3. How It Works (Operational Theory)

The sensor uses a single transducer to both emit and receive sound waves.

1. Trigger: The microcontroller sends a 5V pulse to the SIG pin lasting at least 2 microseconds (usually a 5 µs pulse is recommended) to initiate a reading.
2. The Burst: The sensor emits a 40 kHz ultrasonic chirp (consisting of 8 cycles).
3. Echo: Immediately after the burst, the sensor sets the SIG pin HIGH.
4. Measurement: The SIG pin stays HIGH until the ultrasonic echo is detected returning to the sensor.
5. Calculation: The duration the SIG pin stays HIGH corresponds to the time it took for the sound to travel to the object and back.

Based on the part number PAN186CV, you are likely referring to the Parallax #29088 PING))) Ultrasonic Distance Sensor.

Note: "PAN186CV" is a very common misreading or typo of the part number printed on the bottom of the Parallax PING))) sensor (often misread as PAN vs. P/N or similar silkscreen text). This guide covers the specifications and usage of the Parallax Ultrasonic Sensor (#29088), which is the standard device associated with that physical form factor and labeling style.

Section 8: Design Considerations for PAN186CV Integration

When using the PAN186CV datasheet as your design guide, pay attention to these practical aspects:

PCB Layout Guidelines:

• Keep the trace from B- to the source of the discharge FET as short and wide as possible.
• Place the 0.1µF capacitor directly between VDD and VSS (less than 5mm of trace).
• Do not route high-current paths near the VM or CO pins.
• Use Kelvin connections for current sense if possible.

Thermal Management:

• The PAN186CV itself dissipates very little power (<1mW typically), but the external MOSFETs may need a copper pour for heat sinking.
• Ensure the VM pin resistor (typically 1kΩ) can handle 0.1W – a 0603 or 0805 package is fine.

Compatibility:

• Verify that your battery’s internal resistance and your load’s peak current do not exceed the overcurrent threshold. For a 2A load, choose FETs with Rds(on) such that I*R < V_oc_detect (e.g., <0.1V).

5. Interfacing with Arduino

Because the PING))) uses a single pin for both input and output, the code must switch the pin mode dynamically.

Wiring:

• GND -> Arduino GND
• 5V -> Arduino 5V
• SIG -> Arduino Digital Pin 7

Code Example:

const int pingPin = 7;
void setup() 
  Serial.begin(9600);
void loop() 
  long duration, cm;
// 1. The PING))) is triggered by a HIGH pulse of 2 or more microseconds.
  // Give a short LOW pulse beforehand to ensure a clean HIGH pulse:
  pinMode(pingPin, OUTPUT);
  digitalWrite(pingPin, LOW);
  delayMicroseconds(2);
  digitalWrite(pingPin, HIGH);
  delayMicroseconds(5);
  digitalWrite(pingPin, LOW);
// 2. The same pin is used to read the signal from the PING))): a HIGH
  // pulse whose duration is the time (in microseconds) from the sending
  // of the ping to the reception of its echo off of an object.
  pinMode(pingPin, INPUT);
  duration = pulseIn(pingPin, HIGH);
// 3. Convert the time into a distance
  cm = microsecondsToCentimeters(duration);
Serial.print(cm);
  Serial.print("cm");
  Serial.println();
delay(100);
long microsecondsToCentimeters(long microseconds) 
  // The speed of sound is 340 m/s or 29 microseconds per centimeter.
  // The ping travels out and back, so to find the distance of the
  // object we take half of the distance travelled.
  return microseconds / 29 / 2;

Section 5: Typical Application Circuit (From the Datasheet)

Every PAN186CV datasheet includes a reference schematic. Here is the standard one:

Components list:

• R1 (VDD resistor): 330Ω to 1kΩ – limits current into VDD pin.
• R2 (VM resistor): 1kΩ – for overcurrent sense.
• C1 (VDD capacitor): 0.1µF – noise filtering.
• Q1 (Charge FET): N-channel MOSFET with low Rds(on) (<30mΩ).
• Q2 (Discharge FET): N-channel MOSFET (often dual MOSFET in one package).
• B+ / B-: Battery terminals.
• P+ / P-: Pack positive and negative output.

Circuit operation:

1. During normal operation, both CO and DO are high (>VDD-0.5V), turning on both FETs.
2. If overcharge is detected, CO goes low, turning off the charge FET.
3. If over-discharge or overcurrent is detected, DO goes low, turning off the discharge FET.

Common mistake: Swapping Q1 and Q2 positions will cause the protection to fail. The datasheet clearly shows the charge FET’s body diode must point toward the charger positive.
