Ultrasonic Module HC-SR04 Distance Measuring Transducer Sensor

Ultrasonic ranging module HC-SR04 provides 2cm - 400cm non-contact measurement function, the ranging accuracy can reach to 3mm. The modules includes ultrasonic transmitters, receiver and control circuit.  


Specifications:

Module Main Technical Parameters:
Power Supply: 5V DC
Quiescent Current: 2mA
Effectual Angle: 15 degree
Ranging Distance: 2cm - 450cm
Resolution: 0.3cm
Output Signal: Electric frequency signal, high level 5V, low level 0V.
Input Trigger Signal: 10us TTL impulse
Echo Signal: Output TTL PWL signal Mode of Connection:
1. VCC
2. trig (T)
3. echo (R)
4. GND Use Method:
- Supply module with 5V, the output will be 5V while obstacle in range, or 0V if not. The out pin of this module is used as a switching output when anti-theft module, and without the feet when ranging modules. Note: The module should be inserted in the circuit before been power, which avoid producing high level of misoperation; if not, then power again. Module Working Principle:
- Adopt IO trigger through supplying at least 10us sequence of high level signal.
- The module automatically send eight 40khz square wave and automatically detect whether receive the returning pulse signal.
- 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 x sound velocity (340M/S) / 2. Note: This module is not suitable to connect with electric power, if you need to connect this module with electronic power, then let the GND terminal of this module to be connected first, otherwise, it will affect the normal work of the module.

Great Service, Great ProductMy son is a keen rugby player and we have looked for a good supplier of rugby equipment for a while. Came across the Barrington Sports 'web page' by chance and was very impressed by the extensive range of products & brands. My son wanted a new kit bag to carry his rugby kit in and being a 'fussy fashion conscious' 17 year old, he was looking for style & practicality. He decided on a Kooga bag. To set-up an account and order the product was easy. The item arrived within a couple of days and my son was extremely happy with the product. An excellent service and a pleasure to deal with, we will definitely be purchasing goods from Barrington Sports in the future.
