Description
Affiliated technical field
The utility model relates to a kind of measurement of bldy temperature light show pen, belongs to the body temperature fields of measurement.
Background technology
At present, being used to carry out the overwhelming majority that human body temperature measures is to use the glass clinical thermometer, and mercury is equipped with in this glass clinical thermometer inside, uses frangiblely, dangerous, and reaction velocity is slow.In fact, the purpose of people's take temperature wonders exactly whether measured people generates heat, and whether if what degree heating generates heat to, it is just passable to need to go to a doctor.
Summary of the invention
The purpose of this utility model provides a kind of measurement of bldy temperature light show pen, and when measured human temperature is normal, green LED is luminous, and when measured people's heating, different the degree of heat is just with the lumination of light emitting diode of different colours.
The purpose of this utility model is achieved in that with thermistor makees temperature sensor, do voltage follower and voltage comparator with integrated operational amplifier, by thermistor. integrated operational amplifier. three terminal regulator. the light emitting diode of different colours. resistance and associated electrical original paper are formed measurement of bldy temperature light show pen circuit, this circuit is made up of a voltage follower and seven voltage comparators, it is characterized in that: at the light emitting diode of each voltage comparator output terminal of forming by integrated operational amplifier series connection different colours, after connecting, the out-phase input end of voltage comparator connects the output terminal of voltage follower, the in-phase input end of voltage comparator connects the positive pole of power supply by resistance, the in-phase input end of one termination voltage follower of thermistor, other end ground connection.Thermistor MF51 type negative temperature coefficient, integrated operational amplifier uPC324 model, three terminal regulator 78L06 model.
Since adopt technique scheme, a kind of measurement of bldy temperature light show pen, and the advantage that is had is: safe and reliable, it is fast to measure reaction velocity, observes intuitively, and cost is not high yet.
