🌡️ Simple_AHT10

Simple_AHT10 is a lightweight, macro-driven, non-blocking library for AHT10 and AHT20 temperature/humidity sensors.
Built on top of the Simple_Wire I²C communication library, it's designed for performance, portability, and ease of use across a range of platforms.

🚀 Features

• ✅ Non-blocking measurements using loop()
• ✅ Callback-based API for real-time sensor updates
• ✅ Supports AHT10 & AHT20 sensors
• ✅ I²C auto-scan and address configuration
• ✅ Fully compatible with ESP32-WROOM-32U, Arduino UNO, STM32, and more
• ✅ No std::function or dynamic memory — safe for memory-limited MCUs

🧰 Usage Example (ESP32)

#include <Simple_AHT10.h>

#define SDA_PIN 14
#define SCL_PIN 15

Simple_AHT10 aht;  // Default address = 0x38

// Callback function to handle measurement results
void SensorCallback(float temp, float hum) {
  Serial.printf("Temp: %.2f °C, Hum: %.2f %%\n", temp, hum);
}

void setup() {
  Serial.begin(115200);
  while (!Serial);  // Wait for Serial monitor (USB)

  // Initialize I2C communication
  aht.begin(SDA_PIN, SCL_PIN);
  // Set the callback function to receive data
  aht.SetCallbackFunction(SensorCallback);

  // Start automatic measurements every 2000 ms
  aht.TriggerMeasurement(2000);
}

void loop() {
  aht.loop();  // Handle non-blocking logic
}
