Perfect Upgrade
Swapped out my old SHT30s for these. Accuracy is noticeably better and the response time is faster. Highly recommend for any precision logging project.

Good Sensor, Small Pins
Works well but soldering the DFN package requires care if you are buying the bare sensor. The module version is much easier to handle.

Great for Arduino Projects
Easy to wire up using the Adafruit library. Readings are consistent and stable even in fluctuating conditions. Good value for the price.

Reliable Data
Using this in my greenhouse controller. Data is stable and hasn't drifted over the last three months of continuous operation.

Fast Delivery
Module arrived well protected. Tested immediately against a calibrated reference and it was within spec. Will buy again.
Q: Does this work with 5V logic microcontrollers?
A: Yes, but level shifting is recommended for the I²C lines to ensure long-term reliability when connecting to 5V boards.
Q: Is there an Arduino library available?
A: Yes, Sensirion provides official libraries, and it is also compatible with popular third-party SHT libraries.
Q: Can I use this sensor outdoors?
A: The sensor itself is robust but needs a proper enclosure to protect against direct rain and dust for outdoor use.
Q: What is the maximum sampling rate?
A: Configurable via software, typically up to 1Hz for low power modes, but can be higher depending on your power budget.
Q: Is it compatible with ESP32 boards?
A: Absolutely, works perfectly with ESP32 I²C pins. Just ensure you pull up the SDA and SCL lines correctly.
