This circuit features a Wemos D1 Mini microcontroller interfaced with a pushbutton, a voltage sensor, an AHT21 temperature and humidity sensor, and an L298N motor driver controlling a linear actuator. The Wemos D1 Mini is powered by a 5V supply from an XL4015 DC-DC buck converter, which steps down the voltage from a 12V AGM battery charged by a solar panel through an MPPT charge controller. The microcontroller reads the voltage sensor data and controls the actuator based on programmed logic, while the pushbutton provides user input and the AHT21 sensor monitors environmental conditions.

The Xh-W3001 module typically has the following connections:
| Pin Name | Description |
|---|---|
| AC IN | Input for 110V AC power (for AC-powered models) |
| DC IN | Input for 12V DC power (for DC-powered models) |
| NO | Normally Open relay terminal for controlling external devices |
| COM | Common terminal for the relay |
| NC | Normally Closed relay terminal for controlling external devices |
| Sensor | Connection for the external temperature and humidity probe |
Note: Ensure you are using the correct power input (AC or DC) based on your module version.
The Xh-W3001 is straightforward to use in a variety of applications. Follow the steps below to integrate it into your project:

The Xh-W3001 can be used with an Arduino UNO for advanced control and monitoring. Below is an example of how to read the relay state and control it programmatically:
// Define the relay pin connected to the Xh-W3001 module
const int relayPin = 7;
void setup() {
// Initialize the serial communication for debugging
Serial.begin(9600);
// Set the relay pin as an input to monitor its state
pinMode(relayPin, INPUT);
}
void loop() {
// Read the state of the relay (HIGH = activated, LOW = deactivated)
int relayState = digitalRead(relayPin);
// Print the relay state to the Serial Monitor
if (relayState == HIGH) {
Serial.println("Relay is ON (Device is active)");
} else {
Serial.println("Relay is OFF (Device is inactive)");
}
// Add a small delay to avoid flooding the Serial Monitor
delay(500);
}
Note: The relay pin should be connected to the Arduino's digital input pin. Ensure proper voltage level matching between the Arduino and the Xh-W3001.

Q1: Can I use the Xh-W3001 with a 24V DC power supply?
A1: No, the Xh-W3001 is designed for either 12V DC or 110V AC power, depending on the model. Using a 24V DC supply may damage the module.
Q2: Is the external probe replaceable?
A2: Yes, the external probe can be replaced if it becomes damaged. Ensure the replacement probe is compatible with the Xh-W3001.
Q3: Can the module control both heating and cooling devices simultaneously?
A3: No, the module can control only one device at a time through its relay. You can configure it for either heating or cooling, but not both simultaneously.
Q4: How do I reset the module to factory settings?
A4: Refer to the module's user manual for specific instructions on resetting to factory defaults. Typically, this involves holding down a button for a few seconds.
By following this documentation, you can effectively use the Xh-W3001 module for your temperature and humidity monitoring needs.
