Why is there no temperature in the body when I am angry?

How so? Impossible!

Your topic is an analog thermostat, which only requires two states, on and off, no requirements for PID temperature adjustment, no precision requirements, no linear scale, very simple.

The basic idea is that the temperature sensor can use a thermistor, a thermocouple, and the thermocouple outputs a temperature-related voltage, which needs to have a cold junction reference point, which is a little more troublesome. Semiconductor thermistors and platinum thermistors, the temperature is not linear with the resistance. The most trouble-free is to use the AD590 as a temperature sensor, just 2 legs, the temperature and the current are linearly related, every 1 (1K), the V+ termination of the current change is 5V, the V- termination is 1K sampling resistor, and the other end of the resistance is grounded.

The resistors at each end give a voltage that is linearly related to temperature, 1mV.

This voltage is amplified 10 times by an op amp in the same phase, and is fed to one input of the voltage comparator, and the other input end of the comparator is connected to the slide arm of a 10K sliding rheostat, one end of the sliding rheostat is connected to ground, and the other end is connected to a 20K resistor and then connected to 5V for setting the temperature. There are two comparators, one for setting the upper temperature limit and the other for setting the lower temperature limit, which determines the heater switch and the fan switch. Relays are driven with transistors, and relays are used to drive heaters and fans.

The output of the two comparators can be logically processed first, such as turning on the fan when the heating is turned on, and turning off the heating when the fan is turned on.

Op amps are the cheapest quad op amps LM324, dual op amps LM358, single op amps UA741, OP07 are all OK, and the comparators can be made with op amps or with a dedicated dual comparator LM393. The specific circuits can be found on the Internet or in the model book, or on the datasheet of these devices.

Do it in blocks and connect them together for debugging.

It's cold. It may also be because of the cold body, and the personality is not very cheerful and lively.

Lack of exercise, so do I. It always feels cold.

1. From a physiological point of view, this is impossible, because your heart is in the body, then the temperature is degrees. If the body temperature is lower than 37 degrees, then it cannot function normally.

2. From an emotional point of view, you can survive. Just like the walking dead.

3. From the perspective of friends, I advise you, your heart is cold, you can revisit. A short cooling is fine. But don't get addicted.

Traditional Chinese medicine says: When people are angry, it will cause a lot of damage to the body, and girls are prone to nodules.

Resist! Extremely excited! Brain congestion! Hormone secretion is crazy! Pupils dilated! Very focused!

What effect does anger have on the body? Let's find out.

Anger will make people's ** grow old faster, if there are some diseases such as heart disease, it will aggravate their own condition, and even die directly if it is serious.

The effect of anger on the body should not be obvious, but long-term psychological anger should have great disadvantages.

In fact, when people are angry, their heartbeat will increase, and people's emotions will be greatly inhibited, which will have a lot of bad effects on the body.

Remember one thing, people live in the world, don't get angry, this is a very irrational behavior, it will have a great impact on the body.

People will age very quickly when they are angry, because many people say that if they are angry, they will speed up the aging process, which is also very bad for the body.

If you are in a bad mood, it will also have a great impact on your health, and it may cause some neurological diseases.

When people are angry, it will have a greater impact on their emotions, and people who are in a bad mood are often in a bad state when eating or in daily life, so it is better to be less angry.

When you are angry for an hour, you will grow old quickly, and when the human body is angry, the burden on the brain will increase, and the nerves will be in a tense state, and being too emotional is not good for the people around you

The blood will be over-dilated, the head is hot, it is easy to cause excessive pressure on the heart, causing a load on the heart, and over time, the person is prone to irritability, and the brain is prone to hypoxia and short circuit.

Wrinkles occur when people are angry, the brain nerve cells in the body will age faster, and anger will have an impact on our psychology.

..Of course it's harmful.

You know, people who are often angry can get old easily.

Especially when you are old, the wrinkles on your face are one by one, like small grooves, which can trap a fly alive.

Anger leads to endocrine disorders, and then the brain will command the body to synthesize more cortisol, and if this substance accumulates too much in the body, it will affect the normal function of immune cells, so that the resistance will be reduced, and then cause diseases.

This is caused by central nervous system modulation. When angry, the sympathetic nervous system is excited, adrenaline and norepinephrine increase, the heart beats faster, blood pressure rises, and blood vessels constrict; The central nervous system causes the muscles to contract, and the whole body is in a state of high stress. The body trembles due to the tense contraction of the muscles.

The cardiovascular and cerebrovascular constriction is very harmful to the body, and it is dangerous if it is an elderly person.

Emotional agitation, the secretion of adrenal hormones accelerates.

Have you ever found that people who are angry and trembling are so angry that they can't speak? In fact, this kind of person's mouth can't be made temporarily. Since you don't adjust the "alarm clock", why not adjust it to vibration if you want to express your opinion? (humorous answer).
