Perfect for IoT Projects

This sensor is incredibly easy to integrate with Arduino and ESP32 boards. The I2C communication is stable, and the readings are consistent with my calibrated reference meter. Great value for the price.

Bulk buy success

Purchased ten units for our makerspace workshop. Every single one worked out of the box. The library support for Python and C++ makes it accessible for beginners and experts alike.

Small and Mighty

The form factor is tiny, which made it easy to fit inside a custom 3D printed enclosure. Response time to changes in humidity is surprisingly fast. No complaints at all.

Good accuracy for the cost

I am using four of these in different rooms. They all report very similar values when placed next to each other, indicating good manufacturing consistency. One star off because the header pins were slightly crooked on one unit.

Reliable but needs calibration

Works well for monitoring my indoor garden. The temperature reading was spot on, but I had to adjust the humidity offset slightly in the code. Once calibrated, it has been running for weeks without issues.

5 FAQ

Q: Does the package include sample code?

A: The physical package does not include a CD or paper manual with code, but we provide a link in the product description to a GitHub repository with extensive example libraries for Arduino, ESP8266, and Raspberry Pi.

Q: What is the default I2C address for this sensor?

A: The default I2C address is typically 0x40. However, some variations allow you to change the address by soldering a jumper if you need to connect multiple sensors on the same bus.

Q: Is this module compatible with 5V Arduino Uno boards?

A: Yes, the module includes a voltage regulator and level shifting, making it safe to use with 5V logic boards like the Arduino Uno, although the sensor itself operates at lower voltages.

Q: How long does the battery last in low power mode?

A: Battery life depends heavily on your specific usage pattern and battery capacity. In deep sleep mode with hourly measurements, users have reported lasting several months on a standard coin cell battery.

Q: Can this sensor be used outdoors in the rain?

A: The sensor chip itself is not waterproof. While it can measure outdoor air conditions, it must be housed in a weatherproof enclosure with a breathable membrane to protect it from direct water exposure.
