The system is mainly used for long-term, real-time monitoring of the body temperature of small animals, and is particularly suitable for scientific research and medical fields.

[0040] The shell of the temperature measuring capsule 1 is made of PEEK material with good biocompatibility. It is cylindrical with a diameter of 7.5mm and a length of 23mm. The two ends are rounded. It can also be designed as an ellipsoid or a sphere to meet different experimental needs. It has a waterproof function. A battery, a micro PCB circuit board, an LED light and a photosensitive sensor are arranged inside the shell. The battery is a rechargeable battery, generally a lithium-ion battery, which supports wireless charging to meet the needs of long-term continuous use.

[0041] The micro PCB circuit board is equipped with a low-power Bluetooth chip, a high-precision temperature sensor and a control chip.

[0042] A timer is provided in the control chip to control the working state of the temperature measuring capsule 1. The temperature measuring capsule 1 realizes the light activation function through the LED light and the photosensitive sensor. The user can activate the capsule by continuously illuminating it with the fill light of the mobile phone for 10 seconds.

[0043] The control chip can use a low-power algorithm to achieve a standby current of 100nA and an average operating current of 10uA, thereby further reducing power consumption.

[0046] Through the above structure, the wireless temperature measurement capsule 1 system of the present invention can realize high-precision, long-lasting real-time monitoring of the body temperature of small animals, and is easy to operate without affecting the normal activities of the animals, providing an effective tool for scientific research and medical treatment.

[0047] Embodiment 2:

[0048] This embodiment provides a high-precision, long-life wireless temperature measurement capsule 1 system based on low-power Bluetooth. The system is particularly suitable for long-term, continuous temperature monitoring of small animals in clinical and laboratory environments.

[0049] The temperature measuring capsule 1 is designed with biocompatible PEEK material and is in the shape of a cylinder with a diameter of 7.5 mm and a length of 23 mm, with rounded corners at both ends to reduce discomfort to the animal. In addition, the capsule can also be designed into an ellipsoid or sphere according to specific application requirements.

[0050] The capsule contains a miniature PCB circuit board, which is equipped with a low-power Bluetooth chip, a high-precision temperature sensor, and a control chip. The control chip has a built-in timer to manage the working status and sleep cycle of the capsule.

[0054] The micro PCB further includes a microprocessor and a memory module for processing and storing temperature data. These data can be displayed and analyzed in real time through a supporting mobile application, providing users with convenient data management and monitoring functions.

[0055] Through the above technical solution, this embodiment realizes a wireless temperature measurement capsule 1 system that is easy to operate, has stable performance, and has a wide range of applications, providing strong technical support for scientific research and medical fields.

[0056] The specific working principle of this utility model:

[0057] The capsule is in dormant mode at ordinary times. When it is needed, it can be activated by light (the built-in fill light of the mobile phone can be used). To prevent false triggering, it needs to be activated by continuous lighting for 10 seconds. Wait for the LED to change from slow flashing to fast flashing 5 times, which means it is activated successfully.

[0058] The wireless temperature measurement capsule 1 is a high-performance micro-body temperature detection system, which consists of three parts: capsule, receiver 3 and desktop software. The capsule body has a diameter of 7.5mm and a length of 23mm. It can be sent into the gastrointestinal tract of animals to detect core body temperature, and can also be implanted subcutaneously for long-term monitoring. The shell is made of PEEK material, which has good biocompatibility and does not produce rejection reaction. The capsule transmits data wirelessly to the receiver 3 connected to the computer every 5 seconds through Bluetooth communication. The desktop software will display the temperature data in real time and record and archive it. The capsule body is a micro PCB circuit board with a size of only 5*9mm, equipped with a low-power Bluetooth chip and a high-precision temperature sensor. The shell is made of peek material. After testing, the rejection reaction in the animal body is extremely small, and it can accurately measure the animal's body temperature in real time and send the data through low-power Bluetooth.

[0059] The receiver 3 can receive data sent by multiple capsules through the low-power Bluetooth protocol, process the data in real time, and then send it to the desktop software.

[0060] In addition, the control system can be written in Rust language on the computer desktop processing part, so that more capsules can be displayed synchronously and saved in the database. On the desktop, users can view the recorded temperature curve in real time, and users can also select the required data to save.

[0061] When long-distance transmission is required, a repeater 2 is provided. It can be placed within 2m of the capsule to send the signal to a receiver 3 up to 10m away. The signal sent by the capsule is received by the receiving antenna and sent to the distant receiver 3 through the transmitting antenna to realize data relay.

[0062] The capsule is in dormant mode at ordinary times. When it is needed, it can be activated by light (the built-in fill light of the mobile phone can be used). To prevent false triggering, it needs to be activated by continuous lighting for 10 seconds. Wait for the LED to change from slow flashing to fast flashing 5 times, which means it is activated successfully.
