Changes in ascorbate content and its enzymatic utilization pattern were studied in embryonic axes and cotyledons of sal seeds undergoing rapid loss of viability, at ambient conditions. Ascorbate levels were significantly higher initially in the embryonic axes (0.32 mg/g fresh weight) and cotyledons (0.21 mg/g fresh weight) of freshly mature, relatively hydrated (42.2% moisture content) and 100%...

With the research of the wireless sensor network technology, some wireless underground sensor network nodes and a sink node based on embedded technology and RF technology were designed innovatively. Wireless underground sensor network node consists of sensor, the processor, wireless RF module and power module; here, processor using MSP430 microcontroller, RF modules adopting nRF905 communicatio...

A laboratory experiment was conducted with bean seeds kept in three different containers viz. tin pot, poly bag and jute bag and stored at room temperature and RH for three months in the Laboratory of Agronomy Department, Sher-eBangla Agricultural University to study their storage behavior, germination percentage and quality. The seed of jute bag came to the contact with air and their moisture ...

Moisture content is an important factor in corn breeding and cultivation. A corn breed with low moisture at harvest is beneficial for mechanical operations, reduces drying and storage costs after harvesting and, thus, reduces energy consumption. Nondestructive measurement of kernel moisture in an intact corn ear allows us to select corn varieties with seeds that have high dehydration speeds in ...

This paper presents a pair of portable wireless nodes for smart agricultural system to control and monitor the parameters based on Internet Things (IoT). utilizes low-cost communication through an nRF24L01 module between sensor node controller node. The is placed area with Li-Ion battery as power supply, while at monitoring station. On node, there YL-69 soil moisture DS18B20 temperature sensor,...

The paper summarize that moisture sensor based on microstrip patch antenna. Microstrip patch sensors have become useful and widely used in every fields such as agricultures, industrials, food products, medicals communication etc. It have been more useful for detecting i.e., broken rice detection, Impurities detection in water, Soil moisture measurement, Rice Grain moisture, Rice quality detecti...

This work deals with the fabrication, prototyping, and experimental validation of a fiber optic thermo-hygrometer-based soil moisture sensor, useful for rainfall-induced landslide prevention applications. In particular, we recently proposed a new generation of fiber Bragg grating (FBGs)-based soil moisture sensors for irrigation purposes. This device was realized by integrating, inside a custom...

A novel fiber-optic sensor assembly for continuous monitoring of moisture over extended subsurface environments, such as road embankments, wall backfills, and landfills is presented. This sensor meets the requirements of subsurface monitoring by distributed measurements over linear positioning of a single fiber. The sensor assembly is composed of a communication optical fiber and a hydrophilic ...

Real-time non-invasive moisture content sensing techniques are needed for online moisture measurement and control in food products. In this investigation, a dielectric spectroscopy based system is used for moisture determination in cookie dough. Experiments were conducted with a concentric ring dielectric sensor in the frequency range from 10 Hz to 10 kHz. The system is calibrated based on a li...
