ntDescription:
nt
ntWorking Voltage : 5V(DC)
ntStatic Current: Less than 2mA.
ntOutput Signal: Electric frequency signal, high level 5V, low level 0V.
ntSensor Angle: Not more than 15 degrees.
ntDetection Distance: 2cm-450cm.
ntHigh Precision: Up to 0.3cm
ntInput Trigger Signal: 10us TTL impulse
Signal : output TTL PWL signal
ntMode of connection:
ntVCC
nttrig(T)
ntech0(R)
ntGND
nt
ntUse Method:
nt
ntSupply module with 5V, the output will be 5V while obstacle in range, or 0V if not.The out pin of this module is used as a switching output when anti-theft module, and without the feet when ranging modules.
ntNote : the module should be inserted in the circuit before been power, which avoid producing high level of misoperation;if not, then power again.
nt
ntModule Working Principle:
nt
nt1. Adopt IO trigger through supplying at least 10us of high level signal.
nt2. The module automatically send eight 40khz square wave and automatically detect whether receive the returning pulse signal.
nt3. If there is signals returning, through outputting high level and the time of high level continuing is the time of that from the ultrasonic transmitting to receiving. Test distance =(high level time * sound (340M/S) / 2.
nt
ntNote:
nt
ntThis module is not suitable to connect with electric power, if you need to connect this module with electronic power,then let the GND terminal of this module to be connected first,otherwise, it will affect the normal work of the module
