HC-SR04P HC-SR04 Ultrasonic Ranging Module Range Sensor Module 3-5.5V Wide Voltage Performance Product parameters: Using voltage: DC5V Quiescent current: less than 2mA Level output: high 5V Level output: bottom 0V Sensing angle: no more than 15 degrees Detection distance: 2cm-450cm High precision: up to 0.3cm

Module working principle: (1) Use IO to trigger ranging and give a high-level signal of at least 10us; (2) The module automatically sends 8 40khz square waves and automatically detects whether there is a signal return; (3) If there is a signal return, a high level is output through IO. The duration of the high level is the time from the ultrasonic wave from emission to return. Test distance = (high level time * sound speed (340M/S))/2;
