Perfect for Home Automation Projects
I bought this kit to monitor my greenhouse conditions. The DHT22 sensors are incredibly accurate compared to my old analog ones. Setup with my ESP32 was seamless using standard libraries.

Works well but slow sampling
The sensors work as advertised, but remember the DHT series has a 2-second sampling limit. If you need faster updates, stick to the SHT30 models included in the pack.

Excellent compatibility
Tested all four types with both Arduino Uno and Raspberry Pi Zero. All recognized immediately. Having the AM2302 and SHT variants gives great flexibility for different precision needs.

Reliable data collection
Been running these for three months straight logging server room temps. No drift detected and they haven't failed once. The build quality on the PCBs is solid.

Easy for beginners
As someone new to IoT, I found these modules very forgiving. The digital output makes wiring simple, and there are plenty of tutorials online for all the models included in this set.

Great value bundle
Good variety of sensors in one pack. The SHT30 seems slightly more responsive than the DHT11. Only giving 4 stars because the jumper wires included were a bit short for my specific enclosure.
Q: Is there a library available for Python on Raspberry Pi?
A: Yes, popular libraries like 'Adafruit_CircuitPython_DHT' and 'RPi.GPIO' support these sensors. You can easily find installation guides and code examples in our documentation section.
Q: What is the difference between the DHT11 and DHT22 included here?
A: The DHT22 (AM2302) offers higher accuracy and a wider temperature/humidity range compared to the DHT11. The DHT11 is suitable for basic indoor monitoring, while DHT22 is better for precise applications.
Q: What is the maximum cable length for reliable readings?
A: For best results, keep the cable length under 20 meters. Longer distances may introduce signal noise or voltage drop, requiring shielded cables or additional signal conditioning.
Q: Do I need external pull-up resistors?
A: Most modules in this kit come with an onboard pull-up resistor. However, if you are building a custom circuit without the module PCB, a 4.7kΩ to 10kΩ pull-up resistor on the data line is required.
Q: Can these sensors be used outdoors directly?
A: While the sensor elements are robust, the PCB modules are not waterproof. We recommend placing them inside a breathable weatherproof enclosure for outdoor use to protect the electronics from rain.
