[color=rgb(68,68,68)][backcolor=rgb(255,255,255)] The ADXL362 consumes 2 μA (100 Hz) in full measurement mode and only 300 nA in motion detection wake-up mode. In addition to native low power operatio...
Due to cost constraints, the cost of CCD chips needs to be controlled within 100 yuan. We haven't found a suitable one yet (needs to be above 60fps). Now I have a stupid idea, but I don't know if it c...
As the title suggests, I plan to use MSP430 (other boards such as STM32 and FPGA are also OK) to collect data and transmit it to the Internet through the network for real-time detection. This is the g...
