The current output of the sensor is coupled to a sample and hold capacitor for a precision time period thereby charging the sample and hold capacitor to a voltage proportional to current provided by the sensor over the precision time period. The voltage on the sample and hold capacitor is converted to a digital representation and a determination is made whether the external condition represents an alarm situation, e.g., smoke detected from a fire."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Current sensing with internal ADC capacitor","description":"External conditions, e.g., smoke, temperature, humidity, humidity, pressure, flow rate, etc., affects a sensor's characteristics, wherein the sensor provides a current output representative of its cha","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9823280","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
