LD1158E is based on one transmitter and one receiver chip multi-application millimeter wave sensor transmits 24G millimeter wave to detect the target, and after analysis, output the distance information of the moving target through the serial port. Through the serial port can be quickly integrated with serial tools or MCU to save configuration time. Accurate output of the target distance information, to solve the smart home kitchen and bathroom field sensor measurement range can not be normalized, effectively eliminate the measurement range outside the target caused by false alarms, false touch problem.
