Product Name: Blue Ultrasonic Sensor Module Hc-Sr04 Model NO.: HC-SR04 Customized: Customized Detection mode: Direct Reflection Type Measuring Medium: Gas Probe Type: Dual Probe Sensitivity: High Output Signal Type: Digital Type Type: Open Ultrasonic Sensors PCB Board Color: Red Trademark: DAGU Transport Package: Simple Package Origin: China HS Code: 90230090 Product Description Blue Ultrasonic Sensor Module HC-SR041. Detection distance: 2cm - 450cm, super close blind spots ( 2cm )2. Provides a full set of ranging process3. Measuring precision up to 3mm4. Adopt IO trigger through supplying at least 10us sequence of high level signal5. The module automatically send eight 40KHz square wave and automatically detect whether receive the returning pulse signal6. If signals returning, through outputting high level and the time of high level continuing is the time that from the ultrasonic transmitting to receive7. Static current: less than 2mA8. Working voltage : DC 5V9. Output signal: electric frequency signal, high level 5V, low level 0V10. Sensor angle: not more than 15 degrees11. Mode of connection: VCC / trig ( T ) / echo ( R ) / GND
