Description
- weight: 485 g
Working Voltage : 5V(DC)
Static Current: Less than 2mA.
Output Signal: Electric frequency signal, high level 5V, low level 0V.
Sensor Angle: Not more than 15 degrees.
Detection Distance: 2cm-450cm.
High Precision: Up to 0.3cm
Input Trigger Signal: 10us TTL impulse
Signal : output TTL PWL signal
Mode of connection:
VCC
trig(T)

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:
1. Adopt IO trigger through supplying at least 10us of high level signal.
2. The module automatically send eight 40khz wave and automatically detect whether receive the returning pulse signal.
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 (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
Package Included:
1/3/5/10/20 x HC-SR04 Ultrasonic Module Distance Measuring Transducer (optional)

This module will be used for presence detection activating a ventilator when the room temperature is over 22C. This is made possible when you connect this sensor to a esp board and integrate this with Home Assistant where the automation is created and maintained. This module is of high quality and I would recommend it to everyone.

je ne peux pas encore commenté sur sa durée de vie. mais ce produit fonctionne très bien pour moi l'image sur le site parrait plus grande mais sa s'adapte bien a mon projet. 2 point a souligné ; a 400m 9 reponse sur 10 est bonne si votre système n'utilise pas de batterie relier le GND a la terre sinon ca va vaciller.

I purchased 10 of these for several projects I am working on. At first I was worried because they were very affordable, I didn't expect much. Once they arrived, I could see the quality was fantastic. They are also very accurate, well exceeding my expectations. For anyone interested, I created an Arduino library for it and put on GitHub - https://github.com/dan-power/Arduino-HC-SR04

Pros: Quite easy to figure out without any documentation, all the pins are either well-labeled or obvious. Good quality for the price.Also it is really small so it could be hidden if you wanted to. Cons: None that I can think of... Work right away and compatible with arduino, mbed and all kind of other mircocontroller boards. I don't have any cons till now and I can not think of any. Especially for this price!!! Other: Easy to interface to my Arduino, good deal. I will recommend this to friends.

Build quality is acceptable - works nicely - measurements are repeatable. Trig pin has pull-up resistor to 5V, and Echo pin is push-pull, so i recommend using level conversion when interfacing to e.g 3.3V FPGA (Sensor did not work well with 3.3 supply voltage) Price/Function ratio is good, almost excellent.
