In an example, a system includes a light source, a photodetector, and a processor. The processor obtains a first measurement of ambient light received from the photodetector while the light source is off. The processor causes the light source to transmit light. The processor obtains a second measurement from the photodetector during the transmission, the second measurement including the ambient light and the pulsed light reflected from an object. The processor determines a color of the color changing indicator by removing an ambient light signal from the second measurement based on the first measurement and therefrom determines a volume of bodily exudate present."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Color sensing using pulsed light","description":"Techniques for detecting a color of a color changing indicator in the presence of ambient light.
