Voltage detection module Voltage Sensor Module for Arduino

Module description:
This module is based on the principle of the resistor divider designed to make the terminal interface input voltage reduced five times, Arduino analog input voltage up to 5V, then the input voltage of the voltage detection module cannot be greater than 5V × 5 = 25V (3.3V if used system, the input voltage cannot exceed 3.3Vx5 = 16.5V). Because Arduino AVR chips used in 10 AD, so the analog resolution of this module is 0.00489V (5V/1023), so the minimum input voltage detection module detects voltage is 0.00489V × 5 = 0.02445V.

Parameters:
Voltage input range: DC0-25V
Voltage detection range: DC0.02445V-25V
Voltage Analog Resolution: 0.00489V
Output interface: "+" connect DC5/3.3V, "-" connect GND, "s" connect Arduino AD pins.

Package Includes:
1 x Voltage detection module Voltage Sensor Module for Arduino


Reference Code:
#include
int val11;
int val2;
void setup()
{
pinMode(LED1,OUTPUT);
Serial.begin(9600);
Serial.println("Emartee.Com");
Serial.println("Voltage: ");
Serial.print("V");
}

void loop()
{
float temp;
val11=analogRead(1);
temp=val11/4.092;
val11=(int)temp;//
val2=((val11%100)/10);
Serial.println(val2);
delay(1000);

IIC I2C Logic Level Converter Bi-Directional Module 5V to 3.3V For Arduino

If you’ve ever tried to connect a 3.3V device to a 5V system, you know what a challenge it can be. bi-directional logic level converter is a small device that safely steps down 5V signals to 3.3V AND steps up 3.3V to 5V at the same time. This level converter also works with 2.8V and 1.8V devices. What really separates this Logic level converter from our previous versions is that you can successfully set your high and low voltages and step up and down between them safely on the same channel. Each level converter has the capability of converting 4 pins on the high side to 4 pins on the low side with two inputs and two outputs provided for each side.
The level converter is very easy to use. The board needs to be powered from the two voltages sources (high voltage and low voltage) that your system is using. High voltage (5V for example) to the ‘HV’ pin, low voltage (3.3V for example) to ‘LV’, and ground from the system to the ‘GND’ pin.
