The STM32L4 has the capability of counting people with the ToF sensor?

[Uwe Bonnes]

There is not ToF sensor in any STM32. You can connect a ToF sensor and then write a program for your needs.

i'm talking about the B-L475E-IOT01A Discovery Kit for Iot

Would have been helpful if you had said that, instead of just "STM32L4" - then people would know what you're talking about:

https://www.st.com/en/evaluation-tools/b-l475e-iot01a.html

There's a description of the ToF sensor in the User Manual:

https://www.st.com/resource/en/user_manual/dm00347848-discovery-kit-for-iot-node-multichannel-communication-with-stm32l4-stmicroelectronics.pdf

See section 7.2.6

With a range of "up to 2m", it sounds like it should be feasible to do some sort of people counting.

Take a look at the supporting Tools & Software:

Probably also take a look at the resources on the ToF Sensor's Product Page:

You're right, that was my bad to begin with.

Thank you for that answer, it helped a lot.

The idea is to replicate what ST did on that "People Counting Using a Single ST VL53L1X Time-of-Flight Sensor" demo.

Do you think it is possible to use the same algorithm on the L0x?

[Andrew Neil]

Have you tried searching to see if you can find the code for that demo ?

EDIT

Hi ,

People couting demo is developed by single VL53L1X because of its multi field of view/multi zone capabilites which is not supported by VL53L0X. So VL53L0X is not a suitable candidate for people counting. Secondly all our SW are released based on STM32F4 and STM32L4 series.So you can choose any one of MCU and evaluate the feature. Hope it helps.
