Ultrasonic Sensor HC-SR04 Distance Measuring Module

199.00 150.00

Product Description:

 This HC-SR04 ultrasonic module can realize 2 ~ 700cm of non-contact ranging function,

has 5 V of wide voltage input range, static power consumption is less than 3mA. Their

 own temperature sensor will revise the ranging and has many communication modes like

GPIO, just like watchdog inside, very stable and compact.


Working Voltage: 5V(DC)

Static Current: Less than 2mA

Output Signal: Electric frequency signal, high level 5V, low level 0V

HCSR04 Ultrasonic Sensor


Sensor Angle: Not more than 15 degrees

Detection Distance: 2 cm to 450 cm

High Precision: Up to 2mm

Input Trigger Signal: 10us TTL impulse

Echo Signal: Output TTL PWL signal

Note: The module has a blind spot of 2cm (very near)

So obstacle held too closely will not be detected.

Estimated Delivery Date April 28, 2019
