Good value for money
For the price, you get high accuracy. It's a bit sensitive to self-heating if you poll it too frequently, but following the datasheet recommendations solves this.

Essential for climate control
Using this to monitor my indoor greenhouse. The response time is fast enough to trigger my fans and misters effectively. Highly recommended for agricultural projects.

Reliable and consistent data
I bought a batch of ten for a distributed monitoring system. All units performed consistently out of the box. The breakout board makes wiring very simple.

Excellent documentation support
Found plenty of libraries for ESP32 and Raspberry Pi that work seamlessly with this module. The I2C address is standard and easy to configure.

Great sensor, minor soldering needed
The module works great, but the header pins were not included, so I had to solder them myself. Once connected, the humidity and temperature data is very precise.

Perfect for my weather station project
These sensors are incredibly accurate and easy to interface with an Arduino using the I2C library. The readings stabilize quickly and match my reference meter almost perfectly.
Q: Does this come with header pins soldered?
A: No, the module is shipped without header pins to allow flexibility for breadboard use or direct wire soldering. You will need to solder them separately.
Q: Can I use this outdoors in the rain?
A: The sensor chip itself is robust, but the breakout board is not waterproof. You must house it in a breathable, water-resistant enclosure for outdoor use.
Q: Is this module compatible with 5V logic levels?
A: Yes, the breakout board includes a voltage regulator and level shifting, making it safe to use with both 3.3V and 5V microcontrollers.
Q: What is the default I2C address for these sensors?
A: The default I2C address is typically 0x40, though some variants may use 0x44 or 0x45 depending on the specific chip configuration.
Q: How often should I calibrate this sensor?
A: These digital sensors are factory calibrated and generally do not require recalibration during their lifespan under normal operating conditions.
