Program introduction:
1. Electronic thermometer program introduction:
The electronic thermometer consists of a temperature sensor, a liquid crystal display, a button battery, an ASIC and other electronic components. It can quickly and accurately measure body temperature. Compared with traditional mercury glass thermometers, it has the advantages of convenient reading, short measurement time, high measurement accuracy, memory and buzzer prompts, especially the electronic thermometer does not contain mercury, which is harmful to human body and body. The surrounding environment is harmless, and it is especially suitable for use in family and other occasions.
2. The working principle of the electronic thermometer scheme:
The working principle of the electronic thermometer uses the temperature sensor to output electrical signals, directly output digital signals or convert current signals (analog signals) into digital signals that can be recognized by internal integrated circuits, and then pass them through displays (such as liquid crystals, digital tubes, LEDs, etc.) Matrix, etc.) display the temperature in digital form, and can record and read the highest value of the measured temperature. It is generally composed of a temperature sensing head, a temperature measuring rod, a display screen and a switch.
Three, electronic thermometer program function:
Brief description of the electronic thermometer solution:
