Four-channel temperature and humidity microwave scanning radiometer

Temperature and humidity is the important physical quantities within the measurement field. Separated temperature and humidity sensors commonly used are nonlinear output and less consistently, resulting that temperature and humidity measurement methods are relatively complex. This paper presents a multi-channel temperature and humidity monitoring system with SoC MCU. It consists of microprocessor, temperature and humidity sensors, display circuit, keyboard input module, communication interface module, voice playback module and other components. The digital sensor SHT21 collects temperature and humidity information and send into SPCE061A MCU. The system has real-time LCD display and voice broadcast function. If the temperature and humidity exceed the set range, an alarm will be given. Microcontroller transfers measurement data to the computer through USB-UART converter circuit with SPCP825A and MAX232 chips. Real-time temperature and humidity changes are dispalyed and recorded on computer. The system has a simple structure, low power consumption, cheap cost, small volume and good prospects.

To achieve complete microstructural characterization of self-aggregating systems, one needs direct images in addition to quantitative information from non-imaging, e.g., scattering or Theological measurements, techniques. Cryo-TEM enables us to image fluid microstructures at better than one nanometer resolution, with minimal specimen preparation artifacts. Direct images are used to determine the “building blocks” of the fluid microstructure; these are used to build reliable physical models with which quantitative information from techniques such as small-angle x-ray or neutron scattering can be analyzed.To prepare vitrified specimens of microstructured fluids, we have developed the Controlled Environment Vitrification System (CEVS), that enables us to prepare samples under controlled temperature and humidity conditions, thus minimizing microstructural rearrangement due to volatile evaporation or temperature changes. The CEVS may be used to trigger on-the-grid processes to induce formation of new phases, or to study intermediate, transient structures during change of phase (“time-resolved cryo-TEM”). Recently we have developed a new CEVS, where temperature and humidity are controlled by continuous flow of a mixture of humidified and dry air streams.

An investigation had been done to Tetragonula (Tetragona) sp nest at Indralaya, South Sumatra to describe the Tetragonula sp nest that use streetlight pole as nest medium during April - May 2019. Purpossive sampling is used to select the target nest. Two streetlight pole found be used by Tetragonula sp as their home. The coordinate of location, heght from ground surface, diameter of streetlight pole, air temperature and humidity, and floral species around nest, were noted. Spot coordinate are S 30 14’ 19.2498’’ and E 1040 39’ 15,3288’’ ; 1,5 m above the ground surface, 12 cm diameter pole, highest air temperature was 35 o C at daylight (April and May 2019), 80 – 90 % humidity at April-May 2019; which Switenia macrophyla, Hevea brasiliensis, Zea mays, and Citrullus lanatus floral species are planted around. Air temperature in the pole is very high, around 40 0 C during daylight.
