CO2 Sensor
Detection of CO2 in Air Using Non Dispersive Infrared (NDIR) Principle
Application:
Heating, Ventilation, and Refrigeration EquipmentProduct characteristics:
High sensitivity, low power consumptionDescription
The TX-Z19E carbon dioxide gas sensor (hereinafter referred to as the sensor) is a universal intelligent small sensor with two products: pins and terminals. It uses the principle of non dispersive infrared (NDIR) to detect CO2 in the air, and has the characteristics of good selectivity, oxygen independence, and long service life; Built in temperature compensation; Simultaneously equipped with serial port output and PWM output, convenient to use. This sensor is a high-performance sensor that combines mature infrared absorption gas detection technology with precision optical path design and sophisticated circuit design.
