Reliable for integration

Bought multiple units for a batch of air purifiers. Consistency across all modules is impressive. No dead on arrival.

Good accuracy, power sensitive

Works well for our prototype units. Just ensure you have a stable 5V supply or readings might fluctuate. Otherwise solid hardware.

Excellent for DIY Air Quality Monitors

Integrated this into my ESP32 project seamlessly. The data output is consistent and matches my reference meter closely. Highly recommend for hobbyists.

Documentation could be clearer

The sensor works but the pinout diagram in the manual was slightly confusing. Had to contact support to confirm UART pins.

Fast response time

Noticed the readings update very quickly when testing with incense. Great sensitivity for fine dust detection.

5 FAQ

Q: What is the default baud rate for UART communication?

A: The default baud rate is 9600 bps, but it can be configured via specific command sets.

Q: Is the fan included in the module housing?

A: Yes, the ZH06 series includes a built-in fan to ensure consistent airflow through the laser chamber.

Q: Can this be used for outdoor weather stations?

A: It is designed for indoor use. Exposure to rain or high humidity outside the operating range may damage the sensor.

Q: Does this require regular calibration by the user?

A: No, the module comes factory calibrated. Recalibration is not typically required during its standard lifespan.

Q: Can this sensor operate on 3.3V logic levels?

A: While the module runs on 5V power, the UART TX pin is 5V TTL. We recommend using a level shifter for 3.3V MCUs.
