Accurate compared to calibration unit
Tested this against a certified laboratory meter. The temperature variance was negligible and humidity was within the stated 2% tolerance. Excellent value for the price point.

Good sensor, mind the pull-up resistors
Works great with my ESP32 project. Just remember you need external pull-up resistors on the SDA and SCL lines if your board doesn't have them built-in. Otherwise, solid performance.

Perfect for environmental monitoring
I installed three of these in my greenhouse setup. The I²C communication is stable and the waterproofing holds up well against misting systems. Readings match my handheld hygrometer closely.

Survived heavy rain and snow
Mounted this outside under a small overhang. It has been through rain and freezing temperatures without any corrosion or data errors. The probe housing is very durable.

Great value, slightly slow response
For the price, you can't beat it. The response time is around 8 seconds as advertised, which is fine for logging but not for rapid change detection. Would buy again.
Q: Is the probe head fully submersible in water?
A: The probe has an IP67 rating, meaning it can withstand temporary immersion up to 1 meter for 30 minutes. It is designed for high humidity and rain, not continuous deep submersion.
Q: Can I extend the cable length to 5 meters?
A: Yes, you can extend the cable, but please ensure you use shielded wire for the I²C lines to prevent signal degradation over longer distances.
Q: What is the default I²C address?
A: The default I²C address is typically 0x44. Some variants may use 0x45 depending on the specific chip configuration, but 0x44 is the standard for this module.
Q: Do you provide a library for Arduino?
A: We recommend using the standard Adafruit SHT31 or Sensirion SHT3x libraries available in the Arduino Library Manager, as they are fully compatible with this sensor.
Q: Can I power this directly from a 5V Arduino pin?
A: Yes, the module supports an operating voltage range of 3.3V to 5.5V DC, so it is compatible with 5V logic boards like the Arduino Uno.
