1. Is there an advantage in power consumption?

Power consumption is one of our key areas. TI has a great advantage in low power consumption

2. Now that intelligent control is portable, power consumption control is critical. Would you like to know about TI's advantages in this regard?

TI has done a good job in low power consumption. We have some reference designs that can support a 10-year battery life

3. What bottlenecks are there in new sensor technologies?

New sensors are constantly developing in terms of low power consumption, high resolution, and connection methods

4. For smart homes, what are some good solutions for low power consumption and networking?

Due to the wide scope of smart home, we cannot cover it today due to time constraints. We will launch some special exchanges in the future.

5. How to solve the power frequency interference of the sensor?

If the output signal of the sensor is an ordinary analog signal, it is more susceptible to interference. TI's solutions have different solutions in terms of anti-interference.

6. Does TI have a wireless chip based on lora?

Based on wireless, we will have a special introduction. Due to time constraints, we cannot cover it today. We are very sorry.

7. What packages are there for sensors? How small can the volume be?

TI's products are mainly chips, so the volume of sensor chips is very small compared to traditional solutions. The size is mainly determined by the chip package.

8. Contactless?

Proximity sensing, so it is contactless

9. How about the penetration ability of inductive touch?

Inductive touch can be used as metal buttons

10. What are the advantages of inductive non-contact compared with capacitive?

Capacitive type has higher requirements on panel material, inductive type can be used in places where capacitor cannot, for example, all-metal panel, metal touch button

11. What is the most feared thing about touch is long-term wear and tear, will the life span be short?

Compared with mechanical buttons, the life span of touch buttons is very long. No matter how long it takes, human fingers cannot wear out the glass

12. What modes of use does inductive touch support? Can you provide technical support for later development?

TIThere are corresponding development kits and WEBENCH. It is very simple and easy to use.

13. Will the metal panel be triggered by mistake after being disassembled and assembled once?

It requires the cooperation of some structural parts.

14. What is the thickness of the metal layer and how to ensure the deformation requirements?

The thickness of the metal layer depends on the user's feel. When it is thicker, the user needs a greater pressing force

15. Can inductive type only be used for metal buttons?

It is not limited to metal buttons. Metal buttons are just one of the typical applications

16. Do you have a design schematic designed into the Internet of Things?

Sorry, due to time constraints today, I will communicate with you about the Internet of Things next time. You can download information about IoT from the TI official website, including schematics, etc.

17. HDC1000 is not recommended for new designs on the TI website. Is there an updated replacement product?

Yes, I will introduce Roadmamp to you right away

18. Where is gesture recognition currently used in the market?

Gesture recognition is now widely used, such as air conditioners, TVs, refrigerators, etc.

19. Many humidity sensors are inaccurate at the low end and have large errors

TI's temperature and humidity sensors have very high accuracy

20. Does TOF emit visible light?

In general, invisible light is used, and the user experience of visible light is not good

21. What is the typical resolution of a 3D TOF sensor?

The distance is about 30m. The resolution mainly depends on the pixels of the sensor. The distance resolution is about 0.5-1cm

22. Will the 3D TOF sensor be affected when used in sunlight?

Yes, but the impact is not that great. It is much better than binocular measurement. The frequency of TOF is low frequency and is not directly related to the spectrum, but light affects the amplitude detection of the receiving end

23. What is the subsequent development support for OPT8241?

Because of TOF, TI is currently on the sensor side, and it is difficult for TI to directly support user design. However, TI has close cooperation with third-party support. You can contact our agents.

24. Compared with similar capacitive sensors, what are our advantages?

Anti-interference, detection distance and response speed

25. Does the product window need to be configured with a filter?

The front end is similar to the camera

26. Is this sensor compatible with IIC and SPI three-wire?

Generally not, only one of them

27. Can the accuracy reach 30cm?

It depends on the size of the capacitive electrode sensor. Currently, the distance is close to 50CM.

28. Do you have any cool capacitive sensing applications? Please share them.

Automatic water filling of coffee machine

29. I want to achieve plus or minus 0.1 degrees. Is there any way?

It is quite difficult at present. It may still require high-precision NTC with ADC. At the same time, the measurement range will not be too wide

30. Can liquid level detection be used in liquid level monitoring of medical sample addition? How much sample should be added?

Yes, the range can be very wide, mainly depending on the design of your electrode. FDC can measure 250nF capacitance, and the resolution can be 1pF

31. What are some of the world's famous sensor companies?

For example, Honeywell, etc.

1 degree, is there any way?
