Reliable and accurate

I've deployed six of these in my greenhouse monitoring system. They have been running stable for three weeks now with consistent readings across all units.

Great value for the price

Works exactly as described. Setup took less than 10 minutes. The only reason for 4 stars instead of 5 is that the documentation could be slightly more detailed for beginners.

Exactly what I needed

Using this for a smart fan controller. The accuracy helps prevent the fan from turning on and off too frequently due to minor fluctuations.

Perfect upgrade from DHT11

The precision on this GXHT11 is noticeably better than the standard DHT11 I was using before. The single-bus communication makes wiring incredibly simple for my Arduino projects.

Solid performance

Good build quality on the PCB. The response time is quick enough for real-time logging. It handles humidity spikes well without lagging.

Easy to integrate

As someone new to sensors, I was worried about the protocol. However, existing DHT libraries worked perfectly with minor adjustments. Highly recommended for learning.

5 FAQ

Q: Is this module compatible with Raspberry Pi GPIO pins?

A: Yes, the GXHT11 operates at 3.3V-5V and is fully compatible with Raspberry Pi GPIO pins using a standard pull-up resistor configuration.

Q: Does it come with a protective filter cover?

A: This specific module version does not include a separate sintered metal filter cover, but the sensor element is robust for indoor general-purpose use.

Q: What is the maximum cable length recommended for the data line?

A: For reliable single-bus communication, we recommend keeping the cable length under 2 meters without signal amplification or shielding.

Q: Is calibration required before first use?

A: No, the GXHT11 comes factory-calibrated. You can start reading data immediately after connecting power and data lines.

Q: Can I use the standard DHT11 Arduino library?

A: In most cases, yes. Since it mimics the DHT11 timing protocol, many standard libraries work, though some users prefer libraries specifically optimized for higher precision sensors.
