SL50, SCENTINAL

Compact Air Quality and odour Monitoring Station

SL50 Scentinal Compact Air Quality and odour Monitoring Station

Scentinal provides ambient odour emission monitoring based on high accuracy (ppb level) detection of odorous gases such as H2S, Ammonia, VOCs, and SO2. The flexible intelligent station allows live monitoring of plant emissions on Scentroid’s cloud servers. Odour emission is reported in OU/m3 based on correlation determined based on periodic measurements using field olfactometry.

Flexible Sensing and Modular Design

The Scentinal product is equipped with an H2S sensor, Photo Ionization Detector (PID), and an Ethyl sensor, however, additional sensing can be added at any time. Ammonia, SO2, NOx, VOC, TRS, PM2.5, PM10, and other chemical compounds can be monitored by adding additional optional modules. The system will allow up to 20 sensors to be optionally incorporated into one Scentinal Package. See the “Available sensors“ on this page for a list of close to 30 sensors that can be selected.

Self-Configuration for Plug and Play Installation

Each sensor node has a micro controller capable of recording the sensors exact GPS position. This position is sent to the central controller with each data transfer. At the time of the installation the technician simply needs to place the Scentinal unit and power it on. The central computer will automatically recognize the Scentinal unit and know of its exact location. To reconfigure the network the physical sensor can be moved and the system will learn and adapt to this change. Multiple Scentinal units can be configured within one monitoring area.

Time Synchronized Readings

When ambient H2S data or other chemical elements data is collected it is crucial to know exactly when the data was obtained. The entire sensor network must have a synchronized clock. The GPS chip is also used to sync the sensor`s clock to the GPS clock ensuring all recorded data has a perfectly synchronized time stamp. The Scentinal smart sensors are capable of storing data locally for up to 1 year. This data can be polled by the central station as required and if the system communication is lost then the system can recover without any data lost.

Correlation of Scentroid Chemical Element Measurements to Odour Units

Air Quality Monitoring Station

Correlation of Scentroid Chemical Element Measurements to Odour Units

Data from the Scentinal Compact Air Quality and odour Monitoring Station  system is processed by Scentroid’s chemical and olfactometric correlation system to determine odour impact in terms of odour units at the sensitive receptors. The Compact Air Quality and odour Monitoring Station uses a neural network learning algorithm to determine odour concentration from chemical readings.

Olfactometric measurements, using the Scentroid SM100 Field Olfactometer, are collected periodically (monthly, bi-monthly, or semi-annually) and are inputted into the learning algorithm along with recorded chemical composition. This sophisticated algorithm will then create a non-linear relationship between chemical readings and odour concentration. This data is used to teach the network and enhance the accuracy of odour concentration prediction from chemical composition. The advantage of this Compact Air Quality and odour Monitoring Station over other competing technologies such as E-Noses is that chemical to odour concentration is based on routinely gathered olfactometric data and therefore is always up to date regardless of changes to the plant processes.

Automatic Cleaning and Decontamination of All Lines

Scentinal Compact Air Quality and odour Monitoring Station

It has been reported that low level detection of pollutants in conventional e-noses and other monitoring stations in humid environments are prone to false positives due to contamination of the sampling lines including mold within the PTFE tubes and pumps. The Scentinal Compact Air Quality and odour Monitoring Station product has overcome this issue by installing a compact ozone generator in each monitoring station which is automatically activated once per day to clean and decontaminate all lines.

Local Data Storage and Smart Data Transfer

Local Data Storage and Smart Data Transfer

The Scentinal has a built in SD card that is used to store the collected data locally. While the system frequently sends the data to the central server, keeping a local copy ensures zero data loss even if there are communication issues. The rate of data transfer can also be configured through the central server to minimize GPRS traffic and to save on power.

What Scentinal package Included ?

Scentinal Includes:

  • Smart board for data processing and storage
  • GPRS pre-paid sim card
  • Monitoring software
  • Temperature and humidity sensors
  • Min of 3 to maximum of 20 Sensors
  • NEMA 4x Cabinet
  • Ozone generator which decontaminates all lines automatically once per day

Cloud Based Hosting

Cloud Based Hosting

The central monitoring station is hosted on a secure cloud based server allowing remote access via any internet based computer. The access is restricted and the data is encrypted for maximum security. Users are given a password and user name which will define their permission level. Operator access can simply view the results and create reports while administrator access can reconfigure the system and set all parameters.

The monitoring station is designed to collect all data from the sensors and present the sensor data in an easy to understand graphical interface.

Graphic Emission Representation and Reporting

Graphic Emission Representation and Reporting

The monitoring system continuously provides real-time readings of all sensors in the grid plus has the capability to show data for any defined instance in time. Furthermore reports such as specified period mean, high, low and variance for each sensor can be shown. Other reporting options such as sensor ranking in highest average reading and highest variation can also be requested.

Integration with Optional Total Odour Management System (TOMS)

Integration with Optional Total Odour Management System (TOMS)

The second stage of implementing a Scentinal sensing system is to input the data into Scentroid’s optional cloud based software TOMS. TOMS offers a complete, integrated suite for odour management. The system provides a perfect integration of real-time odour impact estimation with management of odour complaints from neighbouring residents. The simple to use software uses Scentinal sensory data, in field-olfactometry and live weather data to produce real time odour plumes showing you exactly the location and level of odour emissions. Neighbouring complaints are automatically logged and compared to odour emissions for fast and efficient validation.

FAQ

How many sensors can the Scentinal accommodate?

The Scentinal can accommodate up to 10 sensors by default and up to 20 sensors if requested.

Why does the Scentinal have a built-in ozone generator?

Mold and pollutants can built up on internal surfaces of other air quality monitoring station giving false readings especially at the ppb levels. Scentinal however automatically purges the entire system including the inlet filter and the sensor bays using pulses of ozone to decontaminate to unit. The intelligent Scentinal program will also record pre and post ozone sensor readings based on clean air to verify if decontamination was successful.

How many Scentinals can connect to the server?

There is no limit. You will  be provided with a login that will allow you to see all your Scentinal instruments simultaneously.

How often do I need to replace the sensors?

This depends on the type of sensors but ranges from 1 to 3 years. Sensors are inexpensive and the change is extremely easy taking no more than 15 min.
