Problems solved by technology

[0007] Since the sensor needs to send signals to the background equipment that is far away, the size of the antenna needs to be larger to meet the requirements of the wireless signal transmission distance, which leads to a larger sensor size
[0008] If the volume of the sensor needs to be reduced, the volume of the antenna needs to be reduced, but the reduction of the antenna volume will affect the transmission distance of the wireless signal emitted by the antenna
And, because the metal casing of the button battery has the effect of attenuating the wireless signal sent by the antenna, the existing miniature smart sensor also arranges the antenna at a position far away from the battery, resulting in a large distance between the antenna and the battery, thereby making the miniature smart sensor The size of the sensor is too large

Embodiment Construction

[0022] The miniature smart sensor of the present invention is used in security products of the Internet of Things system to detect movement signals or position signals of objects, and to send the detected signals wirelessly.

[0023] see figure 1 and figure 2 , the miniature smart sensor of the present invention has a housing, the housing includes an upper cover 10 and a bottom cover 15, the upper cover 10 includes an upper end face 11 positioned at the uppermost end of the miniature smart sensor and a peripheral wall 12 extending downward from the periphery of the upper end face 11, the bottom The cover 15 has a lower end surface 16 located at the lowermost end of the miniature smart sensor and a peripheral wall 17 extending upward from the periphery of the lower end surface 16 . After the upper cover 10 and the bottom cover 15 are fastened together, a complete shell is formed. The shell is in the shape of a flat cylinder, that is, the height of the cylinder is smaller than...

Abstract

The invention provides a micro intelligent sensor which comprises a shell, wherein the shell is internally provided with a circuit board as well as a battery which are arranged in a stacked mode, wherein the circuit board is provided with an antenna; and on the projection of the circuit board on a plane, the antenna is positioned at the outer side of the battery, and the distance between an emitting end of the antenna and the center of the battery is greater than the distance between a feed end of the antenna and the center of the battery. The micro intelligent sensor provided by the invention is small in volume; and the influence on a wireless signal emitted by the antenna by a shell of the battery is low, and the communication quality of the micro intelligent sensor and other devices is ensured.

Description

technical field [0001] The invention relates to the field of sensors, in particular to a miniature smart sensor for the Internet of Things. Background technique [0002] Miniature smart sensors should be extremely widespread in modern Internet of Things technology. They can be used as signal detection and emission devices in Internet of Things security products to detect vibration signals of specific areas or specific objects or displacement signals that reach the trigger threshold, and will detect The signal is transmitted wirelessly. After the background receiving device in the Internet of Things system receives the signal of the micro smart sensor, it processes the signal and provides it to other demanders in the Internet. [0003] Existing miniature smart sensors usually have a housing, in which a circuit board and a battery are arranged, the circuit board is provided with a chip, a detection circuit and an antenna, the battery supplies power to the chip, the detection ...
