5.4.7. Harmful Gas Detection System [Noida]

Real Time Monitoring System for Detection of harmful gases consists of distributed
gas sensing nodes that monitors the safety levels of targeted gas leakage in the
deployed environment and transmits the safety status over an RF network to Control
Station.

Each of the individual nodes is equipped with a gas sensor to detect leakage of
targeted gas. Each of the sensing nodes is calibrated to raise alarm much before
leakage concentration of targeted gas reaches unsafe levels. The gas concentration
levels are analysed and packetized and an RF transceiver transmits these packets to
the Central Coordinator. The Central Coordinator is connected to a control station
that monitors the safety status send by each node.

In case of leakage, control station raises an audio and visual alarm informing the
operator about the leakage and the node location. Nodes can generate Audio and
visual alerts.

5.4.8. Obnoxious Odour Measurement System [Kolkata]

Obnoxious Odour Measurement Device is an instrument that can measure
concentration of odorants like Dimethyl Sulfide, Dimethyl Disulfide, Hydrogen Sulfide
and Methyl Mercaptan and displays Obnoxious Odour Index, Odour Concentration
and Odour Intensity. This instrument is suitable in Tannery, Distillery, Pulp and paper
Industries, Gas manufacturing industries and Sewage water treatment.
