A field demonstration of nanomaterial-modified Laser-Induced Graphene (LIG) based electrodes for gas sensing was conducted in the Chikkaballapur District Municipality. This initiative, in collaboration with ICMR-NIOH-ROHCS Bangalore, aimed to assess the real-time air quality monitoring at sewage dump and manhole on municipality canal. The integration of nanomaterials enhanced sensor sensitivity and selectivity, enabling precise detection of hazardous gases for the safety of Safai Karmacharis. The project marks a significant step toward deploying cost-effective, scalable gas sensing technologies for public health surveillance and environmental monitoring.
