Solid component for IoT
Integrated this into an ESP32 home automation system. It has been running for three months without drift or connection issues. Highly recommended for indoor climate control.

Works great once wired correctly
Make sure you use the correct pinout; I initially swapped data and VCC. Once corrected, it provided consistent data. The included header pins were a nice touch.

Reliable and easy to code
Used the standard DHT library and it detected the sensor immediately. No calibration needed out of the box. The soldering points on the module are large enough for beginners.

Better than the DHT11
Upgraded from the blue DHT11 sensor and the difference in precision is noticeable, especially in lower humidity environments. Well worth the small extra cost for serious projects.

Perfect for my weather station project
This sensor works flawlessly with my Arduino Uno. The readings are stable and match my calibrated thermometer closely. The module form factor makes wiring very easy compared to the bare sensor.

Good accuracy, slow sampling
Great for monitoring my greenhouse humidity. Just remember it only updates every 2 seconds, so don't expect real-time rapid changes. For general environmental monitoring, it is excellent.
Q: What is the maximum cable length recommended for the data pin?
A: For reliable communication, we recommend keeping the cable length under 20 meters. Longer distances may require a stronger pull-up resistor or signal buffering.
Q: Do you provide sample code for Raspberry Pi?
A: Yes, please visit our GitHub repository linked in the product manual PDF, which contains Python scripts specifically tested for Raspberry Pi GPIO.
Q: Can I use this sensor outdoors in the rain?
A: No, this sensor is not waterproof. It should be housed in a ventilated but weatherproof enclosure if used outside to protect the electronics from moisture.
Q: Does this module come with a pull-up resistor installed?
A: Yes, the TELESKY module includes a built-in 10k pull-up resistor on the data line, so you do not need to add one externally.
Q: Is this compatible with 5V logic levels?
A: Yes, the module operates between 3.3V and 6V, making it fully compatible with both 3.3V and 5V microcontrollers like Arduino and Raspberry Pi.
