## Questions & Answers

**Q: Does it have an example code for use with a raspberry pi zero w or with an esp32 ?**
A: If by "it" you mean does the device come with sample code?  The answer is "No".  But there is a huge volume of info on YouTube and on the internet.  Just google either SR 04 sensor or the part number of this one.

Hope that helped.

**Q: Is this an automatic or controlled version?**
A: If you're asking whether the device will transmit and receive at regular intervals the answer is no.  The device requires a 10us wide active LOW pulse (I send a 50us wide pulse just to be safe).  Then the device will return a pulse whose width is proportional to the distance measured.  There are a number of different C++ functions that will perform this for you: Pin() and newPin() are two that come to mind.  Google them for more info.

Hope that helped.

**Q: Can I use with esp8266? And which one pwm or uart?**
A: Short answer: Yes you can.  And you can use either version depending on what you're trying to do.  One version just runs continuously, while the other requires that (in your case) the ESP8266 output a 10us minimal active LOW trigger pulse.  That pulse tells the device to send an ultrasonic burst toward the target.  The device then switches to "Receive" mode and waits for an echo back from the target.  The pulse width of the echo pulse is proportional to the distance from the target.  There is an enormous volume of information on the subject on the internet.

Hope that helped.

**Q: Is there a sample code for use with Raspberry Pi Zero???**
A: Yes--assuming that you have an ANSI C compiler (and I imagine that you do) there is a huge volume of info on YouTube, as well as on various forums.  The only difference is that this device requires an active LOW trigger pulse of 10us minimum pulse width.

Hope that helped.

## Customer Reviews

### ⭐⭐⭐⭐⭐ How far is it?
*by S***E on July 30, 2023*

I bought this sensor to test the level of water in a tank. This type of sensor isn't as sensitive to the sides of the tank. So it doesn't pick up interference. I have been using it for over 6 months continualy and it is still working great.

### ⭐⭐⭐ Works but not as consistent as expected
*by G***Z on September 30, 2023*

I tried to use this sensor to track how much water is in a barrel. It worked more precise than the versions that only have the trigger and echo mode where you need to calculate the distance taking temperature into consideration, but after a week of operation outside (all sealed with silicone) suddenly it started giving erroneous readings (the container is 60cm deep, initially all readings were from 0-60 but now suddenly it jumps to 80cm and when I add water it jumps to 120cm...) can't really trust this readings and will replace with a pressure sensor with current loop.

### ⭐⭐⭐⭐⭐ Sensor Malfunction
*by D***D on January 25, 2023*

Ignore my comment below - Issue was new Arduino IDE 2.0 serial monitor does not default to auto scroll like previous versions-The product malfunctioned after use for about three months. Always reads 6.25 inches (15.90 CM) no matter what distance the object is from the sensor. I bought this product to sense the water level in my chicken coop waterer because it was waterproof. It is well constructed but did not last long. I am hesitant to purchase another one since the same issue may arise. Too bad because it was the exact sensor I wanted. When it worked it provided very accurate measurements. At $28 US dollars it should have lasted much longer. I guess I will have to use the standard $5 dollar sensor.
