Adafruit AHTX0 (AHT10 & AHT20) Build Status

This is the Adafruit AHT10+AHT20 Humidity and Temperature Sensor library for Arduino

Tested and works great with the Adafruit AHT20 Breakout Board

This chip uses I2C to communicate, 2 pins are required to interface

adafruit_ahtx0's Issues

Resolution or Accuracy

There is a mixup of using sensor Resolution vs. Accuracy.

The AHT10 sensor example reports the following:

Adafruit AHT10/AHT20 test!
AHT10/AHT20 Found!
------------------------------------
Sensor:       AHTx0_T
Type:         Ambient Temp (C)
Driver Ver:   1
Unique ID:    4129
Min Value:    -40.00
Max Value:    85.00
Resolution:   0.30
------------------------------------

------------------------------------
Sensor:       AHTx0_H
Type:         Relative Humidity (%)
Driver Ver:   1
Unique ID:    4128
Min Value:    0.00
Max Value:    100.00
Resolution:   2.00
------------------------------------

The AHT10 temperature resolution is 0.01C but its typical accuracy is +/- 0.30 C.
The AHT10 RH resolution is 0.024% but its typical accuracy is +/- 2%.

What is expected of sensor to enter as "resolution" parameter?
I gather that is not made clear, and causes this mixup.

Code hangs when calling the .begin() initialization method

Environment

  • Arduino Board: Arduino Nano Every
  • Arduino IDE Version: 1.8.16
  • AHTX0 Library Version: 2.0.1
  • Sensor: DHT20

Context

I have a project that requires a temperature and humidity sensor, and after evaluating some of the alternatives I chose the DHT20 sensor (which uses the AHT20 under the hood) that Adafruit sells on their store. Due to space constraints the logical option was to go with the Nano Every microcontroller, one that I am aware uses a different processor than the Arduino UNO but I considered this to be a non-issue due to the software compatibility layer that Arduino includes which emulates the registers of an ATMEGA 328.

Summary of Issue

Loading up the example sketch (the one titled adafruit_aht_test) included with this library, it gets compiled and flashed to the Nano Every's memory without issue (see logs below). Upon opening the Serial Monitor (at 115200 baud to match the baud specified by the sketch), all I see is this message...

17:06:51.507 -> Adafruit AHT10/AHT20 demo!

...no readings from either sensor, no "AHT10 or AHT20 found" message and no "Could not find AHT? Check wiring" message either. This tells me that none of the code after the call to aht.begin() on line 9 is being reached, which leads me to believe that the core issue is not with the sketch code itself nor with my wiring (else I would be getting the "check wiring" message after initialization failed), but rather with this library. As a result, I am unable to resolve this issue myself as it is outside the scope of my knowledge and responsibility.

Steps to Reproduce

  1. Wire the SDA and SCL pins on the DHT20 to the matching pins in the Nano Every (D18 and D19 respectively).

  2. Connect the Arduino and DHT20 to 5V power

  • Note: the DHT20 is not connected to the Arduino's 5V pin. The Arduino and sensor are connected to the same power source.

  1. Install the latest version (2.0.1) of the AHTX0 library in the Arduino IDE Library Manager

  2. Install the Arduino megaAVR Boards package in the Board Manager

  3. Open the adafruit_aht_test example sketch

  4. Select the Arduino Nano Every as our board

  5. Enable registers emulation

  6. Upload the example sketch to the Nano Every

  7. Open the Serial Monitor at 115200 baud

Sketch Code

Adafruit_AHTX0/examples/adafruit_aht_test/adafruit_aht_test.ino

Lines 1 to 23 in 2d96149

#include <Adafruit_AHTX0.h>
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);
}

Things I Have Tried

  • Installing an older version of the library
  • Using a lower baud
  • Triple checked wiring
  • Tested a second DHT20 with my Arduino UNO R3 (same result)

Add alternative I2C address as parameter for the begin() method

The quality of the AHTX0 library is very good, but it is currently not possible to change the I2C address of the sensor to 0x39. By adding an additional parameter to the begin() method (with a default to guarantee compatibility) this can be solved with minimal effort.

AHTX0 wont work with ESP-01

  • Arduino board: ESP-01

  • Arduino IDE version (found in Arduino -> About Arduino menu): Arduino IDE 2.0.4

  • List the steps to reproduce the problem below (if possible attach a sketch or
    copy the sketch code in too):

    • Attach AHT10 to ESP-01 (SDA -> GPIO2, SCL -> GPIO0)
    • Add delay (1000) before first Serial.println. Becasue Serial port is shared with GPIO this time is to wait while serial port being setup.
    • Ad print commands for SDA and SCL definitions of wire.h
    • Compile https://github.com/adafruit/Adafruit_AHTX0/blob/master/examples/adafruit_aht_test/adafruit_aht_test.ino
    • The output is SDA=4, SCL=5. even if I add new define statements the ATHX0 library assumes these default pins.
    • The program cannot find the sensor and the program hangs.

use multii AHT10

Hello, how can I use several AHT10 sensors at the same time?

For example, 10 sensors on i2c
