Wiring Digital Inputs #

The digital inputs of NORVI AGENT 1-BT01-ES-N can be configured as both sink and source connections. The inverse of the Digital Input polarity should be supplied to the common terminal.

NORVI AGENT 1-BT01-ES-N Digital Input Wiring

Programming Digital Inputs #

Reading the relevant GPIO of the ESP32 gives the value of the Digital Input. When the inputs are in the OFF state, the GPIO goes HIGH, and when the input is in the ON stage, the GPIO goes LOW. Refer to the GPIO allocation table in the datasheet for the digital input GPIO.

#define INPUT1 18 
void setup() { 
   Serial.begin(115200); 
   Serial.println("Device Starting"); 

   pinMode(INPUT1, INPUT); 
} 
void loop() { 
   Serial.print(digitalRead(INPUT1));
   Serial.println(""); 
   delay(500); 
}

Analog Input #

Wiring Analog Inputs #

Reading Analog Input #

Reading the relevant I2C address of the ADC gives the value of the Analog Input.

Programming Analog Inputs #

#include <Adafruit_ADS1X15.h> 

#include <Wire.h> 

Adafruit_ADS1115 ads1; 

void setup() { 
   Serial.begin(115200); 
   Serial.println("Device Starting"); 

   Wire.begin(16,17); 
   ads1.begin(0x48); 
   ads1.setGain(GAIN_ONE); 
} 

void loop() { 
Serial.print("Analog 0 ");Serial.println(ads1.readADC_SingleEnded(0));  delay(10); 
Serial.print("Analog 1 ");Serial.println(ads1.readADC_SingleEnded(1)); delay(10); 
Serial.print("Analog 2 ");Serial.println(ads1.readADC_SingleEnded(2)); delay(10); 

Serial.println(""); 
delay(500); 
}

Transistor Output #

Wiring Transistor Outputs #

Programming Transistor Outputs #

Reading the relevant GPIO of the ESP32 gives the value of the Transistor Output. Refer to the GPIO allocation table in the datasheet for the Transistor Output GPIO.

#define OUTPUT1 23
void setup() { 
   Serial.begin(115200); 
   Serial.println("Device Starting"); 

   pinMode(OUTPUT1 , OUTPUT); 
} 
void loop() { 
   digitalWrite(OUTPUT1, HIGH); 
   delay(500); 
   digitalWrite(OUTPUT1, LOW); 
   delay(500); 

   Serial.println(""); 
   delay(500); 
}

Programming Buttons #

#define buttonPin 35
int  buttonState = 0;

void setup() {
 
  Serial.begin(9600);                             
  pinMode(buttonPin,INPUT);
}
void loop() { 
  Serial.print("Button: ");
  buttonState = analogRead(buttonPin);
