Wireless ozone (O3) logger measures and transmit gas concentration over Bluetooth Low Energy. In addition to gas concentration, the sensor also measures temperature and humidity. 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 for objects which need supervision such as smart cities, public buildings, workshops, assembly halls, industrial companies, etc.
Range: 0-4 ppm (4 000 ppb)
Temperature: -35 to +70°C, accuracy: up to 0.4°C in the range from -20°C to +70°C and up to 0.5°C in the range -35 to -20°C
Humidity: 0 to 100% RH, accuracy 4% in the range of 0 to 80% and 7% in the range of 81 to 99%
Measurement period: 1 minute – 10 days (configurable by the user)
The device stores 60,000 measurements in its memory, when the memory is full, the oldest measurements are overwritten
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
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.
Gas sensors calibration
The gas sensors are pre-calibrated at the factory. If needed, user can independently calibrate the device using mobile application and a gas tank with a known gas concentration. The user places the gas sensor near the tank with a known gas concentration and specifies the concentration level using a free mobile application, the sensor measures the concentration and corrects the parameters based on the concentration of the gas in the tank.
Data security
Data transmitted wirelessly between the sensor and smartphone/Efento Gateway 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.
