Gas and Air Quality Sensor Products

Description

The Gas sensors provided below are Air Quality sensors that can measure dust, Volatile Organic Compounds (VOCs), and Carbon Dioxide (CO2).

Air quality sensors include the SGP30, SGP40, CCS811, and ENS160. The SGP30 outputs the Total Volatile Organic Compound (TVOC) reading and an equivalent Carbon Dioxide reading (eCO2) over I2CInter-Integrated Circuit. Also referred to as IIC or I²C.. The SGP40 is the next generation after the SGP30, but rather than giving TVOC/eCO2 values out like the SGP30, it provides the raw signal from the sensor is processed using their software algorithm to give an overall air quality value from 0 to 500. The CCS811 provides readings for equivalent eCO2 in the parts per million (PPM) and TVOC in the parts per billion (PPB). The ENS160 is the replacement for the CCS811, with multiple IAQIndex for Air Quality outputs (TVOC, eCO2, AQI).

Dust and Particulate Matter sensors detect very fine particles in air and are commonly used in air purifiers. They use laser scattering to radiate suspending particles in the air and collect the scattered light to obtain the light change with time. Some even have a microprocessor that calculates the particle concentration.

Adafruit 4649 Dust Sensor Module Kit - GP2Y1014AU0F with Cable

Package includes:

• 1x GP2Y1014AU0F Dust Sensor Module
• 1x 6-pin pig-tail cable for interfacing with the sensor easily
• 1x 150 ohm resistor
• 1x 220μF capacitor

+ About this item:

• The SHARP GP2Y1014AU0F Dust Sensor Module Kit particulate sensor uses an LED to bounce off of particles suspended in the air
• You need a fast GPIO toggle to trigger the measurements, for that reason it's only for use with Arduino or other non-interpreted languages. E.g. not for use with CircuitPython
• You only get an analog voltage output that tells you how dusty it is - higher voltage = dustier, ranging from 0 to 0.5 mg/m3.
• You need to power it from 5V - however the output voltage can be read by a microcontroller that's running on 3.3V (the analog output maxes out at 3.6V)
