  URM06‐ANALOG Ultrasonic SKU:SEN0152 Introduction Ultrasonic sensors emit ultrasonic pulses, and by measuring the time of ultrasonic pulse reaches the object and back to the transducer, the distance of sensor from the target object is calculated. They are widely used in detecting displacement, thickness, distance, water level, material level and transparent objects. The URM06 - Analog Ultrasonic sensor provides very short to long-range detection and ranging from 20cm ~ 10m, comes in a compact, robust PVC housing and matches 35mm electrical pipe mounting. It comes with analog interface and works at high output acoustic power. The ultrasonic sensor detects objects from 20cm to 1000cm and provides range information with 1cm resolution. The URM06 has 15 degree beam angle which has excellent receive sensitivity. And it works best when detecting soft targets. The similar sensors are widely used in professional mobile robot systems such as Pioneer robots. The URM06 series sensors are the best ultrasonic sensor available in the market regarding its beam angle, senstivity and accuracy. Specification                Working Voltage: 6V-12V (5V is acceptable but not recommended) Rated Current: 16mA Peek Current: 2A Interface: Analog Working Frequency: 49.5KHZ Working Temperature: -10 ~ ＋70 Detecting Angle: 15°（-6dB） Detecting Range: 20cm ~ 10m Size: 50mm(diameter)*43mm(length) Mounting Thread Diameter: 35mm Weight: 45g Applications      robot navigation obstacle avoidance measuring distance devices engineering measurement tools industrial control system Connection Diagram Connection Diagram Pin Definition     VCC: 6~12V@Max 2A (5V is acceptable but not recommended) GND: Ground Trig: Measurement trigger pin - Low level pulse over 50us triggers one distance measurement. Holding this pin LOW will repeats the measurement every 100ms. OUT: Analog output pin – 0.33mV stands for 1mm. Sample Code   #include "Arduino.h" /* Trig: Measurement trigger pin - Low level pulse over 50us triggers one dista nce measurement.
