Accurate readings
Compared with a professional hygrometer and the SHT31 was surprisingly accurate. Great for calibration tasks in IoT deployments.

Works with ESP32
Had to enable internal pull-up resistor in the code for stable readings. Once configured, it has been running for months without issues.

Great for learning
Used this for my university embedded systems project. Documentation online is plentiful which helped me debug my code quickly.

Perfect for Weather Station
Used the SHT30 for my home weather station project. The readings are consistent and match my indoor thermometer closely. Easy to wire up to the ESP32.

Good value pack
Got a mix of sensors in this lot. DHT11 is basic but works fine for simple projects. Would have liked more SHT30 modules but overall good value.
Q: Is this sensor waterproof?
A: No, the sensor electronics are not waterproof. Please house them in a ventilated enclosure if used outdoors.
Q: What is the maximum cable length recommended?
A: We recommend keeping the cable under 20 meters to ensure signal integrity on the single-bus interface.
Q: Which library works best for these sensors?
A: The Adafruit DHT library is highly recommended for Arduino and ESP platforms. For SHT30, the Adafruit SHT31 library works well.
Q: Are these modules 5V tolerant?
A: Yes, most modules include a voltage regulator and pull-up resistor, making them safe for 5V logic systems.
Q: What is the main difference between DHT11 and DHT22?
A: DHT22 offers better accuracy and a wider temperature range compared to the DHT11, which is more basic and budget-friendly.
