Block Diagram - Fertility Monitor
PSoC programmable analog & digital resources integrate everything shown in light blue below. Click on the colored blocks to view or sample the recommended PSoC Components.

 

The flexibility of PSoC allows you to customize each colored block, or PSoC Component, to meet your design requirements through the easy-to-use PSoC Creator Software IDE.  These Components are available as pre-built, pre-characterized IP elements in PSoC Creator.


Design Considerations
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.
PSoC® 3 and PSoC 5 provide a scalable platform which provides all the requisite circuitry to provide a configurable Fertility Monitor on Chip, including:

  •  High precision Analog front end, including a 0.1% accurate Voltage reference and up to 20 bits of resolution
  •  Circuitry for sequencing and driving LED for optical measurement of the test strip and the circuitry for reading the photodiode to create a full optical measurement system
  •  LCD direct drive and control
  •  Low active and sleep mode power consumption, with full operation down to 0.5V
  •  CapSense fully integrated
  •  FS USB
  •  On chip EEPROM


Application Notes

AN52927 - PSoC® 3 and PSoC 5LP - Segment LCD Direct Drive
Although segment LCD modules are available with inbuilt drivers, these modules are more expensive than segment LCD glass. PSoC® 3 and PSoC 5 LP, with its configurable analog and digital hardware, also has an integrated configurable LCD driver that supports a wide variety of LCD glass types. This application note explains how to drive multiplexed segment LCD glass using PSoC 3 and PSoC 5LP.
