The product comes with 10 pieces of the HC-SR04 Arduino Ultrasonic Module HY-SR05 Distance Sensor. The technical details of the module include: a working voltage of 5V(DC), a static current of less than 2mA, an output signal that is an electric frequency signal, high level 5V, and low level 0V. The sensor angle is not more than 15 degrees and the detection distance ranges from 2cm-450cm with a high precision of up to 0.3cm. The input trigger signal is a 10us TTL impulse and the echo signal is output TTL PWL signal. Payment is only accepted through Paypal. The package includes 10 pieces of the HC-SR04 Arduino Ultrasonic Module HY-SR05 Distance Sensor. The satisfaction guarantee includes a 5-star positive feedback after receiving payment. The return policy states that 45-day money-back guarantee will be issued upon receipt of the original product. Only defective products or the wrong item will be offered an exchange or store credit. Return products must also be in their original condition. To use this module, it is important to insert it into the circuit before powering it on in order to avoid producing a high level of misoperation. When a power supply of 5V is provided, the output will be 5V if there is an obstacle in range and 0V if there is none. The out pin of this module is used as a switching output when used as an anti-theft module, and without the feet when used as ranging modules. The module's working principle involves IO trigger and the automatic sending of eight 40khz square wave pulses. It will then automatically detect whether there is a returning pulse signal. If there is a signal returning, it will output a high level and the time of high level continuing is the time of that from the ultrasonic transmitting to receiving.
