Design with JST XH Socket 4pin in Cirkit DesignerThe JST XH Socket 4-Pin (B4B-XH-AM) is a compact and reliable connector designed for connecting wires to printed circuit boards (PCBs). Manufactured by JST, this connector is known for its secure connection and ease of use. It is widely used in various electronic applications, including consumer electronics, industrial equipment, and hobbyist projects.
This circuit consists of a 40-pin connector interfacing with four pushbuttons and a UBS power supply. The pushbuttons are used as inputs to the connector, which then relays the signals to other components or systems. The UBS power supply provides the necessary 24V power to the pushbuttons and the common ground for the circuit.

This circuit features an ESP32 microcontroller interfaced with a PZEM004T power monitoring module and a 4-channel relay module controlling multiple AC LED bulbs. The ESP32 uses GPIO pins to control the relays, which in turn switch the LED bulbs on and off. The PZEM004T is connected to the ESP32 for communication and to a current sensor for monitoring power consumption of the connected load through the relay contacts.

// Example code to read data from a sensor connected via JST XH Socket 4-Pin
// Connect VCC to 5V, GND to GND, and Signal/Data to A0 on the Arduino UNO
const int sensorPin = A0; // Pin connected to the sensor's data line
int sensorValue = 0; // Variable to store the sensor value
void setup() {
Serial.begin(9600); // Initialize serial communication at 9600 baud
pinMode(sensorPin, INPUT); // Set the sensor pin as an input
}
void loop() {
sensorValue = analogRead(sensorPin); // Read the value from the sensor
Serial.print("Sensor Value: "); // Print the sensor value to the serial monitor
Serial.println(sensorValue);
delay(1000); // Wait for 1 second before reading again
