Oizom Odosense - Odour Monitoring System

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

Odosense measures odourful parameters like 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 is technologically equipped to offer higher accuracy with features like patented e-breathing technology, Auto device firmware updates, and remote calibration capabilities. Additionally, our systems are backed with AI ML algorithms to understand odour levels and impact.

Odosense, our accurate odour monitor can transmit data through various data communication modules like GSM, WiFi, LORA, etc. The data is transmitted 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. The collected data can be visualized on the Oizom IoT Terminal in the form of real-time dashboards, upon collection on a dense network of data points and integrating weather data we can also generate odour plumes and odour dispersion heatmaps. By integrating data from the Odosense onto 3rd party odour modelling platforms we can enable advanced analytics on the odour levels. The odour data can also be utilised for various industrial automation applications in an Industrial IoT (IIoT) environment.

Our sensing technology works on proven working principles like NDIR, PID, Electrochemical Analysis, Semiconductor, Optical Measurement. As a part of our proprietary ‘Micro Active Sampling’ (e-breathing technology), we have a sophisticated suction-and-exhaust system for air sample collection and monitoring inside a controlled environment. This isolates the effect of external environment on measurement to achieve 13% higher accuracy than the industry standards.

Electrochemical Analysis – The gaseous emission is treated electrochemically, where an external potential is applied. Each species like CO2, H2S, CH4, etc. is identified depending on their oxidation or reduction potential.

NDIR – The gases emitted from the location undergo Nondispersive Infrared Radiation where the sample air is subjected to infrared radiation. Different gaseous molecules absorb IR at different frequencies. The amount of IR absorbed gives the volumetric concentration of each gaseous constituent.

PID – Photoionization detection method is used to quantify TVOCs present in the sample. Highly energized UV photons bombard the molecules, which ionize and make them positively charged. These ionized molecules, in return, produce an electric current which gives a volumetric concentration of the molecules. The higher the current generated, the higher is the gaseous concentration in the sample.

Odosense Solution is designed with an ultra-modular approach to accommodate 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 odour data monitored by Odosense can be transmitted to Oizom Cloud which can be hosted on Shared or Private Infrastructure. The data from Oizom Cloud can be served for different data-solutions based on end-application.

Odosense data can be visualised and analysed in Oizom Data Terminal. Smart odour alerts can be set-up on the odour data from Odosense. Various process equipment can be regulated based on Odosense data for automated solutions. Automated reports can be generated by the system. Using Odosense data, realtime odour impact assessment is possible for effective odour complaint management.
