Description: Operating voltage: 5V (DC) -
Static Current: Less than 2 mA. -
Output signal: Electric frequency signal, high level 5V, low level 0V. -
Angle sensor: not more than 15 degrees. - D
detection istance: 2cm-450cm.-
High accuracy: up 0.3cm-
Enter the trigger signal: TTL pulse 10us-
Echo signal: output signal mode -
TTL PWL disconnection: VCC trig (T) echo (R) GND -
Use the method: the power supply 5V, the output will be 5V while obstacle in range, or 0V otherwise. The axis of this module is used as a switching output when anti-theft module and without the feet when ranging modules.
Note: The module must be inserted in the circuit before been power, which prevents the production of high malfunction, if not, then on. Module Working Principle: Adopt IO trigger through supplying at least 10us sequence of high level signal. The module automatically sends eight 40khz square wave and detecting whether the receiving pulse signal back automatically. If there are signals back through the high-level output and the high level continuous time is the time that the ultrasound transmission to reception. Test distance = (high level time * sound velocity (340M / S) / 2.
Note: This module is not suitable to con
