Computation-led design of pollutant gas sensors with bare ...

· Abstract Quantum chemical study has been performed on finite-sized bi-metallic Rh3M alloys, M = Ag, Ir, Pd, Pt, Au, derived from magic cluster, Rh4. Bond length of C–O and N–O are noticed to be elongated in the presence of rhodium alloy clusters. CO2 and NO2 gases are found to be highly adsorbed on Rh3M clusters, which is confirmed by stretching frequency of C–O and N–O. DFT …

Particle Detection Via Optical Sensors

Figure 2. Optical sensing can bring intelligence to smoke detectors by tapping into PPG sensors, such as the MAX30101, for particle sensing. To overcome these complexities, engineers have addressed some particle-sensing problems empirically. By interrogating the same suspension of particles with lights of different wavelengths, it is possible ...

Gas Sensor - Arduino Project Hub

· This gas sensor uses a MQ-2 gas sensor to indicate if there is gas in the area. so the sensor has a threshold value (the threshold value is around the amount of smoke in there is a fire) in that if it goes above it starts alerting people in the vicinity. The alert just shows a red led and starts beeping. This idea is very helpful and is used on a daily basis with the smoke alarms that a lot of ...
