 days (configurable by the user)
- The device stores 40,000 measurements in its memory, when the memory is full, the oldest measurements are overwritten
- Use a free mobile application to configure the logger, read the data from its memory, generate reports and set alert thresholds
- 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.
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 5 years on battery. You can forget about changing the battery frequently or troublesome battery 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.Calibration certificate
At the customer’s request, each Efento sensor can be supplied with a calibration certificate in accordance with ISO / IEC 17025. The test is performed in an external, ILAC certified laboratory.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.Data security
Data transmitted wirelessly can be encrypted. Thanks to that, unauthorized persons cannot hijack the communication between sensors and other devices. Efento sensors' software can be updated over the air, which will allow you to easily install any security patch that is released.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.Measures Indoor Air Quality
