MQ-135 Gas Sensor

Gravity: Analog Infrared CO2 Sensor is a high precision analogue CO2 sensor. It measures CO2 content in the range of 0 ... 5000ppm and is compatible with all devices with ADC function. DFRobot SEN0219

Gravity: UART Infrared CO2 Sensor is a high precision CO2 sensor. It uses the UART interface for communication. It allows to measure CO2 content in the air in the range of 0 ... 50000ppm. DFRobot SEN0220

The sensor is designed for indoor air quality testing. The main gas detected is carbon monoxide, alcohol, acetone, thinner, formaldehyde and other slightly toxic gases. It is compatible with 5V and 3.3V power supply. Seeed Studio 101020078

MH-Z16 carbon dioxide sensor with Grove connector. It communicates via the UART interface. Seeed Studio 101020067

Gravity: Formaldehyde (HCHO) Sensor is a module for measuring the concentration of formaldehyde (methane) in the air. It can be supplied with voltage in the range of 3.3 ... 6V. DFRobot SEN0231

Digital gas sensor solution that senses a wide range of Total Volatile Organic Compounds (TVOCs), including equivalent carbon dioxide (eCO2) and metal oxide (MOX) levels, intended for indoor air quality monitoring in personal devices such as watches and phones, but we’ve put it on a breakout board so you can use it as a regular I2C device. SEN-14193

The module allows the detection of volatile organic compounds (VOC) in the air, based on Winsen\'s WSP2110 system. Allows for detection in the air; formaldehyde (HCHO), methane, benzene, toluene, alcohol, etc. The sensor output is an analog signal. Seeed studio 101020001
