The board connects to various sensors, including infrared, ultrasonic, or capacitive sensors, to detect the presence of a user's hand or object.
The board connects to various sensors, including infrared, ultrasonic, or capacitive sensors, to detect the presence of a user's hand or object.
Upon detection, the board sends a signal to the dispenser motor to activate and dispense a predetermined amount of sanitizer.
The board features a built-in timer that allows for adjustable dispenser intervals, ensuring a consistent and controlled flow of sanitizer.
The board is equipped with LED indicators that provide visual feedback on the dispenser's status, including power, sensor detection, and dispenser operation.
The board can integrate with various communication protocols, such as Wi-Fi, Bluetooth, or RS-485, to enable remote monitoring and control of the dispenser system.

Automatic Sanitizer Dispenser Control Board DocumentationOverviewThe Automatic Sanitizer Dispenser Control Board is a microcontroller-based board designed to control and automate the dispensing of sanitizers in various applications, such as public restrooms, healthcare facilities, and commercial buildings. This board is equipped with sensors, relays, and communication interfaces to facilitate seamless integration with other IoT devices.Technical SpecificationsMicrocontroller: ESP32
Operating Voltage: 5V
Communication Interfaces: Wi-Fi, UART, I2C
Sensors: Infrared proximity sensor, Reed switch
Relays: 2x SPDT relays (for pump and valve control)
Power Consumption: 50mA (average), 100mA (peak)Programming the Control BoardThe Automatic Sanitizer Dispenser Control Board can be programmed using the Arduino IDE or ESP32's native SDK. The following code examples demonstrate how to use this component in various contexts:Example 1: Basic Automatic DispensingIn this example, we will demonstrate how to use the control board to automatically dispense sanitizer when someone approaches the dispenser.```c
#include <WiFi.h>
#include <Arduino.h>#define PROXIMITY_SENSOR_PIN 32
#define RELAY_PIN 15
#define DISPENSE_TIME 500 // millisecondsvoid setup() {
// Initialize the proximity sensor pin as an input
pinMode(PROXIMITY_SENSOR_PIN, INPUT);
// Initialize the relay pin as an output
pinMode(RELAY_PIN, OUTPUT);
// Initialize Wi-Fi (optional)
WiFi.begin(ssid, password);
while (WiFi.status() != WL_CONNECTED) {
delay(1000);
Serial.println("Connecting to Wi-Fi...");
}
Serial.println("Connected to Wi-Fi");
}void loop() {
// Read the proximity sensor value
int sensorValue = digitalRead(PROXIMITY_SENSOR_PIN);
// If someone is near, dispense sanitizer
if (sensorValue == HIGH) {
digitalWrite(RELAY_PIN, HIGH);
delay(DISPENSE_TIME);
digitalWrite(RELAY_PIN, LOW);
}
// Optional: Send a notification to a central server or IoT hub
// WiFiClient client;
// client.setServer("http://example.com/sanitizer_api", 80);
// client.println("Dispensed sanitizer!");
// client.stop();
}
```Example 2: IoT-Enabled Sanitizer Dispenser with Real-Time MonitoringIn this example, we will demonstrate how to use the control board to connect to a cloud-based IoT platform and monitor the sanitizer dispenser's status in real-time.```c
#include <WiFi.h>
#include <Arduino.h>
#include <HTTPClient.h>#define RELAY_PIN 15
#define DISPENSE_TIME 500 // millisecondsconst char ssid = "your_wifi_ssid";
const char password = "your_wifi_password";
const char iotHubUrl = "https://your_iot_hub.com/api/sanitizer";WiFiClient client;
HTTPClient http;void setup() {
// Initialize the relay pin as an output
pinMode(RELAY_PIN, OUTPUT);
// Initialize Wi-Fi
WiFi.begin(ssid, password);
while (WiFi.status() != WL_CONNECTED) {
delay(1000);
Serial.println("Connecting to Wi-Fi...");
}
Serial.println("Connected to Wi-Fi");
}void loop() {
// Dispense sanitizer every 10 seconds
digitalWrite(RELAY_PIN, HIGH);
delay(DISPENSE_TIME);
digitalWrite(RELAY_PIN, LOW);
// Send a POST request to the IoT hub with the dispenser's status
http.begin(client, iotHubUrl);
http.addHeader("Content-Type", "application/json");
int httpResponseCode = http.POST("{""status"":""dispensed""}");
// Check the response code
if (httpResponseCode > 0) {
Serial.println("Sent data to IoT hub successfully");
} else {
Serial.println("Error sending data to IoT hub");
}
http.end();
// Wait for 10 seconds before the next dispense cycle
delay(10000);
}
```Example 3: Integration with a Cloud-Based DashboardIn this example, we will demonstrate how to use the control board to integrate with a cloud-based dashboard, enabling remote monitoring and control of the sanitizer dispenser.```c
#include <WiFi.h>
#include <Arduino.h>
#include <WiFiClient.h>
#include <ArduinoJson.h>#define RELAY_PIN 15
#define DISPENSE_TIME 500 // millisecondsconst char ssid = "your_wifi_ssid";
const char password = "your_wifi_password";
const char dashboardUrl = "https://your_cloud_dashboard.com/api/sanitizer";WiFiClient client;
DynamicJsonDocument jsonDoc(2048);void setup() {
// Initialize the relay pin as an output
pinMode(RELAY_PIN, OUTPUT);
// Initialize Wi-Fi
WiFi.begin(ssid, password);
while (WiFi.status() != WL_CONNECTED) {
delay(1000);
Serial.println("Connecting to Wi-Fi...");
}
Serial.println("Connected to Wi-Fi");
}void loop() {
// Read the dispenser's status
bool isDispenserEmpty = false; // Replace with actual sensor reading
// Create a JSON object to send to the dashboard
jsonDoc["dispenser_status"] = isDispenserEmpty ? "empty" : "full";
jsonDoc["last_dispense_time"] = millis();
// Convert the JSON object to a string
String jsonString;
jsonDoc.printTo(jsonString);
// Send a POST request to the dashboard with the dispenser's status
client.setServer(dashboardUrl, 80);
client.println("POST /api/sanitizer HTTP/1.1");
client.println("Host: your_cloud_dashboard.com");
client.println("Content-Type: application/json");
client.println("Content-Length: " + String(jsonString.length()));
client.println();
client.print(jsonString);
// Check the response code
int httpResponseCode = client.responseStatusCode();
if (httpResponseCode == 200) {
Serial.println("Sent data to dashboard successfully");
} else {
Serial.println("Error sending data to dashboard");
}
// Wait for 10 seconds before the next update cycle
delay(10000);
}
