ITEM NAME:2X HC-SR04P Ultrasonic Ranging Module Range Sensor Module 3-5.5V Wide V PQN Descriptio n Description: Material: FR4 Color: picture color Size: 6 * 3 * 2.5 cm Main technical parameters: 1.Working voltage :5V(dc) 2.Static current: less than 2mA. 3.Output signal: electric frequency signal, high level 5V, low level 0V. What's my job?Sensor Angle: no more than 15 degrees. 5.Detection distance: 2cm-450cm. 6.High accuracy: up to 0.3cm 7.Input trigger signal :10us TTL pulse 8.Echo signal: output TTL PWL signal Connection: 1. The VCC 2. The triangle (T) 3. The echo (R) 4. The ground Usage: The power module is 5V. When the obstacle is in range, the output is 5V; otherwise, the output is 0V.The output pin of the module is used for the switch output of the anti-theft module, and there is no need for the pin when ranging the module. Note: the module should be inserted into the circuit before power on to avoid high level misoperation;If not, power it again. Working principle of the module: 1. IO trigger is adopted by providing at least 10us high level signal sequence. 2. The module automatically sends 8 40khz square waves and automatically detects whether the returned pulse signal is received. 3. If there is a signal return, the high level will be output, and the duration of the high level is the time from ultrasonic transmission to reception.Test distance =(high level time * sound velocity (340 m/s)/ 2. Note: this module is not suitable for electric connection. If it is necessary to connect this module with electronic power supply, the GND terminal of this module should be connected first, otherwise the normal operation of the module will be affected Product list :2pcs* ultrasonic ranging module We offer you what you need! 2X HC-SR04P Ultrasonic Ranging Module Range Sensor Module 3-5.5V Wide Voltage.IO trigger is adopted by providing at least 10us high level signal sequence.
