5pcs Ultrasonic Module HC-SR04 MELIFE Distance Sensor with 3pcs Mounting Bracket 2 Wire Set for Mega R3 MEGA Mega2560 Duemilanove Nano Robot XBee ZigBee

  • Parameter -- New Version Power Supply: 3.3V -- 5V DC.
  • Operating Principle: Ultrasonic HC-SR04 distance measuring transducer sensor, it consists of ultrasonic transmitter, receiver, and control circuit..
  • HC-SR04 ultrasonic sensor module: Using IO trigger for at least 10us high level signal, when triggered it sends out a series of 40KHz ultrasonic pulses and receives echo from an object, the duration of the signal is the time from sending ultrasonic to returning..
  • Test Distance Formula: The distance between the unit and the object is calculated by measuring the traveling time of sound and output it as the width of a TTL pulse, HC-SR04 test distance following formula -- L = 1/2 x T x C (L is the distance, T is the time between the emission and reception, and C is the sonic speed)..
  • Package Include: 5 x New Version HC-SR04 Ultrasonic Sensors, 3 x Mounting Bracket with Screws, 10 x Female-Male Dupont Cables, 10 x Female-Female Dupont Cables..

Ranger RCI-2970N2 DX AM-FM-SSB-CW 10 & 12 Meter Mobile Radio

  • High power: The SR-655HPC uses four FQP13N10 MOSFET transistors that produce 70W PEP. This is not a CB (11 meter radio), it is a 10 meter radio.
  • Brilliant 7-Color LED backlit face plate (choose from 7 colors with the push of a button or let the CPU controller scan through all of the colors on its own).
  • Dimmer control (32-position), advanced clarifier, VFO, PC programmable, variable power control.
  • Digital Echo with dual front-mounted controls.
  • Up-Armored receiver: Stryker's exclusive receiver protection works even under the harshest conditions, such as those at a busy truck stop with many operators running high power radios. Receiver filtering is tighter than most radios on the market for superior adjacent channel rejection.
