Ultrasonic SR04 + SG90 Servo + Bracket HC-SR04 Distance Sensor Module SG90 Micro Servo for RC 250 450 Helicopter

Ultrasonic SR04 + SG90 Servo + Bracket HC-SR04 Distance Sensor Module SG90 Micro Servo for RC 250 450 Helicopter

SR-04 Sensor Module

Description: This module performance is stable, measure the distance accurately. performance nearly the same as SRF05, SRF02 SRF05, SRF02 ultrasonic distance measuring module and other comparable. Module High precision, blind spots (2cm) super close. Parameter: Voltage: DC 5V Static current: le than 2mA Electrical level output: 5V high Electrical level output: at the end of 0V Induction angle: not more than 15 degrees Detection distance: 2cm-450cm High precision: 2mm Wiring: VCC, trig (control side), echo (receiving end), GND Module work: Using IO trigger distance, the high signal to at least 10us module automatically sends eight 40khz square wave, automatically detects whether a signal return, a signal back, through the IO output a high electrical level, high electrical level duration is: the ultrasound time from launch to return. Test distance = (time of the high electrical level * speed of sound (340M / S)) / 2
