Infrared carbon dioxide sensor MH-Z14A

Description:

The MH-Z14 carbon dioxide gas sensor is a universal smart small sensor that uses the non-dispersive infrared (NDIR) principle to detect CO2 present in the air. It is a high performance sensor with good selectivity and no oxygen dependence. 

Features:

• High sensitivity, high resolution, low power consumption
• Various output methods: UART, analog voltage signal, PWM waveform
• Fast response time
• Temperature compensation, excellent linear output
• Excellent stability
• Anti-water vapor interference
