Best in class for the price

Compared to other sensors in this price range, the SHT35 variant on this module offers superior accuracy. The digital output eliminates noise issues I had with analog sensors.

Good accuracy, small footprint

Works well in my greenhouse monitoring system. The only reason for 4 stars is that the pin headers were not included, so I had to solder them myself. Otherwise, excellent sensor.

Solid performance

Using this to control my bathroom fan based on humidity levels. It responds quickly to steam. Would give 5 stars if the board had mounting holes.

Perfect for my weather station project

The I2C communication was easy to set up with my Arduino. The readings are consistent and match my calibrated reference meter very closely. Great value for the price.

Reliable and stable

I have been running three of these modules for two months straight without any drift. The wide voltage range makes it very flexible for different microcontroller setups.

5 FAQ

Q: Is this module compatible with Raspberry Pi?

A: Yes, this module uses standard I2C communication and operates at 3.3V or 5V, making it fully compatible with Raspberry Pi GPIO pins.

Q: What is the default I2C address?

A: The default I2C address is typically 0x44, but some variants allow changing the address via specific commands if you need multiple sensors on the same bus.

Q: Does it come with example code?

A: We do not include physical code sheets, but there are extensive open-source libraries available for Arduino, ESP32, and Python that support this sensor series.

Q: How often should I calibrate this sensor?

A: These digital sensors are factory-calibrated and generally do not require recalibration during their lifespan under normal operating conditions.

Q: Can this sensor be used outdoors?

A: While the sensor itself is robust, the breakout board is not waterproof. For outdoor use, please house it in an IP65-rated enclosure with a breathable membrane.
