  • Page 2 Technical Parameters Working Voltage 5 VDC ± 0.2 V Working Current <150 mA Gas Detection Detection Concentration 10  1000 PPM (O Zero Voltage 3.5~4.5 V (This voltage is output without ozone) Preheating Time Not less than 2 hours, longer preheat time, more stable sensor Response Time >3 sec Recovery Time...
  • Page 3 Notes Confirm the polarity and the voltage of the power supply before powering ON the sensor. The analog output of this module is non-linear. When connect to microcontroller, it should be connected to ADC interface of the microcontroller. The relationship between the resistance ratio and the concentration is a logarithmic relationship. For more info on typical sensitivity curve, check MQ131 Probe on internet.
