1.1 Model design (1) Parameter calculation: The central operating frequency fc of the system is 915 MHz, and the calculation formula of the central working wavelength c is: The characteristics of the helical antenna are determined by D . In....
In many power equipments, due to the installation process and aging, etc., the contact resistance of the power line contacts becomes large, which in turn causes the temperature to rise, and in severe cases, the contacts are blown, causing po....
Figure 1 Measurement interface circuit Figure 1 shows the interface circuit of the thermistor sensor using the in-phase amplifier circuit for temperature measurement. The interface circuit uses a resistor to linearize the thermistor sensor,....
Unlike thermistors, TI analog temperature sensors measure very well over a wide temperature range and have a linear output over the entire operating range. You dont have to worry about the inventory of different devices. In addition, TIs uni....
DS18B20 is a commonly used digital temperature sensor with small size, low hardware overhead, strong anti-interference ability and high precision. The DS18B20 digital temperature sensor is easy to connect and can be used in a variety of appl....
DS18B20 performance 1, the unique single-wire interface mode, the DS18B20 only needs one port line when connecting with the microprocessor to realize the two-way communication between the microprocessor and the DS18B20. 2, temperature range....
The read and write timing and temperature measurement principle of the DS18B20 is the same as that of the DS1820, except that the number of bits of the obtained temperature value varies with resolution, and the delay time during temperature....
Multi-sensor high accuracy digital temperature measurement system LTC2983, which can measure a variety of temperature sensors and digitally output the results (in oC or oF) with 0.1oC accuracy and 0.001oC resolution. Today we are talking ab....
A thermocouple is a temperature sensing element and is a meter. It directly measures the temperature and converts the temperature signal into a thermoelectromotive force signal, which is converted into the temperature of the measured medium....
The linear temperature sensor is a linearized output negative temperature coefficient (ntc) thermal element. It is actually a linear temperature-voltage conversion component, that is to say, under the condition of operating current (100ua),....
