US-100 Ultrasonic Sensor Distance Measuring Module with Temperature Compensation

The US-100 Ultrasonic Sensor measures distance by emitting ultrasonic waves and measuring the time it takes for the echo to return. It features temperature compensation to ensure accuracy across varying environmental conditions.

• Avoid Extreme Temperatures: Do not operate the sensor outside the temperature range of 20°C to 70°C to prevent damage or inaccurate readings.,
• Prevent Electrical Misconnection: Do not connect the Trig/TX or Echo/RX pins incorrectly to avoid damaging the sensor.,
• Avoid Obstructing Sensor Face: Ensure the sensor's path is clear of any obstacles within the sensing range to avoid erroneous measurements.

• Use Correct Voltage: Connect the VCC and GND pins to a power supply within the 2.4V to 5V range.,
• Select Correct Mode: Ensure the jumper is correctly placed for selecting between serial data mode and pulse width mode.,
• Use Correct Baud Rate: Set the microcontroller’s serial port to use 9600 baud at 8-N-1 when using in serial data mode.

• Description: The sensor has a sensing angle of 15°.

• Description: The maximum sensing distance is 450 cm.

• Description: The sensor operates within a voltage range of 2.4V to 5V.

• Description: Remove the shunt from the jumper to select pulse width mode. Connect Trig/TX to a digital output and Echo/RX to a digital input on your microcontroller.

• Description: Place the shunt on the jumper to select serial data mode. Connect Trig/TX to microcontroller’s TX and Echo/RX to RX. Set baud rate to 9600 at 8-N-1.
