Geophones are a type of equipment that converts ground vibrations into electrical signals. The most widely used is petroleum exploration. It is also commonly used in ground crack detection, gas layer development, debris flow warning, and VSP logging. The core component in the geophone is the acceleration sensor, which can obtain information about the frequency and amplitude of the vibration by measuring the acceleration in the vertical direction of the vibration.
When using geophones for geological exploration, artificial earthquakes are usually required to generate vibration signals in the formation, and then the detectors with acceleration sensors are buried in different locations as required. The electrical signal converted by mechanical energy can be obtained by the acceleration sensor measuring the vibration measurement of the passing point. The signal is stored in the memory after being amplified and converted by the corresponding circuit, and the properties of the vibration propagated through the ground medium are obtained by analyzing the characteristics of the electrical signal. From this analysis, the formation properties and structural forms of different depths are judged, so as to preliminarily determine whether oil and oil storage conditions are available, and finally provide the location of drilling.
The SCA820-D03 accelerometer consists primarily of a high precision MEMS accelerometer component and a flexible SPI digital interface. The product uses VTI's advanced 3D-MEMS capacitive sensor technology, while the entire design, production and testing phases are required for high stability, high reliability and high quality, making the SCA820-D03 single-axis accelerometer work. Extremely stable output in the range (including full temperature zone, humidity and mechanical noise). In addition, the dual-row pin package ensures safe and reliable operation throughout the life of the SCA820-D03 accelerometer.
Neck bluetooth headset - a bluetooth headset with headphone cables or accessories running from the neck to the ear when wearing. It is a product developed in recent years.
Born: in order to solve the boring when running or control the exercise rhythm, many people choose to listen to music,however, experienced people all know that because of the swing in the process of exercise, the earphones are easy to fall off, which makes it difficult to run coherently and constantly ,under this circumstance, the bluetooth neckband headphones was designed.
Features:
1: There is no restrained from headphone cables.
2: In line with the development trend of headphones: From the perspective of the development trend of consumer headphones, bluetooth neckband headphones should be regarded as the general trend. Whether it is sports headset or head-worn headset, many manufacturers are vigorously developing bluetooth headset to occupy the market.
3: Not affected by audio interface
More and more flagship mobile phones are also trying to cancel the audio interface, which is the important reason for the generation of bluetooth neckband headset. As long as the device that supports bluetooth music play is ok, the audio interface will not be considered.
4: No burden when running
Sports neck hanging bluetooth headset is light and easy to wear, more convenient and fast storage, no knot, more relaxed entertainment sports, let you run zero burden.
5: Waterproof and sweat-proof are very important
When exercising, people will sweat a lot, which may cause some damage to the ears. The bluetooth neckband headphones adopts the IPX5 waterproof design, which is more suitable for sports scenes. Especially in summer, when sweat is easy to happen, it is necessary to use the bluetooth neckband headphones.
