Good quality, small footprint
The module is compact and fits well on my custom PCB. The only minor issue is that the pin headers were slightly loose, but a little solder fixed that immediately.

Reliable for agricultural monitoring
I bought five of these for my greenhouse automation system. They have been running 24/7 for a month without any drift or connection issues. Highly recommended for DIY agriculture projects.

Best in class for the price
Compared to other sensors in this price range, the RHI-112A offers superior accuracy. The special offer made it an absolute steal. Will definitely order more for future batches.

Solid performance, quick shipping
Good sensor overall. The humidity response is slightly slower than expected in rapid changes, but for general monitoring, it works flawlessly. The I2C address was clearly documented.

Perfect for my weather station project
The RHI-112A module was incredibly easy to integrate with my Arduino setup. The readings are stable and match my reference thermometer almost exactly. Great value for the precision offered.

Great documentation support
The library examples provided made coding this a breeze. Data consistency is excellent even in high-humidity environments. No condensation issues so far.
Q: Can I daisy-chain multiple sensors on the same bus?
A: The RHI-112A has a fixed I2C address. To use multiple units, you will need an I2C multiplexer chip to switch between them on the same bus.
Q: What is the maximum cable length for reliable I2C communication?
A: For standard I2C speeds, we recommend keeping cable lengths under 30cm without pull-up resistor adjustments. For longer distances, consider using an I2C extender or buffer.
Q: Is this module compatible with Raspberry Pi GPIO?
A: Yes, the RHI-112A operates on 3.3V logic and supports I2C, making it fully compatible with Raspberry Pi models. Just ensure you enable the I2C interface in your OS settings.
Q: Is there a calibration certificate included?
A: Each unit is factory calibrated, but individual calibration certificates are not included with the standard special offer package. Bulk orders over 100 units may request calibration reports.
Q: Does this come with a waterproof casing?
A: No, the module itself is not waterproof and is designed for indoor use or protected enclosures. For outdoor use, we recommend placing it inside an IP65-rated project box with ventilation.
