Wio Terminal 读取 AHT10 传感器

Wio Terminal 读取 AHT10 传感器

本文介绍如何通过 Wio Terminal 读取 AHT10 传感器的温湿度数据。

AHT10 传感器

AHT10 是一款高精度、完全校准、贴片封装的温湿度传感器，采用 I2C 信号输出，可测量温度范围 -40~+85℃，分辨率达 0.01℃。

读取数据

这里使用 Adafruit AHTX0 库读取 AHT10 传感器数据，返回浮点类型的温度和湿度值。

#include Adafruit_AHTX0 aht;void setup() { Serial.begin(115200); Serial.println("Adafruit AHT10/AHT20 demo!"); if (! aht.begin()) { Serial.println("Could not find AHT? Check wiring"); while (1) delay(10); } Serial.println("AHT10 or AHT20 found");}void loop() { sensors_event_t humidity, temp; aht.getEvent(&humidity, &temp);// populate temp and humidity objects with fresh data Serial.print("Temperature: "); Serial.print(temp.temperature); Serial.println(" degrees C"); Serial.print("Humidity: "); Serial.print(humidity.relative_humidity); Serial.println("% rH"); delay(500);}
