and wireless technology.The main objective of this system is sensing the climate parameters,such as temperature,humidity,and existence of some gases,based on the sensors.The captured values can then be sent to remote applications or databases.Afterwards,the stored data can be visualized in graphics...
[Eunjae] is using an Arduino Nano, a 128×64 OLED screen, and a battery inside of a rugged waterproof case. He also added an ADS1115 16 Bit DAC between the oxygen sensor and the Arduino for fast and accurate readings over I2C. With the hardware assembled, calibrating the device is as...
Also, the chamber can contain gases inside to participate in the corrosion reaction, which is desired in some corrosion studies26. 3.5% NaCl solution is commonly used in the metal corrosion experiment; for our experiment, we adopt this 3.5% NaCl solution8. During experiments, a peristaltic pump...
The following examples for environmental sensors concentrate on CO2 and CH4, but the design considerations also account for other MIR-active gases. Most CO2 sensor systems include one IR source and two detectors, one equipped with a filter at 4.3 μm and one at around 4 μm for reference [...
Environmental sensing has been widely used to detect various quantities like temperature, humidity, different gases, light intensity, pressure, chemical and biological contaminations, etc. For basic environmental sensing, the most important requirements for any type of sensor are reasonable measurement ...
According to the operation of the designed chip, MEMS can be divided into different categories. It can be used to execute the sensing for measuring, monitoring and detecting hazardous gases. Another classification is using MEMS as action type device which act upon the body or with the body mate...
The use of tracer gases is a common approach for acquiring quantitative data on ventilation rates; however, it may not fully represent aerosol behavior. Recently several researchers utilized tracer aerosols to evaluate air quality and aerosol propagation in indoor environments33,34. Motivated by ...
