Reliable monitoring solution
I bought five of these to monitor different zones in my greenhouse. They have been running continuously for three weeks without any drift or connection drops. The pressure sensor adds a nice bonus for tracking storm fronts.

Compact and lightweight
Used this on a small custom drone for altitude hold. The BMP280 is very responsive to altitude changes. The form factor is compact enough not to add significant weight. Good product overall.

Perfect for Weather Stations
This module is exactly what I needed for my DIY weather station project. The I2C communication is stable, and the readings from both sensors match my calibrated equipment very closely. Easy to wire up with an Arduino.

High precision as advertised
Tested this against our lab-grade meter. The temperature and humidity readings were within the specified tolerance immediately. No calibration needed for general purpose use. Will buy more for future projects.

Easy to use with Raspberry Pi
As someone new to electronics, I was worried about compatibility. This worked straight out of the box with my Raspberry Pi 4 using Python libraries. The data precision seems very high compared to cheaper single-sensor modules.

Great value, minor documentation gap
The hardware quality is excellent for the price. Both sensors respond quickly. I deducted one star because the pinout diagram on the back was slightly faded, but a quick online search solved that. Highly recommended for hobbyists.
Q: Is this compatible with 5V logic levels like standard Arduino Uno?
A: Yes, the module includes a voltage regulator and level shifting, making it safe to use with both 3.3V and 5V microcontrollers.
Q: Which library do you recommend for ESP32?
A: For ESP32, we recommend using the Adafruit AHTX0 and Adafruit BMP280 libraries available in the Arduino Library Manager. They are well-maintained and easy to integrate.
Q: Can I use this outdoors directly in the rain?
A: The PCB itself is not waterproof. For outdoor use, you must place the module inside a breathable enclosure or weatherproof housing to protect the electronics from moisture and direct water exposure.
Q: Does this module come with header pins soldered?
A: No, the module is shipped without header pins soldered to allow for flexible mounting options. You will need to solder your own headers or wires.
Q: What is the update rate for the sensors?
A: The update rate depends on your code configuration, but the sensors are capable of providing new data approximately every 100ms to 500ms depending on the oversampling settings used.
