Fast response time

Impressed by how quickly the SHT30 reacts to changes in environment. Great for triggering fans or humidifiers in real-time automation scripts.

Documentation could be better

The sensor itself works fine, but the pinout diagram on the packaging was slightly confusing for the SHT31 model. Had to look up the datasheet online to confirm wiring.

Reliable for greenhouse monitoring

Running three of these in my automated greenhouse setup. They have been stable for months now, handling the humidity changes without drifting.

Perfect for my weather station

I used the SHT30 version for a home weather station project. The readings are consistent and match my professional hygrometer closely. Easy to wire up to an ESP32.

Solid build quality

The probe feels durable and the cable length is sufficient for most enclosures. Only wish it came with a small mounting bracket included.

Good value for learning

Bought the DHT11 bundle for a school project. It works well enough for demonstration purposes, though I noticed the DHT22 is much more accurate if you need precision.

5 FAQ

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

A: Yes, these modules operate within a 3.3V to 5V range, making them fully compatible with standard 5V Arduino boards like the Uno and Mega.

Q: How long is the cable connecting the probe to the board?

A: The standard cable length for the digital switch probe is approximately 1 meter (3.3 feet), which is suitable for most DIY enclosures.

Q: Do you provide sample code for Raspberry Pi?

A: Yes, we host Python libraries and example scripts for Raspberry Pi on our official GitHub repository, linked in the product manual PDF.

Q: What is the main difference between the DHT11 and DHT22 included in this listing?

A: The DHT22 (AM2302) offers higher accuracy and a wider temperature/humidity range compared to the DHT11, which is better suited for basic applications.

Q: Can I use this sensor outdoors directly in the rain?

A: While the probe is robust, the electronic module itself is not waterproof. We recommend placing the module inside a waterproof enclosure while exposing only the probe tip if necessary.
