Oizom - State of Art Technology in Environmental Monitoring
From Other Products
Oizom has years of experience in stimulating innovation by creating groundbreaking technology for environmental monitoring. With IoT-based development approach, Oizom has been able to successfully unlock multiple solutions, catering to various industries. Our sensing technology works on proven working principles like NDIR, Electrochemical Analysis, Semiconductor, Optical Measurement, and Laser-Scattering. As a part of our proprietary ‘Micro Active Sampling’ (e-breathing technology), we have a smartly-designed sample intake and monitoring system inside a controlled environment. This isolates the effect of external environment on measurement to achieve 13% higher accuracy than the industry standards.

Accuracy through Multi-level Calibration
All the sensors are calibrated at Oizom factory before dispatching the equipment to check their functioning. It is basically a Bump Test performed to verify that the sensor is working properly for each parameter. All the parameters which the equipment is capable of monitoring like particulate concentration gaseous contaminants, noise, odour, temperature, humidity, pressure, light intensity, etc. are tested here.
Oizom equipment are calibrated in the National Accreditation Board for Testing and Calibration Laboratories to ensure data accuracy and eliminate cross sensitivity among the sensors. Calibration is carried out for all the parameters like PM, noise, temperature, humidity, pressure, odour, UV radiations, etc. Gas calibration is done with pure air and calibration gas, at a high concentration range of 1-10 PPM and flow rate of 0.5L/min.
Through spot calibration, the equipment is calibrated over the cloud, reducing onsite manpower and maintenance cost. It is a periodic calibration performed quarterly or bi-annually depending on the air quality. Oizom uses a recently calibrated sensor-based system or a third-party system trusted by the client as a reference. The reference system should be a continuous monitoring system. Around 150 data points are collected at the same time-interval to re-calibrate a system on the spot.
Field Calibration (Co-Location)
Field Calibration (Co-Location)
The sensors are calibrated against a reference station before installation to test their performance in the ambient condition. These reference stations are generally situated near the target locations to calibrate under the required ambient conditions. Around 1000 data points collected at the same time interval is sufficient to calibrate the system. This is an optional calibration and depends on the customer’s requirement.
Low Power Electronics
All the sensors integrated within our equipment have a voltage usage of just 3.3-5V, thus achieving negligible consumption. The average power consumption is 0.6-2.4W (including all the accessories), meaning that the average electricity cost is less than 0.99$/month even if the device is online 24×7 all year round.
Data Encryption for Security
We have a very stringent data security policy. MQTT Protocol , REST APIs & OAuth 2.0 token-based encryption is implemented throughout the system. Oizom offers impenetrable data security by deploying SSL Encryption for Web Application.
Data acquired onsite is transmitted to the Oizom Terminal for analysis through our cloud platform. The results are then reverted to the users in desirable formats
Data can also be stored in the local server as per the customer’s requirements. Data is locally transferred using FTP to Terminal and final output is provided to the user.
