Hello

I have bought 2 AHT10 sensors and I want to do a small test to see if they work.

See code.

But getting a lot of errors?? I am using Arduino Uno R4 Wifi Thanks

#include <Wire.h>
#include <Adafruit_AHT10.h>

AHT10 myAHT(0x38);


void setup() {
  Wire.begin();
  Serial.begin(9600);
  Serial.println ("Initialising AHT10 Sensor");
  if (!myAHT10.begin ())
  Serial.println("Sensor error!");
  while(1);

}

void loop() {
 float temp = myAHT10.readTemperature ();
 float hum = myAHT10.readHumidity();
 Serial.print("Temp:"); 
 Serial.print (temp); 
 Serial("°C");
 Serial.print("Humidity:"); 
 Serial.print (hum); 
 Serial("%");
 delay (1000);

}

Errors

henrik_t7 Just follow the examples in the library, your first error on line 4 is because it does not look like the following. Just copy from working code.

Adafruit_AHT10 aht;
 

First computer 1959. Retired from my own computer company 2004.
Hardware - Expert in 1401, and 360, fairly knowledge in PC plus numerous MPU's and MCU's
Major Languages - Machine language, 360 Macro Assembler, Intel Assembler, PL/I and PL1, Pascal, Basic, C plus numerous job control and scripting languages.
My personal scorecard is now 1 PC hardware fix (circa 1982), 1 open source fix (at age 82), and 2 zero day bugs in a major OS.

@henrik_t7 Could you confirm that the fix I provided has answered your question? I plan on stepping away from the forum for perhaps a long time but want to wrap up loose ends.

I have tried one of the built-in Sketch but the arduino could not connect to the AHT10, maybe the AHT10 is defective and the wires might also be broken But sketch works fine without errors
