Product Name: Blue Ultrasonic Measuring Sensor Module Hc-Sr04 Uno R3 Mega2560 for Arduino Model NO.: FUT3261 Customized: Customized Certification: CE Detection mode: Direct Reflection Type Sensitivity: High Output Signal Type: Digital Type Type: Open Ultrasonic Sensors Trademark: FUT Transport Package: Carton Specification: 10g Origin: China HS Code: 85340090 Product Description Operating Voltage 5VStatic currentLess than 2mASensor angleLess than 15 degreesDetection distance2cm-450cmHigh precisionUp to 3MMWeight10gModule 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.4. Sensor angle: Not more than 15 degrees.5. Detection distance: 2cm-450cm.6. High precision: Up to 0.3cm7. Input trigger signal: 10us TTL impulse8. Echo signal: Output TTL PWL signalMode of connection:1. VCC2. Trig(T)3. Echo(R)4. GNDSpecifications:This module performance and stability, accurate measurement of distance, SRF02 comparable ultrasonicRanging module. Module of high precision, blind area (2cm )super close, stable range is the success of thisProduct to market the strong basis!Main technical parameters:1: Voltage: DC5V2: Static current is less than 2mA3: Output: High4: Low level output: 5V0V5: Induction angle: Not more than 15 DEG6: Detecting distance: 2cm-450cm7: High precision: Up to 3mmConnection mode, VCC, trig (control side), echo (receiver ), GND wireThis product use: Acontrol orifice with a10US above high level, can be in the receiving port to wait for high level output.The output of the timer can be opened, when the orifice is low we can read the timer value, this time for the ranging time,We can calculate the distance. So continuous cycle test, can achieve your mobile measurement value ~~Module working principle:(1) using IO trigger location, to at least10us high level signal;(2) module to automatically send8 40kHz square wave, to automatically detect whether asignal return;(3) areturn signal, through the IO outputs ahigh level, high level for atime isUltrasonic wave from the transmitter to the return time. Testing distance =( high level time *speed of sound (340M/S )) /2;Competitive Advantage:1. Convenient &Friendly Customer Service2. Low Prices Direct From Factory Suppliers3. Fast Delivery Around the World.4. High Quality With Global Standards.5.1 Year Factory Warranty6. Safe Shipping Way and Payment
