Bluetooth Low Energy

Wireless hydrogen sulfide (H2S) logger

Wireless hydrogen sulfide (H2S) logger measures and transmit gas concentration over Bluetooth Low Energy. On top of the the concentration, the sensor measures also 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: 0-100 ppm
  • 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 40,000 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

Efento x IoT Creators.
Efento NB-IoT sensors have been successfully integrated with Deutsche Telekom’s platform iotcreators.com. How does it work? Set up an account at iotcreators.com -> Get a SIM card -> configure Efento sensor -> receive sensor’s messages to your server over REST.
New battery life time tool and protocol tool.
We have recently deployed a new set of tools that allow you to simulate the battery life time of Efento NB-IoT sensors depending on their settings and encode/decode protobuf messages sent by the sensors.
Efento on GitHub.
We have launched a GitHub profile, which contains code examples, tutorials on how to integrate Efento’s products into your solutions and useful tools. We will be regularly adding new tools and examples, so don’t forget to follow us!
“How warm is the water?”
This is one of the most common questions you can hear during Swedish summer. Learn how the municipality of Lerum, Sweden uses NB-IoT sensors to monitor and publish on the website current temperatures of water in the lakes.
Efento IoT Academy: BLE sensors integration.
Is it possible to integrate IoT sensors into your solution in less than 60 lines of code?
