Great for smart home integration
Integrated this with an ESP32 to monitor bathroom humidity. The analog voltage scale is linear and easy to map in software.

Perfect for my Arduino project
The 0-3V output is exactly what I needed for my microcontroller ADC. Calibration was straightforward, and the readings match my reference meter closely.

Good value for humidity monitoring
Works well in my small greenhouse setup. The response time is decent, though it takes a moment to stabilize after a sudden change in humidity.

Easy to use for beginners
As someone new to sensors, I found the three-pin layout very intuitive. Documentation could be slightly better, but online examples helped.

Decent but needs calibration
Out of the box, the humidity reading was off by about 5%. After manual calibration in the code, it performs much better. Good for the price.

Reliable and compact
Small footprint makes it easy to integrate into tight spaces. I used two of these for a dual-zone dehumidifier control system without any issues.
Q: Does the 0-3V output correspond linearly to humidity percentage?
A: Yes, the voltage output is generally linear relative to humidity levels, but we recommend checking the datasheet graph for precise mapping at extreme temperatures.
Q: Is this module compatible with 5V Arduino boards?
A: Yes, the HRTM030 operates on a 3.3V to 5V supply, making it fully compatible with standard 5V Arduino boards like the Uno and Mega.
Q: Can this sensor be used outdoors?
A: While the sensor element is robust, the PCB itself is not waterproof. For outdoor use, please ensure it is housed in an IP-rated enclosure with proper ventilation.
Q: What is the thread size for mounting this sensor?
A: This specific module does not have threaded mounting; it is designed to be secured via the two screw holes on the PCB or soldered directly onto a custom board.
Q: What is the expected lifespan of the sensing element?
A: Under normal operating conditions within the specified temperature and humidity ranges, the sensing element typically lasts over 5 years.
