MB1043 Ranging sensor is the most cost-effective low-cost high-quality solution in applications..The module has accurate ranging,Low pressure operation,Ultra-small volume.The sensor can provide high precision and high resolution ultrasonic proximity detection.,Can Detect1Cubic inch size object,The sensor has1Millimeter resolution,Working voltage compensation is carried out inside the module.,Improve Accuracy,Suppress external noise sources,Internal speed acoustic temperature optimization compensation,External temperature compensation can also be connected.The sensor can detect1mmTo5Objects within meters,Blind area is3０cm,In1－30cmInside,Always displayed30cm,In30-500cmHas greater sensitivity.
Multiple output modes:
3,Serial number orRS232OrTTLEqual output format.
Pin1:TempTemperature Sensor connecting foot:Disconnect this foot without temperature sensor,In order to obtain the best accuracy,This pin is optional To HR-MaxTempTemperature sensor.QueryHR-MaxTemp (MB7955, MB7956, MB7957,Additional information of temperature sensor.
Pin2: PWPulse width output:This pin outputs the pulse width representing the distance.,The proportional coefficient is per millimeter1uS .The output range is300uSFor300Millimeter5000uSFor5000Millimeter,Pulse width output has lower precision than serial output.0.5%.
Pin3: ANAnalog voltage output:When starting up,The voltage on this pin is set0V,After the work is turned on,The voltage on this pin corresponds to the voltage of the nearest measured distance..Analog voltage and distance and scale factor(Vcc/5120)Every1Millimeter.The formula is:S=ADJ*(Vcc/5120)The distance obtained ismmUnit range.
Distance output is5Millimeter resolution.(This output voltage referenceGND)Analog voltage output is usually output in serial±10Within millimeters.
Example:Use one10BitAD,You can read the analog voltage bit directly.(IE0To1024),Just putADNumber of reads multiplied5,To generatemmRange in units.For example,60Bits correspond300-mm(Among them60 * 5 =),Among them1000Bit correspondence5000-mm(Among them1000 * 5 = 5000-mm).5VRatio of power supply~0.977 mV / 1Millimeter.Voltage5VWhen supplying power,300Millimeters are293mV, 5000Millimeters are4.885V.
Pin4: RXControl foot:Ranging begins/Stop:The inside of the initial pin has been pulled up.If this pin is not connected or set high,The sensor will be100MSPeriodic continuous measurement and output range data.If you keep it low,The sensor will stop ranging.Or provide20uSThe above high level pulse triggers the sensor to work.,The cycle of such workYou can set it at will..
Real-Time range data: When pin4When it is low first and then high,The sensor will work in real time and make a reading.,The output will be the range measured by the First Command range reading..When the sensor tracks4Read distance each time the pin is low,Then4Pin up,Get unfiltered real-time distance information for speed is every100Ms.
Filter distance data:When pin4When keeping high,The sensor will continue every100mSMake a distance measurement,But the output will pass2HzFilter,The sensor will output the distance according to the final distance information..(This data is the most*Quasi)
Pin5: TXSerial Output:By default,Serial output isRS232Format(0ToVcc), Resolution is1Millimeter.If you wantTTLOutput,WillPCBThe jumper on the back can be short-circuited.,As shown on the right.For bulk orders,TTLOptions can be welded free of charge before leaving the factory..Serial output is the mostQuasiRange output.The serial data sent is 9600Porter,8Bit Data,No parity,1Bit stop.
Pin6: VCCPositive pole of power supply,The working voltage of the sensor is2.5-5.5V.
Pin7: GNDNegative pole of power supply.
