Bluetooth Low Energy
Wireless carbon dioxide CO2 logger
Efento wireless carbon dioxide (CO2) logger measures gas concentration and transmit its values over Bluetooth Low Energy. On top of the gas concentration, the logger also measures temperature, humidity and barometric pressure.
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.
- CO2: 400 ppm – 5000 ppm, accuracy ±(40 ppm + 5 % of reading)
- 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%
- Pressure: 300 to 1100 hPa, absolute accuracy +/- 3 hPa at 0 to + 65°C, relative +/- 0.12 hPa at 0 to + 65°C, p = 800 - 900 hPa
- Battery ensures up to 5 years of maintenance-free operation
- Measurement period: 1 minute – 10 days (configurable by the user)
- User configurable alarm thresholds. If any of the thresholds is exceeded, sensor will send the data to the platform immediately
- The device stores 40,000 measurements in its memory, when the memory is full, the oldest measurements are overwritten
- 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.Automatic CO2 sensor calibration
Logger automatically calibrates the CO2 sensor based on the barometric pressure sensor and the concentration of CO2 in the atmosphereData 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.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.
