ULTRASONIC MODULE HC SR04 IN INDIA

Ultrasonic ranging module HC - SR04 provides 2cm - 300cm, non-contact measurement function, and the ranging accuracy can reach to 3mm. The modules includes ultrasonic transmitters, receiver and control circuit. The performance of this module is stable and precise measure of distance.   And comparable foreign SRF05, SRF02 Ultrasonic Ranging Module.   Module precision, blind spots (2cm) super close, stable distance measurement. This module resembles GH-311. Main technical parameters: 1.     Voltage: DC5V 2.     Quiescent Current: 3.     level output: the output of the high-5V 4.     detection range: 2cm-300cm 5.     Dimension mm 6.     Trigger Input Signal 10uS TTL pulse The module works: (1) IO trigger ranging to at least 10us high signal; (2) module automatically sends eight 40kHz square wave, automatically detect whether a signal return; (3) the signal to return, a high IO output, high duration of Ultrasonic time from launch to return.   Test distance = (time high * speed of sound (340M / S)) / 2   Package Contain: 1xUltrasonic Module
