상품 특징
- This gas sensor module is based on the MQ-135 semiconductor sensing element and is designed to detect changes in air composition. It responds to gases such as ammonia, benzene, alcohol vapor, and smoke by varying its internal resistance, enabling concentration-related signal output.
- Provides both analog output and digital threshold output for flexible system integration. The analog signal allows continuous monitoring of gas concentration changes, while the digital output switches state when the preset threshold level is exceeded.
- Operates on a 5V DC power supply and includes a built-in heating element required for proper sensor operation. A short preheating period is recommended before stable measurement to allow the sensing element to reach operating temperature.
- An onboard potentiometer enables adjustment of the digital output threshold. This allows configuration of trigger sensitivity depending on environmental conditions and application requirements in embedded control systems.
- Compact PCB layout with clearly labeled VCC, GND, AO, and DO pins allows straightforward wiring to microcontrollers. Suitable for environmental monitoring experiments, air sampling projects, and electronics development applications.
