Features:
1ALARM OUTPUT FUNCTION: The MTP50 module supports alarm output with the Alarm OC pin. The Alarm OC pin is configured as an open drain output mode and requires an external pull up resistor for operation. 2ACCURATE CO2 DETECTION: When the measured CO2 concentration exceeds 1000PPM, the Alarm OC pin outputs a high level. Conversely, when the measured CO2 concentration is below 80PPM, the Alarm OC pin outputs a low level. 3ERROR DETECTION: In the event of a module error, the Alarm OC pin will remain at a high level, alerting users to potential malfunctions. 4NDIR TECHNOLOGY: The MTP50 A adopts non dispersive infrared (NDIR) principle for detecting carbon dioxide in the air. It offers high sensitivity, low power consumption, and excellent stability. 5WIDE APPLICATION RANGE: This CO2 sensor is suitable for various applications, including AC equipment, air quality monitoring devices, fresh air systems, air purification equipment, smart homes, and air testing devices in schools.
