Summary of PIC16F84 AMMETER CIRCUIT 0-80A UGN3503
This project describes a PIC16F84-based automotive ammeter capable of measuring current up to 80A. It utilizes a UGN3503 Hall effect sensor and an LM358 operational amplifier to process signals, which are then displayed on an LTS542R LED module. The device features a 2-digit display with 1A resolution, a bar graph indicator, and automatic screen dimming for low-light conditions, offering precise monitoring of battery charge and discharge rates compared to standard vehicle warning lights.

- PIC16F84 microcontroller
- UGN3503 Hall effect sensor
- LM358 operational amplifier
- LTS542R LED display
- 7-segment LEDs

It’s now rare to see an amp meter installed in a car. Instead, virtually all modern cars have an “idiot” light to indicate battery charging. Normally, this light is off when the engine is running and only comes on if the alternator fails; ie, when no charge is being delivered. Apart from that, it doesn’t provide any other information during normal driving. This means that when the light is out, you have no idea how much current is going into the battery or is being pulled out. And even when an ammeter was fitted, it was hardly what you would call a precision instrument. Most only gave a very rough idea of what happening. However, if you are an enthusiast, you will want to know more about battery charge and discharge rates. This Automotive Ammeter can provide this information with a high degree of accuracy.
