Cypress CY8C38系列怀孕监视器PSoC开发方案

怀孕监视器采用监测荷尔蒙水平来实现, 荷尔蒙水平监测由三种标准方法:尿液, 唾液和体温.每种检测需要模拟前端来实现.本文介绍了采用Cypress公司的CY8C38系列来开发怀孕监视器的确具体方案,方框图以及CY8C38 系列特性,框图,CY8C38系列典型应用电路图以及CY8CKIT-001 PSoC开发板主要特性,电路图和材料清单.

Fertility Monitors are devices that monitor fertility levels by monitoring hormone levels. A fertility monitor may analyze hormone levels in bodily fluids, resistance in bodily fluids, basal temperature, or a combination of these methods. There are three standard methods for monitoring hormone levels:

Urine: Tests for luteinizing hormone surge

Saliva: Detects changing electrolyte levels

Temperature: Monitors basal body temperature to predict cycles

Each of these sensing methods require an analog front end (AFE) to perform the necessary measurements. Fertility Monitors are battery powered devices so active power consumption and sleep current are important considerations. A fertility monitor also includes a display, memory for storage of fertility reading history, serial communication such as USB. A touchscreen or capsense user interface may also be seen in fertility monitors.
