Helmet Sensors Alert Users Of Carbon Monoxide Poisoning
Gasoline powered tools used at construction site emit carbon monoxide, and in enclosed construction setups, they may cause poisoning. In order to solve this problem, students at Virginia Tech have developed a sensor that can alert the users of the increased blood gas saturation levels so that corrective actions can be taken. The sensor mounts on the helmet and does not interfere in the operations or movements of the user. The students who've developed the sensors explained how they integrated a pulse oximetry sensor into a helmet.
In their demonstration, which was performed without exposing the workers to dangerous CO levels, the researchers monitored blood oxygen saturation. Monitoring oxygen levels and CO levels differs only in the number of wavelengths of light employed. The researchers are confident that their sensors can accurately measure required parameters and alert the users well in time.
The team says that mounting the sensors on the helmet is just the first step in realising a long-term vision of creating a network of wearable and environmental sensors & protective gear at the construction sites. The approach is designed to improve the safety of the workers. The details of the research are available on the source link.
