85C1-UA DC 0-100uA Analog Panel Meter Ammeter Gauge

Description

What it is

The Amperometer Gauge 85C1-UA DC 0-100uA is an electronic measurement device designed to monitor small DC currents. This analog ammeter provides a visual readout of electric current from 0 to 100 microamperes.

Features

• DC current measurement from 0 to 100µA
• Analog format for direct and intuitive visualization

What it is for

The ammeter is ideal for projects requiring the monitoring of low-level electric currents. It can be used in conjunction with Arduino or other microcontrollers like ESP8266/ESP32 to create alarm or automatic current monitoring systems.

Tutorial: How to use Analog Ammeter 85C1-UA

The analog ammeter 85C1-UA is a useful device for monitoring electric currents from 0 to 100µA. Ideal for low current measurement projects.

What you need

• Arduino Uno or compatible
• dupont connectors
• USB cable

Steps

1. Connect the red connector (+) to the VCC pin of the Arduino.
2. Connect the black connector (-) to the GND pin of the Arduino.
3. Check the datasheet to connect the control signals to the appropriate pins of the Arduino.
4. Install the required library if requested by the product manual.
5. Write the Arduino sketch that reads the current value and displays it on a display or via Serial Monitor.

Example code

// Codice di esempio
void setup() {
  Serial.begin(9600);
}
void loop() {
  int current = analogRead(A0); // Verifica sul datasheet per il pin corretto
  float voltage = current * (5.0 / 1024.0);
  float amperage = voltage / 100; // Verifica la resistenza di sensore specifica del prodotto
  Serial.print("Corrente: ");
  Serial.println(amperage);
}

Mini project

Create an alarm system that activates a siren when the electrical current exceeds a certain limit.

Common mistakes

• Connect the VCC pin to GND.
• Do not verify the signal values on the datasheet.
• Use a power supply voltage that does not conform to the product specifications.

Recommended accessories

• Current measuring resistor (SKU: ARD012345)
• Arduino Uno (SKU: ARD098765)
• USB Micro B cable (SKU: ARD043210)

Frequently asked questions
