MQ 135 Sensor, Air Quality Detection Sensor Module MQ 135 Sensor Introduction: The MQ135 gas sensor uses tin dioxide (SnO2), a gas-sensitive material with low conductivity in clean air. When polluted gases are present in the sensor's environment, the sensor's conductivity increases as the concentration of the pollutant increases. A simple circuit converts this conductivity change into an output signal corresponding to the gas concentration. The MQ 135 sensor is highly sensitive to ammonia, sulfide, and benzene vapors, and is also ideal for monitoring smoke and other hazardous gases. This sensor can detect a wide range of harmful gases and is a low-cost sensor suitable for a variety of applications. Module Applications: Used as a hazardous gas detector for homes and the environment, suitable for detecting harmful gases such as ammonia, aromatic compounds, sulfides, benzene vapor, and smoke. The gas sensor has a test concentration range of 10 to 1000 ppm. Module Features: -...

1500 Watts Boost Step UP Converter Module Module Name: 1500W Boost Step Up Converter Module Module Type: Non-isolated Boost Module (BOOST) Input Voltage: DC 10-60V Input Current: 10-30V input voltage, 30A 31-60V input voltage, 2A Quiescent Current: 15mA (When increasing from 12V to 20V, the quiescent current will increase slightly with higher output voltages.) Output Voltage: 12-90V continuously adjustable (The default output voltage is 19V for shipment. Please specify if a different voltage is required. Multimeters are available for adjustment.) 12-90V fixed output (for bulk orders) Output Current: 20A maximum.
