The MTHO3A module based on MEMS gas-sensing elements is used to test ambient temperature, humidity, and harmful substance content in the air. Test data is communicated via I²C or UART interface. The MEMS element surface can be protected with a filter membrane. The air quality sensor module can select plug-in or SMT assembly as needed.
The semiconductor LD-VOC series air quality module adopts advanced semiconductor gas-sensing elements. This sensor has extremely high sensitivity to organic volatile gases such as formaldehyde, benzene, carbon monoxide, ammonia, hydrogen, alcohol, and cigarette smoke. The module is aged, debugged, and calibrated, featuring excellent consistency and high sensitivity.
The MCO01 electrochemical carbon monoxide module is a general-purpose, miniaturized module. It uses electrochemical principles to detect CO in the air, offering good selectivity and stability. Built-in temperature sensor for temperature compensation; features both digital and analog voltage outputs for ease of use. The MCO01 module combines mature electrochemical detection technology with sophisticated circuit design to create a general-purpose gas module. Mainly used in portable instruments, air quality monitoring equipment, air purifiers, fresh air ventilation systems, air conditioners, smart home devices, and other locations.
The electrochemical HCHO01 formaldehyde sensor uses a dual-channel structure and unique electrolyte packaging. It outputs HCHO, VOC, and TVOC simultaneously with built-in digital temp/humidity sensors.
