I am looking for an (ultra lo power) Micro (and sensors) for a new product that has the following. Please suggest a Micro and sensors. The total price target should be under $7.
Hello Chandran,
Yes, we have sensors and MCU's below $7 for your use case. MMA8652FC will be a good sensor to consider for gesture recognitions such as shake, motion, orientation, etc and is priced about $0.54 for quantities of 1K . I'm not sure how much memory you would need for a 10 sec low res video on an MCU but we have K64_120 MCU that you can consider with 256 KB RAM and 1024 KB flash for $5.45 (10K quanitity pricing). So, totally sensor + MCU is within your budget of $7. Also you can try our eval boards FRDM-K64F (to evaluate the K64_120 MCU) and FRDM-FXS-MULT2B (to evaluate sensor MMA8652FC) . The MCU chip includes many GPIO pins that could be used for your LED's and relays.

Krithi,
Thanks for the info. By motion detector, I meant an infrared motion detector such that it detects a human nearby and wakes up the Micro, which starts the camera.
Best regards,
Chandran
