Product Specification

Overview:

HT8101 is a digital carbon dioxide sensor based on non-dispersive infrared absorption (NDIR) method. Using non-dispersive infrared (NDIR) method to detects the presence of CO2 in the air, with good selectivity, no oxygen dependence, and long lifetime; Built-in temperature compensation; It also has serial port output, analog output and PWM output, very convenient to use. The sensor is a high-quality sensor combining mature infrared absorption gas detection technology with precise optical circuit design and sophisticated circuit design.
