Odosense Odor Monitoring System


Odosense is an e-nose based odor monitoring system designed to monitor various odorful and toxic gases. Odosense continuously detects, measures, and monitors the odorful gaseous contaminants. Oizom Odor Monitoring Solution comprises a network of e-noses (OdosenseTM) positioned on the periphery of the site. One can also monitor meteorological parameters like wind speed, wind direction by using external modules. The weather modules enable us to trace the odorant dispersion plume and identify odor source.

Odor monitoring around landfill sites, wastewater treatment facilities, fertilizers, paper-pulp industries, and soil-treatment sites, etc. is very crucial as they usually create odor nuisance and could be a health hazard for the employees and residents living in the surrounding areas. Hence, odor monitoring can act as an alarm system in cases of accidental releases of pollutants; through odor plume dispersion we can also backtrack the source of the odor. So, it is essential to keep a track of odor intensity to take suggestive actions like planning odor mitigation activities. Additionally, in the case of false complaints, the authorities have the data for reference purposes.

Odosense measures odorful parameters such as Sulfur Dioxide (SO2), Hydrogen sulphide (H2S), Ammonia (NH3), Methyl Mercaptan, TVOC (Benzene, Toluene, Xylene), Formaldehyde (CH2O), Nitrogen Dioxide (NO2), Chlorine (CL2), Temperature and Humidity.
The Odosense technologically provides better accuracy with features including unique e-breathing technology, auto device firmware upgrades, and remote calibration capabilities. Our systems also use AI and machine learning algorithms to understand smell levels and impact.

Odosense, our accurate odor monitor can transmit data through various data communication modules like GSM, WiFi, LORA, etc. Simultaneously, the data is transferable to the Oizom cloud in near real-time. Additionally, it has an inbuilt memory backup to ensure no data loss in case of network failure. This ensures the best device uptime. Uses can visualize the collected data on the Oizom IoT Terminal in the form of real-time dashboards. Users can also generate odor plumes and odor dispersion heatmaps upon a dense network of data points and weather data integration. Hence, by integrating data from the Odosense onto 3rd party odor modeling platforms we can enable advanced analytics on the odor levels. The odor data can also be useful for various industrial automation applications in an Industrial IoT (IIoT) environment.


The Odosense can be configured to sense multiple parameters.  The following is a partial list.

  • Sulfur Dioxide (SO2)
  • Hydrogen sulfide (H2S)
  • Ammonia (NH3)
  • Methyl Mercaptan (CH3SH)
  • TVOC (Benzene, Toluene, Xylene)
  • Formaldehyde (CH2O)
  • Nitrogen Dioxide (NO2)
  • Chlorine (CL2)
  • Ambient Light and UV Radiation
  • Temperature and Humidity

System Architecture

Odosense Odor Monitoring System

Odosense Solution is an ultra-modular odor monitoring system, that accommodates in any existing infrastructure. For power, Odosense can work on External AC or DC power as well as Solar Power. For data transmission, Odosense can communicate the data using various Wired and Wireless channels. GSM, GPRS, 3G, WiFi, LORA, LTE, SIGFOX are available for wireless data communication. Where Ethernet, Modbus, RS-485, RS-283 are the wired data-communication options. The odor data monitored by Odosense can be transmitted to Oizom Cloud which can be hosted on Shared or Private Infrastructure. Additionally, the data from Oizom Cloud can be useful for different data solutions on the basis of the end application.

Visualisation and analysis of Odosense data is possible in Oizom Data Terminal. Smart odor alerts can be set up on the odor data from Odosense. Various process equipment can be regulated based on Odosense data for automated solutions. Successively, automated reports can be generated by the system. Using Odosense data, real-time odor impact assessment is possible for effective odor complaint management.
