ทำเรื่องแจ้งเตือนเมื่อ bpm สูงกว่า 120 ค่ะ pulse sensor ที่ใช้คือ MAX30100 ค่ะ upload ลง esp8266 สำเร็จ หากค่า bpm ต่ำกว่า 120 sensor ทำงานปกติหมดทุกตัวค่ะ แต่เมื่อค่า bpm สูงกว่า 120 แจ้งเตือนไลน์รับค่าที่เกิน 120 มาได้ 1 ค่าแล้วค้างค่านั้นตลอดเลยค่ะ Line Notify เด้งค่านั้นตลอด ที่ OLED ก็ค้างเช่นกันค่ะ
