We are in a technologically intelligent era, where everything is changing and changing with each passing day. Smart home appliances are constantly upgraded on the original basis, which facilitates our lives and brings us unlimited surprises. Among them, the Smart Home temperature sensor is an example. This Smart Home temperature sensor can monitor the room temperature at any time and provide people with a comfortable temperature.
What are the functions of Smart Home temperature sensors?
How does the Smart Home temperature sensor work in the kitchen?
How does the Smart Home temperature sensor ensure safe operation?
The test function of the new Smart Home temperature sensor is also continuously enhanced. For example, the DS1629 single-wire temperature sensor adds a real-time calendar clock (RTC) to make its functions more complete. DS1624 has also increased the storage function, using the 256-byte E2PROM memory inside the chip, which can store the user's short messages. In addition, Smart Home temperature sensors are developing from single-channel to multi-channel, which creates good conditions for the research and development of multi-channel temperature measurement and control systems.
In the process of cooking in the kitchen, when people are cooking, they need to mix different condiments in different periods and at different temperatures, and then perform different degrees of stir-frying, and in the process of frying The temperature of the pot is strictly controlled to prevent the food from being spoiled. Therefore, the use of intelligent temperature sensors for temperature detection has a critical impact on the quality of food for measuring the accuracy of the temperature of the pot and alarming when necessary.
The safety and reliability of smart temperature sensors are very important. Traditional A/D converters mostly use integral or successive comparison conversion techniques, which have low noise tolerance and poor ability to suppress aliasing noise and quantization noise. Smart Home temperature sensor generally uses a high-performance Σ-Δ A/D converter, which can convert analog signals into digital signals at a high sampling rate and low sampling resolution, and then use oversampling, Noise shaping, and digital filtering technology to improve effective resolution.
The Σ-Δ A/D converter can not only filter quantization noise but also has low requirements on the accuracy of peripheral components. To avoid misoperation when the temperature control system is disturbed by noise, a programmable "fault queue" counter is set up inside the intelligent temperature sensor, which is dedicated to allowing the measured temperature value to exceed the upper and lower limits Several times. The interrupt terminal can only be triggered when the number of times the measured temperature continuously exceeds the upper limit or lower than the lower limit reaches or exceeds the set number n (n=1~4).
With the advancement of technology, the Smart Home temperature sensor has expanded with many new functions and features, to a large extent meet people's current needs, and continuously improve the quality of people's life and the happiness of the living environment.
