Product description:

This module is a high-performance, high-precision module for detecting a variety of volatile gases such as benzene, formaldehyde, and toluene in the air. It can detect volatile gases above 0.1PPM in air, and the chip has fast response speed, more accurate data and small volume. Mainly used in home air quality testing, ambient air testing, range hood ventilation fans. Module measurement range: 0~1000PPM gas qualitative detection.

Instructions for use:

1. Power supply voltage: +5V

2. AOUT: The analog output, the voltage value corresponding to the amount of gas detected by the chip, the microcontroller can be directly connected using the ADC.

3. DOUT: Digital output, the result of comparing the output voltage values of AOUT and adjustable resistors. Output semaphores 0 and 1.

4. Adjust the adjustable resistance of the module. When the voltage of the adjustable resistor output is less than AOUT, DOUT will output a high level and the LED will be on. Otherwise, DOUT will output a low level and the LED will be off.

5. Variable resistance: 4K

6. Clean air voltage <1V

7. Response speed <5S

8. Working temperature: -10 degrees Celsius ~ 60 degrees Celsius,

9. Working humidity: 90% RH

10. Size: 1.5 mm X2.5 mm

Precautions for use of the module: When needed, the module needs to be warmed up for 3-5 minutes before making relevant measurements.
