Monitoring Tensi Suhu BPM SUHU IOT Thingspeak

Monitoring Tensi BPM SUHU IOT Thingspeak

 

        Pada kesempatan kali ini saya akan menjelaskan mengenai bagaimana cara membuat sebuah alat yang dapat mengukur tensi, suhu, Bpm, dengan menggunakan iot thingspeak, sensor yang dipakai yaitu mpx5050dp dan max30100, sensor suhu ds18b20. untuk lebih jelasnya beikut adalah koding dan komponennya.
