Reliable for continuous monitoring

Running this 24/7 in our ventilation control system. It has been stable for three months now with no drift detected. Highly recommended for hazardous gas detection applications.

Robust build quality

Impressed by the construction. We tested it in a slightly dusty environment, and the TCD technology handled it better than expected without false alarms. Documentation was clear.

Excellent precision for lab use

We integrated this sensor into our environmental monitoring station. The thermal conductivity principle provides very stable readings for benzene levels, and the calibration data was accurate out of the box.

Good value, requires warm-up

The module works well for our industrial safety prototype. Just note that it needs about 2-3 minutes to warm up before giving consistent data. Once stabilized, the 100ppm range is perfect.

Easy integration with Arduino

Connected easily to our microcontroller via the analog output. The voltage curve is linear within the specified range. Would give 5 stars if the cable length was a bit longer.

Solid performance

Does exactly what it says on the tin. The response time is quick enough for our safety protocols. Support team was helpful when I had questions about the pinout configuration.

5 FAQ

Q: Is the output digital or analog?

A: This specific module offers both. It provides a linear analog voltage output proportional to concentration and also supports UART digital communication for direct data logging.

Q: What is the power consumption during operation?

A: The typical operating current is approximately 150mA at 5V. Please ensure your power supply can handle this load, especially during the initial heating phase.

Q: Does this sensor require regular calibration?

A: While the sensor is factory calibrated, we recommend an annual verification check depending on the usage environment to ensure maximum accuracy for toxic gas monitoring.

Q: How does humidity affect the reading?

A: Thermal Conductivity Detection can be influenced by extreme humidity changes. For best results in high-humidity environments, we suggest using the module with a standard moisture filter or compensation algorithm.

Q: Can this detect benzene concentrations above 100ppm?

A: The module is optimized for the 0-100ppm range. While it may register higher values, accuracy is not guaranteed beyond 100ppm, and exposure to extremely high concentrations may saturate the sensor temporarily.
