1. HiLetgo® MQ-135 MQ135 Air Quality Sensor Hazardous Gas Detection Module For Arduino AVR
- Main chip: LM393,MQ-135 gas sensor
- With high sensitivity and good selectivity for air quality, harmful gas detection.
- With the DO switch signal (TTL) output and AO analog signal output
- Useing of high-quality double-panel design, with power instructions and TTL signal output instructions
- TTL output valid signal is low. (When the output low signal light, can be directly connected to the microcontroller or relay module)
MQ-135 sensor introduction:
The gas sensitive material used with the MQ135 gas sensor is tin dioxide (SnO2), which has a lower conductivity in clean air. When contaminated gas is present in the environment
where the sensor is located, the conductivity of the sensor increases as the concentration of contaminated gas in the air increases. A simple circuit converts the change in conductivity into an output signal that corresponds to the gas concentration.
The MQ135 sensor is highly sensitive to ammonia, sulphides and benzene vapors and is also ideal for smoke and other harmful monitoring. This sensor can detect a variety of harmful gases, is a low-cost sensor for a variety of applications.
It is suitable for the detection of harmful gases such as ammonia, aromatics, sulfides, benzene vapor, smoke and other harmful gas detection devices, gas sensor testing range of concentration: 10 to 1000ppm
Input voltage: DC5V Power consumption (current): 150mA
DO output: TTL digital quantities 0 and 1 (0.1 and 5V)
DO output: TTL digital quantities 0 and 1 (0.1 and 5V)

8. Adafruit CCS811 Air Quality Sensor Breakout – VOC and eCO2
Breathe easy – we finally have an I2C VOC/eCO2 sensor in the Adafruit shop! Add air quality monitoring to your project and with an Adafruit CCS811 Air Quality Sensor Breakout. This sensor from AMS is a gas sensor that can detect a wide range of Volatile Organic Compounds (VOCs) and is intended for indoor air quality monitoring. When connected to your microcontroller (running our library code) it will return a Total Volatile Organic Compound (TVOC) reading and an equivalent carbon dioxide reading (eCO2) over I2C. There is also an onboard thermistor that can be used to calculate the local ambient temperature.
The CCS811 has a ‘standard’ hot-plate MOX sensor, as well as a small microcontroller that controls power to the plate, reads the analog voltage, and provides an I2C interface to read from.
