Prototype of our Thermistor Respiratory Monitor

Thermistor Respiratory Monitor

The concluding assignment in ECE 4760 involves the creation of a respiratory monitor tailored for use in resource-constrained settings. This device determines a patient’s respiration rate by identifying temperature fluctuations as the patient breathes through a mask. Notable attributes of this device encompass an alarm mechanism activated by a piezoelectric speaker, which triggers when the […]

Temperature to period circuit provides linearization of thermistor response

Temperature-to-period circuit provides linearization of thermistor response

Designers often use thermistors rather than other temperature sensors because thermistors offer high sensitivity, compactness, low cost, and small time constants. But most thermistors’ resistance-versus-temperature characteristics are highly nonlinear and need correction for applications that require a linear response. Using a thermistor as a sensor, the simple circuit in Figure 1 provides a time period varying linearly
