Voltage Current Monitoring adalah projek untuk memaparkan voltan, arus dan suhu. Bacaan voltan menggunakan voltage divider, bacaan arus menggunakan sensor ACS712 dan bacaan suhu menggunakan sensor DS18B20. Paparannnya menggunakan LCD 20X4.
Skematiknya adalah seperti berikut.
PCB komponen layout nya adalah seperti berikut.

Dear Sir
Is it possible to have a copy of the PIC code for this great project?
I have been looking for this type of unit as I wish to monitor the voltage and current in my home built amateur radio
RF amplifier
Kind Regards
Keith
Not for free.
Salam bro. Tumpang tnya, projek ni ada termasuk visual & audio ke? Dan boleh tnya brapa kos projek ni yer?
w/salam, harga dah tulis kat atas. Projek ni tiada visual & audio, yg tu kena design lain.
Salam bro,nak tanya sikit,kami mempunyai projek akhir iaitu phone charger alarm dan cutoff suis.Apabila bateri telefon sudah penuh buzzer akan bebunyi.adakah masuk akal untuk menjalankan projek ini berdasarkan current yg brubah ketika mengecas iaitu bila cas penuh current berhenti..kerjasama tuan amat dihargai.
W/salam, boleh buat.
