Perfect for DIY Weather Stations

This SHT20 module works flawlessly with my Arduino project. The serial output is stable, and the readings match my professional hygrometer almost exactly. Great value for the price.

Reliable data logging

We used several of these for monitoring storage conditions. They connect easily to our PC setup. Only minor issue was the need to solder header pins, but that's expected.

Exceeded expectations

Very precise measurements even in fluctuating temperatures. The ability to connect directly to a PC for calibration checks is a huge plus.

Accurate and Fast

Impressed by how quickly this sensor stabilizes after power-on. The threshold control features are handy for triggering alarms when humidity gets too high.

Solid performance

Using it to control a dehumidifier relay. The threshold settings work well, though I wish the board came with a protective case included.

Great for university projects

Bought this for my final year thesis on environmental monitoring. The documentation provided by the seller helped me get it running on Python within an hour.

5 FAQ

Q: How long is the warranty for this sensor module?

A: This product comes with a standard 12-month manufacturer warranty covering defects in materials and workmanship under normal use.

Q: Can this sensor operate at 5V without a logic level converter?

A: Yes, the SHT20 module board includes a voltage regulator and is designed to operate safely within the 3.3V to 5.5V range without additional converters.

Q: What software do you recommend for viewing the sensor data on Windows?

A: You can use any standard serial terminal software like PuTTY, Tera Term, or the Arduino IDE Serial Monitor. Ensure the baud rate matches the sensor configuration (default is usually 9600).

Q: Is the threshold alarm feature hardware-based or does it require code?

A: The module supports configurable thresholds via command codes sent over the serial interface. Once set, the sensor can manage alerts, but initial setup requires sending specific commands from your microcontroller or PC.

Q: Does this module come with a USB cable to connect directly to a PC?

A: No, the module features a serial interface but does not include a USB cable. You will need a separate USB-to-TTL converter adapter to connect it to your PC.
