Good but needs pull-up resistors
Sensor works great, but remember you need external pull-up resistors on the SDA and SCL lines if your board doesn't have them built-in. Once sorted, it's been rock solid.

High precision as advertised
The accuracy specs hold up well in real-world testing. Fast response time compared to older DHT sensors. Great value for professional prototyping.

Perfect for Arduino Projects
This sensor module works flawlessly with my Arduino Uno. The I2C communication is stable, and the library support makes integration very easy. Readings are consistent with my calibrated reference meter.

Compact and robust
Small form factor fits perfectly into my custom enclosure. The wide voltage range is a huge plus when working with different microcontrollers like ESP32 and STM32.

Excellent replacement part
Bought this to replace a faulty sensor in an existing project. Drop-in replacement worked immediately. Very happy with the purchase speed and product quality.

Reliable data logging
I am using three of these for a small greenhouse monitoring system. They have been running for two months without drift. Only giving 4 stars because the pin headers were not included, had to solder them myself.
Q: Do you provide sample code for ESP8266?
A: Yes, we provide example libraries and code snippets for ESP8266, ESP32, and Arduino on our GitHub repository linked in the product manual PDF.
Q: Is this compatible with Raspberry Pi GPIO?
A: Yes, it is fully compatible with Raspberry Pi. Ensure you enable the I2C interface in the Raspberry Pi configuration settings and connect VCC to 3.3V or 5V depending on your setup.
Q: Can this sensor be used outdoors in rain?
A: The sensor chip itself is sensitive to direct water exposure. While the module handles humidity well, it should be housed in a breathable enclosure to protect it from direct rain or condensation buildup.
Q: Does this module come with pre-soldered header pins?
A: No, the module typically comes without header pins to allow for flexible mounting options. You will need to solder your own headers or connect via wires.
Q: What is the default I2C address for this sensor?
A: The default I2C address is usually 0x40, but some variants may use 0x44 or 0x45. We recommend running an I2C scanner sketch to confirm the specific address of your unit.
