Small infrared CO2 sensor safety switch (NDIR CO2 sensor safety switch)
During normal operation of the infrared CO2 sensor safety switch (NDIR CO2 sensor safety switch) S8-4B, the sensor tests the CO2 gas concentration in the environment every 30 seconds. When the CO2 concentration exceeds 8000 ppm, the sensor will issue an alarm signal. If any malfunction is detected, the error detection path will issue an alarm signal. The alarm filter will protect the sensor from false alarms caused by intermittent interference.
