This Fermion: ENS160 Air Quality Sensor, based on ScioSense’s new ENS160 sensor chip, is specifically designed for indoor air quality monitoring and offers detection of multiple IAQ data(TVOC, eCO2, AQI).

The innovative TrueVOC™ technology combines the metal oxide(MOX) technology that brings this sensor superior accuracy, fast response, anti-interference, etc. With intelligent on-chip algorithms, the ENS160 can directly output rich and easy-to-understand environmental data. Preheat the sensor 3 minutes before use then you can obtain accurate data more quickly. What’s more, the built-in automatic baseline correction algorithm ensures the long-term stability of the sensor.

AOX4000 is an oxygen sensor that measures the partial pressure of oxygen in the environment based on the principle of fluorescence quenching. The sensor has a built-in air pressure sensor, which can directly output the values of ambient air pressure, oxygen partial pressure, and oxygen concentration, which is convenient for users to read data intuitively. Compared with electrochemical sensors, AOX4000 has longer life. Due to the temperature compensation function, no additional compensation system is required. AOX4000 is very stable and environmentally friendly, does not contain lead or any other harmful substances.

Features:

1. High precision, temperature compensation
2. No Drift, Low Power Consumption
3. Long life, fast response, fully calibrated
4. Lead-free, RoHS compliant
5. Digital output oxygen partial pressure, atmospheric pressure

Package Includes:

1 x Fluorescent oxygen sensor AOX4000

TGS 3870-F00 is a micro-bead type semiconductor gas sensor for the detection of both methane and carbon monoxide. Using a micro-bead gas sensing structure, both methane and carbon monoxide can be detected with a single sensor element by periodic application of two different heater voltages (high and low). Miniaturization of the gas sensing bead results in a heater power consumption of only 38mW (average).

TGS 3870-F00 has low sensitivity to alcohol vapors (a typical interference gas in the residential environment) and has high durability, making the sensor ideal for consumer market gas alarms.

Note: For more technical details go through Datasheet in the attachment section

Features:

1.  Miniature size and low power consumption
2.  High sensitivity and selectivity to both
   methane and carbon monoxide (CO)
3.  Low sensitivity to alcohol vapor
4.  Long life and low cost

Package Includes:

1 x Figaro TGS3870 Methane/Carbon Monoxide Sensor

Healthy living starts with healthy air! As the most basic part of life, air is attracting more and more attention these years, for example, PM2.5, smog, etc. Keeping an eye on the quality of the air we breathe is becoming quite important.

This Air Quality Monitor introduced by DFRobot provides you with the measurements of PM10, PM2.5, and PM1.0 as well as temperature and humidity. It works well with devices like Arduino, STM32.Based on the principle of laser scattering, this sensor continuously collects and calculates the number of suspended particles of various sizes in the air per unit volume, which is particle concentration distribution, and then converts to mass concentration. At the same time, a temperature & humidity integrated sensing chip is embedded in the module for accurately detecting the temperature and humidity.

In a word, this air quality sensor combines the particle concentration value, temperature, and humidity monitoring functions onto one module, and outputs the relevant data frames via UART. It can be embedded in various instruments and equipment related to air quality monitoring and environmental air improvement to provide timely and accurate environmental parameters.

Features:

1. Laser scattering principle, accurate measurement
2. Zero false alarm rate
3. Real-time response and support continuous acquisition
4. Minimum recognizable particle size 0.3μm
5. Brand-new patented structure, six-sided all-around shielding, stronger anti-interference performance
6. The direction of the air inlet and outlet is optional, and wider application ranges
7. Real-time output temperature and humidity data

Package Includes:

1 x DFRobot Air Quality Monitor (PM 2.5, Formaldehyde, Temperature & Humidity Sensor)

Are you searching for a temperature sensor having high accuracy? Then, the Grove Temperature Sensor v1.2 is perfect for you. It uses a thermistor as a form of resistance value to alter the Vcc. The resistance of a thermistor will increase when the ambient temperature decreases. Its this characteristic that we use to calculate the ambient temperature. Depending on the temperature measured, it supplies an analog signal from 0 to 5 Vcc. The detectable range of this sensor is -40 to 125C and the accuracy is 1.5C.
