MQ138 VOC (Mellow, Benzene, Aldehyde, Ketone, Ester) Volatile organic compounds (abbreviation VOCs or VOCs according to volatile organic compound [s]) is the collective term for organic, ie carbon-containing substances that evaporate easily (or are volatile) at low temperatures (eg room temperature) as gas. The gas methane, CH4, is often not included, sometimes explicitly excluded by the abbreviation NMVOCs (non-methane volatile organic compounds).
Grove – HCHO Sensor: The Grove – HCHO sensor is a semiconductor VOC gas sensor. It uses the VSP sensor WSP2110, whose conductivity changes with the concentration of VOC gas in air. With a circuit, the conductivity can be converted into an output signal that corresponds to the gas concentration. This sensor has a very high sensitivity and stability, it can detect the gas with a concentration of up to 1 ppm. It can be used to detect toluene, methane, benzene, alcohol, acetone, etc. This product can be used to detect the presence of harmful gas in the home environment. It can be a good helper to improve indoor air quality.
Dust Sensor This dust sensor gives a good indication of air quality in an environment by measuring the dust concentration. Particle content (PM level) in the air is measured by counting the time of low pulse occupancy (LPO time) in a given unit of time. The LPO time is proportional to the PM concentration. This sensor can provide reliable data for air purification systems; it reacts to PM with a diameter of 1 μm.
Airquality Sensor The sensor has been developed for indoor air quality testing. Mainly the sensor can detect carbon monoxide, alcohol, acetone, thinner, formaldehyde and other slightly toxic gases. It is compatible with a 5V and 3.3V power supply.
Multichannel Gas Sensor Grove – Multichannel Gas Sensor is an environmental sensor with a built-in MiCS-6814 that can detect many harmful gases, and three gases can be measured simultaneously due to its three channels, so it can help you maintain that concentration to monitor more than one gas.
This sensor belongs to the Grove system and you can connect it to the base shield and work with Arduino directly without jumper wires. The interface of this is I2C, so plug it into the base plate’s I2C connector, then you can start working it Detectable Gases: Carbon Monoxide (CO), Nitrogen Dioxide (NO2), Hydrogen (H2), Ammonia (NH3), Methane (CH4) etc.
Grove gas sensor (O₂) Grove gas sensor (O₂) is a type of sensor for checking the oxygen concentration in air, which is based on the principle of the electrochemical cell to the original work. You can clearly see the current oxygen concentration by outputting voltage values that are proportional to the oxygen concentration, and refer to the linear characteristic of the oxygen concentration. It is very suitable for the detection of oxygen concentration in environmental protection.
CO2 sensor module The Grove – CO2 sensor module is an infrared CO2 sensor with high sensitivity and high resolution.

Grove – RTC According to the name, it is easy to know that the Grove – High Precision RTC is a more accurate real time clock compared to Grove – RTC with the regular clock chip DS1307. The heart of Grove – High Precision RTC is PHILIPS PCF85063TP, a CMOS chip optimized for low power consumption. The typical current may be below 1.2uA in certain environments. All addresses and data are transmitted serially via the two-line bidirectional I2C bus, which has a maximum speed of 400 kbit / s. An offset register allows for fine tuning of the clock, and the register address is automatically incremented after every byte of data read or written. The Grove – High Precision RTC could be one of the most accurate and low-consumption RTCs you can get.
