Perfect for my weather station project

The I2C interface makes integration with my Raspberry Pi incredibly easy. The readings are stable and match my reference thermometer almost perfectly. Highly recommended for DIY enthusiasts.

Bulk order success

Bought 20 units for our makerspace workshop. Every single one worked out of the box. Consistent quality across the batch which is rare for components at this price point.

Reliable monitoring for my greenhouse

I have three of these running in my automated greenhouse setup. They have been running 24/7 for two months without any drift or connection issues. The capacitive sensor seems much more durable than resistive ones.

Good accuracy, clear documentation

Works exactly as described. The datasheet provided by the seller was very helpful for writing the driver code. Only giving 4 stars because the header pins were slightly bent upon arrival, but easy to fix.

Great starter sensor

As someone new to embedded systems, this module was very forgiving. The voltage range is wide enough that I didn't worry about frying it immediately. Great value for the price.

Solid performance

Using this in a professional data logging application. The response time is adequate for environmental monitoring. Would prefer if it came with a waterproof housing option, but the module itself is excellent.

5 FAQ

Q: What is the maximum cable length for reliable communication?

A: For standard I2C communication, we recommend keeping the cable length under 30cm (approx. 1 foot) to ensure signal integrity. For longer distances, you may need an I2C extender or buffer.

Q: Is this compatible with Arduino Uno?

A: Yes, the AM2320 module operates on 3.3V to 5.5V, making it fully compatible with the Arduino Uno. You will need to connect the SDA and SCL pins to the appropriate I2C pins on your board.

Q: Is there a library available for Python?

A: Yes, there are several open-source libraries available for Python, particularly for Raspberry Pi users. Popular options include `adafruit-circuitpython-am2320` and generic I2C humidity sensor libraries.

Q: Can this measure dew point?

A: The sensor measures temperature and relative humidity directly. However, you can easily calculate the dew point in your code using standard formulas based on the data provided by the sensor.

Q: Does this require external pull-up resistors?

A: Most breakout modules, including this one from Xinwei, come with onboard pull-up resistors. You can connect it directly to your microcontroller without adding external components.
