    5Pcs HC-SR04 Ultrasonic Sensor Module Kit Distance Sensor Compatible with Mega R3 Duemilanove Nano for Robot XBee ZigBee by ElecRight

    • The IO port TRIG is used to trigger the distance measurement, giving a high level signal of at least 10us. The module automatically sends eight 40khz square waves, automatically detects whether there is a signal return; there is a signal return, through the IO port ECHO output a high level, while opening the timer timing, when this port becomes low, you can read the value of the timer, the duration of the high level is the ultrasonic time from the launch to the return of the time. Test distance = (high level time * speed of sound (340M/S))/2; us/58 = centimetres or us/148 = inches; (us for the echo high level signal duration) It is recommended that the measurement period of 60ms or more to prevent the impact of the emission signal on the echo signal. Product Parameters: Electrical parameters: HC-SR04 ultrasonic module Working voltage: DC 5 V Working current: 15mA Working frequency: 40kHz The farthest range: 4m Nearest range: 2cm Measuring angle: 15 degrees Input trigger signal: 10uS TTL pulse Output echo signal: output TTL level signal, proportional to the range Size: 45*20*15mm Precautions: 1, this module should not be connected with electricity, if you want to connect with electricity, let the GND end of the module connected first, otherwise it will affect the normal work of the module. 2When measuring the distance, the area of the object to be measured should be not less than 0.5 square metres and the plane should be as flat as possible, otherwise it will affect the resul
