Great accuracy, slow shipping
The sensor readings match our calibrated lab equipment very closely. The waterproofing holds up well in high humidity. Only downside was the delivery took longer than expected.

Good sensor, confusing pinout diagram
The sensor itself works fine once connected, but the pinout diagram in the manual was slightly unclear for the SHTC3 variant. Had to test pins manually.

Easy to integrate with Arduino
Plug and play with standard libraries. The code examples provided in the documentation worked immediately. Great value for a waterproof digital sensor.

Perfect for industrial monitoring
The stainless steel probe is robust and the I2C communication is stable. Integrated it into our greenhouse system without any issues. Highly recommended for harsh environments.

Reliable for long-term data logging
We have deployed ten of these units for six months now. Zero drift detected and the stainless steel housing shows no signs of corrosion. Excellent build quality.

Best waterproof probe in this price range
Superior performance compared to plastic housed sensors we used previously. The response time is quick and the data is consistent across multiple units.
Q: Is this compatible with Raspberry Pi GPIO?
A: Yes, as long as your Raspberry Pi has I2C enabled, this sensor will work perfectly with 3.3V logic levels.
Q: Can the cable be extended beyond 1 meter?
A: Yes, you can extend the cable, but for I2C stability over long distances, we recommend using shielded twisted pair cables and keeping the total length under 5 meters.
Q: What is the difference between SHT40 and SHT30 models?
A: The SHT40 offers slightly higher accuracy and faster response times compared to the SHT30, though both share the same form factor and interface.
Q: Is the stainless steel probe food grade safe?
A: The probe is made of 304 Stainless Steel which is generally food-safe, but this specific module is designed for environmental monitoring, not direct food immersion certification.
Q: Does it come with calibration certificates?
A: Standard units are factory calibrated. If you require an individual ISO calibration certificate, please contact us before placing your order for a custom quote.
