Sometimes, women find it difficult to conceive a baby and others use contraceptives that often have side effects. Researchers have already established the importance of measuring basal body temperature (BBT) and the potential of hydrogen (pH).
We have designed and realized a device that allows the simultaneous measurement of the BBT and the pH. We used an Arduino Uno board, a pH sensor, and a temperature sensor. The device communicates with a smartphone, can be integrated into all e-health platforms, and can be used at home. We validated our ovulation detector by a measurement campaign on a group of twenty women. If the pH is >7 and at the same time, the BBT is minimum and <36.5°C, the women is in ovulation phase. If the pH is ≤7 and in the same time, the BBT is between 36.5°C and 37°C, the women are in preovulation or follicular phase. If the pH is ≤7 and in the same time, the BBT is >36.5°C, the women are in postovulation or luteal phase.
We tested the contraceptive aspect of our ovulometer on a set of seven women. We also tested the help of conceiving babies by having intercourse during the ovulation period fixed by our ovulation detector. The results are satisfactory.
In the final version of our device, we displayed just in "fertility period" if the pH is ≥7 and the BBT is <36.5°C else we displayed in "nonfertility period."
有时，女性难以受孕，而其他人使用的避孕药往往有副作用。研究人员已经确定了测量基础体温（BBT）的重要性以及酸碱度（pH）的潜在作用。
我们设计并实现了一种能够同时测量基础体温和酸碱度的设备。我们使用了一块Arduino Uno板、一个pH传感器和一个温度传感器。该设备与智能手机通信，可集成到所有电子健康平台中，并且可以在家中使用。我们通过对一组20名女性进行测量活动来验证我们的排卵检测器。如果pH值>7，同时基础体温最低且<36.5°C，则女性处于排卵期。如果pH值≤7，同时基础体温在36.5°C至37°C之间，则女性处于排卵前或卵泡期。如果pH值≤7，同时基础体温>36.5°C，则女性处于排卵后或黄体期。
我们在一组7名女性身上测试了我们的排卵计的避孕效果。我们还通过在我们的排卵检测器确定的排卵期进行性交来测试其对受孕的帮助。结果令人满意。
在我们设备的最终版本中，如果pH值≥7且基础体温<36.5°C，我们仅显示“生育期”，否则显示“非生育期”。
