TIDA-010021: similar sensor design as TIDA-010021

Hi Jiejun,

Can you tell me what's your application?

For TIDA-010021, we cannot meet your requirements, but OPT3101 is just a AFE support 3 channels, you can choose different LED or even laser diode to meet your requirements, depends on the driver current OPT3101 can support.

In general., I don't think it can be done by OPT3101 for your requirement, but for your requirement, I would suggest using mmWave radar IWRL6843/IWR6432 on ti.com, are you aware of this? Do you have cost concerns?

Thanks

Joe

Sorry, IWR6843 and IWRL6432.

Hello Joe,

thank you very much for your quick feedback. very much appreciated. 

We would like to use the sensor for air conditioner products, in order to detect where the persons are and adapt the working mode e.g. wind level, speed, etc. of air conditioners accordingly. 

Besides, we are using already mmWave radar in the products since several years, but not 60GHz (I think we are using 25GHz in products now), because it is still not allowed by regulation yet. We prefer the design of TIDA-010021, as it is simple, cost effective and can cover large FoV as well. Do you think, it is possible to adjust some parameters of TIDA-010021 in software to fulfill some of the requirements? Or perhaps could we use other components to fulfill some of the requirements?

Many thanks again and have a nice day. :)   

best regards,

Jiejun

Hi Jiejun,

These requirement can be easily done by TI mmWave radar. But you mentioned the regulation, where are you from, China? As I know, only China has such regulations for 60GHz.

Any issue for using 25GHz radar? 

If you want to do some change on TIDA-010021, i would suggest change the emit Leds not the software, the Led decide the detecting range and FOV, you can choose different leds to meet your requirement, but it not easy to use OPT3101 for your functions, especially for 3 people identification and 5 zone. Have you consider using multiple sensor technology to do this？

Thanks

Joe

Hi Joe,

thank you for the reply. Yes, our products are sold in China. Currently, there is no issue by using 25GHz radar, the products with 25GHz radar are already in market since several years. Therefore, the R&D team would like to discover some new solutions in the market. 

Yes, we are also open for using multiple sensor technology to replace 25GHz mmWave radar. Perhaps we could think about the potential solutions in two directions below:

1. by changing LED on TIDA-010021 to cover some of the requirements. --> It's clear that this direction will not cover all of the requirements, maybe it can cover FoV>=120°, measure distance below 6m, distance accuracy 100mm by using one sensor; by adding several sensors, the 5 zones and 3 persons can be distinguished. Do you think it is feasible?

2. using multiple sensor technology to replace the mmWave radar. Here I have no clue at the moment, please feel free to suggest. 

Thank you and have a nice day. 

best regards,

Jiejun

Hi Jiejun,

For your question, as you said, I think for FOV, distance and accuracy, could be done by OPT3101, but to be honest, if you change different emit leds, the calibration process is quite complex, are you aware of this? For 5 zones and 3 person distinguished, it's hard to be done if we don't use radar solution.

If you want to ask multiple sensor technology, I suggest motion sensing solutions, like PIR, optical, camera, etc. See attached solutions.

Where are you located?  we can set a short call if needed.

Joe

Hi Joe,

thank you for your input. I was previously not aware of the complex calibration process caused by changing emit leds.

For sure, we can set up a short call to exchange. I am located in Germany. Please feel free to let me know, when you are available and your email address. I will send you a Teams meeting invitation. You can write me direclty an email (jiejun.du@haier-europe.com), if it is better for you.

Thank you and have a nice day. 

best regards,

Jiejun
