aj sr04m datasheet

1. Overview & Key Differentiators The AJ-SR04M is an improved, industrial-grade variant of the popular HC-SR04. Unlike the standard HC-SR04, this module is enclosed in a waterproof, IP67-rated housing , making it suitable for outdoor, dusty, or humid environments (e.g., tank level sensing, outdoor robotics, car reverse sensors).

def get_distance(): GPIO.output(TRIG, False) time.sleep(0.05) GPIO.output(TRIG, True) time.sleep(0.00001) GPIO.output(TRIG, False)

void loop() digitalWrite(TRIG, LOW); delayMicroseconds(2); digitalWrite(TRIG, HIGH); delayMicroseconds(10); digitalWrite(TRIG, LOW);
