Reliable fermentation monitoring

I use this to monitor temperature and humidity in my fermentation chamber. It has been running 24/7 for three months with zero drift. The waterproof casing gives me peace of mind against spills.

Good value for money

Works well with standard Arduino libraries. The only reason for 4 stars instead of 5 is that the connector wires are a bit stiff, making them hard to route in tight enclosures. Otherwise, great sensor.

Perfect for my greenhouse automation

This sensor works flawlessly with my Raspberry Pi setup. The waterproof probe handles the high humidity inside the greenhouse without any condensation issues. Reading accuracy seems spot on compared to my handheld meter.

Accurate and durable

Replaced an old analog sensor with this digital module. The difference in precision is night and day. The IIC interface saves GPIO pins on my microcontroller. Very satisfied with this purchase.

Great module, clear documentation needed

The hardware quality is excellent and the IIC communication is stable. However, the pinout diagram on the box was slightly faded. Once I found the datasheet online, integration took only minutes. Highly recommend for DIY projects.

Industrial grade performance

Purchased ten units for a warehouse monitoring project. All units reported consistent data upon arrival. The response time is quick, and the build quality feels very robust.

5 FAQ

Q: Does it come with a library for Python?

A: We do not provide proprietary software, but this sensor is compatible with popular open-source libraries like Adafruit_CircuitPython_SHT31 which works seamlessly with this module.

Q: Can the probe be submerged in water?

A: The probe is IP67 rated, meaning it can withstand temporary immersion up to 1 meter for 30 minutes. It is designed for high-humidity environments and protection against water jets, but continuous submersion is not recommended.

Q: How often does the sensor need calibration?

A: These sensors are factory calibrated and generally maintain accuracy for years under normal operating conditions. For critical industrial applications, we suggest verifying readings annually against a reference standard.

Q: Is this compatible with ESP32 boards?

A: Yes, this sensor uses the standard IIC protocol and operates at 3.3V-5.5V, making it fully compatible with ESP32, ESP8266, Arduino, and Raspberry Pi.

Q: What is the maximum cable extension length supported?

A: While the included cable is 1.5 meters, the IIC bus can typically be extended up to 3-5 meters using shielded cables, depending on your pull-up resistor configuration and bus speed.
