Embodiment 1

[0023] Such as Figure 1-5 As shown, the miniature rapid body temperature sensing device includes a housing 1 and a temperature sensor 2. The housing is a closed housing containing a cavity inside, and the temperature sensor 2 is a thermal sensor with an error of less than 2% in the range of 32-45°C. Resistance, the error is preferably within 0.2-1%. The thermistor temperature sensor is arranged on the surface of the housing that is in contact with the object to be measured during use. The signal lead of the temperature sensor passes through the housing and is connected to the sensing signal transmission / output circuit 3 provided in the housing. The sensor signal transmission / transmission output circuit is provided with transmission / transmission signal output terminals for connection with external devices.

[0024] The temperature sensor in this embodiment is spherical, hemispherical, rice grain or water drop-shaped. The surface of the housing 1 that is in contact with the obje...

Embodiment approach

[0028] As a preferred embodiment: a single-chip computer is embedded in the sensor signal transmission / output circuit 3. The humidity sensor 5 and the temperature sensor 2 are connected to the signal input terminal of the single-chip computer through a resistance-capacitance transmission circuit or other forms of transmission circuits. The transmitted signal can be output by the communication interface of the computer.

Abstract

The invention relates to a miniature rapid body temperature sensing device comprising a shell and a temperature sensor. The shell is a closed shell and comprises an accommodating hollow cavity inside, the temperature sensor is a thermistor with error smaller than 2% at the temperature of 32-45 DEG C and is arranged on the contact surface between the shell and an object to be measured when the miniature rapid body temperature sensing device is used, a signal lead of the temperature sensor penetrates the shell to be connected with a sensing signal conversion / transmission output circuit arranged in the shell, and a conversion / transmission signal output terminal for being connected with an external device is arranged on the sensing signal conversion / transmission output circuit. The miniature rapid body temperature sensing device is high in measurement speed and sensitivity, small in size, low in manufacturing cost, durable, capable of measuring humidity and particularly applicable to measurement of vital signs such as human bodies.

Description

Technical field [0001] The invention relates to a high-precision body temperature detection technology, in particular to a miniature rapid body temperature sensing device that is applied to the human body or other requiring direct contact and rapid body temperature measurement. Background technique [0002] The temperature sensor is the earliest developed and most widely used type of sensor. The market share of temperature sensors greatly exceeds that of other sensors. At the beginning of the 17th century, people began to use temperature for measurement. Temperature sensor is the core part of temperature measuring instrument, and there are many kinds of temperature sensors with different functions. Nowadays, temperature sensors have also been used to measure human body temperature. For example, electronic thermometers that are widely used nowadays use temperature sensors to accurately and quickly measure human body temperature and are favored by consumers. One of the import...
