Easy integration with ESP32
Connected directly to an ESP32 using standard libraries. The documentation provided by the seller was clear, and the pinout is standard. No calibration needed out of the box.

Reliable in high humidity
Using these in a tropical greenhouse setup. They handle 95%+ humidity without condensation issues or drift. The response time is incredibly fast compared to older DHT sensors.

Best SHT40 module available
I've tried several vendors, and this module has the cleanest PCB layout and best soldering quality. The voltage regulator on board makes it versatile for 3.3V and 5V logic systems.

Solid performance for the price
We bought ten units for a student project. Nine worked perfectly immediately; one had a slight offset which we calibrated in software. Overall, excellent value for an industrial-grade component.

Perfect for industrial data logging
Integrated this module into our warehouse monitoring system. The I2C communication is stable and the readings are consistent even in fluctuating environments. Highly recommended for professional use.

Great accuracy, needs pull-up resistors
The sensor itself is fantastic and very precise. Just remember that you need to add external pull-up resistors for the I2C lines if your board doesn't have them built-in. Once set up, it works flawlessly.
Q: What is the maximum cable length recommended for the I2C connection?
A: For reliable I2C communication, we recommend keeping cable lengths under 30cm. For longer distances, please use an I2C extender or buffer chip.
Q: Does this sensor require periodic recalibration?
A: The SHT40 is factory calibrated and typically does not require user recalibration during its operational lifetime under normal conditions.
Q: Can I power this with 5V directly from an Arduino?
A: Yes, the module supports an input voltage range of 1.7V to 5.5V, so connecting it directly to the 5V pin on an Arduino is safe and supported.
Q: Does this module come with a cable or is it just the bare board?
A: This listing is for the bare module only. Cables are not included, but the pin spacing is standard 2.54mm, so any generic jumper wires will fit.
Q: Is there a library available for Raspberry Pi?
A: Yes, the SHT40 is compatible with standard Python libraries like 'shtsensor' or generic Adafruit CircuitPython libraries available via pip.
