Your cart is empty. Specification:
Use voltage: 3.3-5V
Quiescent current: less than 2mA
Level output: high 5V low 0V
Induction angle: less than 15 degrees
Detection range: 0.78~157.48 in/ (2cm~400cm)
High accuracy: up to 0.12 in/(0.3 cm)
Trigger Input Pulse width: 10uS
Dimensions: 45 x 20 x 12mm/1.77 x 0.78 x 0.47in
Work Matters:
1.Using IO trigger for at least 10us high level signal.
2.Module can send 8 pro 40 kz square wave automatically, and will test if there is any signal returned.
3.If there is signals returning, through outputting high level and the time of high level continuing is the time of that from the ultrasonic transmitting to receiving.Test distance = (high level time * sound velocity (340M/S) / 2
Measurement operation:
1.This module is not suitable for energized connection. If you want to connect with energization, please connect the Gnd terminal of the module first.
2.If the test surface is not very regular or when testing distant objects, multiple measurements can be used to correct it.
3.The interval between two tests should not be less than 200mS.
Display module:
Test result can be displayed through digital tube and serial port at the same time.
Digital Tube Display: plug in the ultrasonic module directly, connect to the 5V power supply.
Serial Port Output: plug in the ultrasonic module, the port VCC, TX, RX, GND are respectively connected to the 5V, RX, TX, GND of the USB to TTL module.The serial communication baud rate is 9600 and the output format is“D: XXX\R\N", where XXX represents distance. The display unit is cm.
Package Includes:
5 x HC-SR04 Ultrasonic Sensor module
5 x Mounting Bracket(with screws kit)
1 x Ultrasonic Sensor ranging display module
20 x Male to Female DuPont Cable
20 x Female to Female DuPont Cable
