SEEU. AGAIN 3pcs HC-SR04 Ultrasonic Sensor, Distance Sensor with Ultrasonic Transmitter and Receiver Module Compatible with MEGA2560 Robot XBee ZigBee
HC-SR04 Ultrasonic Module Distance Sensor for MEGA2560 Robot XBee ZigBee HC- SR04 Module main technical parameters: Voltage: DC 5V The Static Current: less than 2mA Output Signal: Electric frequency signal, high level 5V, low level 0V Sensor Angle: less than 15 degrees Detection Distance: 2cm-450cm Trigger Input Pulse width: 10uS Precision: 3mm Connection: VCC/ trig(T)/ Echo(R)/ GND (VCC supply 5V, and GND is ground wire. TRIG is trigger control signal input, ECHO is echo signal output.) NOTE: 1.The module should be inserted in the circuit before been powered to avoid producing high level of misoperation; if produced, power it again. 2.The module is not suggested to connect directly to electric, if connected electric, the GND terminal should be connected the module first, otherwise, it will affect the normal work of the module. 3.When tested objects, the range of area is not less than 0.5 square meters and the plane requests as smooth as possible, otherwise ,it will affect the results of measuring. Package included: 3 x HC-SR04 ultrasonic measuring sensor module.
Product Features
- Test mode :Using IO trigger for high level signal.( Not less that 10us),The Module sends eight 40 kHz automatically and detect whether there is a pulse signal back.
- The detection zone: 0.78~196 in/ (2cm~500cm); High precision: up to 0.12 in/(0.3 cm) Effectual angle: less than 15.
- Power supply: 5V DC; Quiescent current: less than 2mA.
- Test distance = ((Duration of high level)*(Sonic :340m/s))/2.
- Package included: 3 x HC-SR04 Ultrasonic Module.
