Compact module that combines AHT20 and BMP280 digital sensors to provide precise temperature, humidity and atmospheric pressure measurements, compatible with Arduino and other development boards, and able to operate with voltages between 2.8V and 5VDC.
It is ideal for IoT applications, weather stations, home automation or educational projects, as it operates on the I2C interface and supports the simultaneous connection of multiple devices.
It has low power consumption and offers stable and fast data transmission. Connection is easily made on the dedicated SCL and SDA pins.
To work, both the Adafruit AHT20 and BMP20 libraries will need to be used.
Specifications:
Supply voltage: DC 2.8 – 5.0VDC
Logic voltage: 3.3 – 5VDC
Integrated sensors: AHT20 (temperature and humidity), BMP280 (atmospheric pressure)
Communication interface: I2C
AHT address: 0x38
BMP address: 0x76 (or 0x77)
Dimensions: 15 x 15 mm
Pinout:
Connect the module to the development board as follows:
AHT20 + BMP280 Module Pin | Function | Arduino UNO R3 pin |
VCC | feeding | 5V (or 3.3V) |
GND | Mass | GND |
SCL | I2C Clock | A5 |
SDA | I2C data | A4 |
Use:
Make sure the supply voltage is within the range of 2.0V - 5.0V.
Open Arduino IDE and in Tools->Manage Libraries search for and install BMP280 by Adafruit.
Do the same for the AHT10 library.
Sensors can be read individually (AHT or BMP) or can be read together.

După programarea atentă și construirea îngrijită a montajului Arduino cu acest senzor, am obținut citiri precise ale temperaturii, umidității și presiunii atmosferice. Astfel se poate construi o mică stație meteo.
