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 MTHO3A1 temperature and humidity sensor module, based on a MEMS gas-sensing element, is used to measure ambient temperature and humidity as well as the concentration of harmful substances in the air. Measurement data are transmitted via I²C or UART interfaces. The surface of the MEMS gas-sensing element can be protected with a filter membrane, and the air quality sensor module can be assembled using either a plug-in board or SMT mounting, depending on requirements.
