HC-SR04 Work with Arduino Project
- HC-SR04 Compatible with Arduino Ultrasonic Sensor Can Send Eight 40 kHz and Detect Signal Back.
- When Signal Back, a High Level Signal Will be Outputed by IO, and the Duration of the Signal is the Time from Sending Ultrasonic to Returning
Ultrasonic Timing Diagram

Module Working Principle:
- Pull the Trig Pin to High Level for More Than 10us Impulse and the Module Start Ranging.
- The Module Sends Eight 40KHz Square Wave to Detect Whether a Signal is Returned Automatically.
- Finished Ranging, If Find an Object in the Front, Echo Pin will be High Level; Different Distance, Different Duration of High Level.
- So It is Easy to Calculate the Distance; The Distance = (Duration of High Level*Sonic: 340m/s) /2.

Pay Attention:
- 1. Before Powered,HC-SR04 Sensor Module Should be Inserted in the Circuit to Avoid Producing High Level of Misoperate; if Misoperated ,Power the Module Again.
- 2. HC-SR04 Ultrasonic Distance Sensor is NOT Suggested to Connect to Electric Directly, When Connected to Electric, the GND Terminal Should be Connected w/ Sensor Module, Otherwise,it will Affect the Module’s Normal Work.
- 3. When Tested Objects, the Area Range Should More than 0.5 Square Meters and the Plane Requests Smoothly; Otherwise,it will Affect the Results of Measuring.

- Reviewed in India on 6 April 2019Verified PurchaseI first bought this ultrasonic sensor for making an obstacle avoiding robot. And as I was noob with this whole robot game at that time, I almost did everything accidentally that could destroy the sensor.
I accidentally gave 9v as input 😂. And still, the sensor runs fine even today and I'm using it for my next project too. So, I rate it 5 out of 5. The only minor complaint was that the packaging was not so good. But never mind, they will get it safe and sound to you.
Great product You guys have my 👍 for this one.
- Reviewed in India on 17 August 2018Verified PurchaseIt is a good and compact product to go with Arduino. I bought it for building a kit to measure the water level in the overhead water tank. Though the product worked fine, it failed within a week. So far, I have changed two sensors and I am sure that this is not suitable for this application.
- Reviewed in India on 26 August 2024Verified PurchaseIt does what is supposed to do. I am satisfied.
- Reviewed in India on 23 June 2020Verified PurchaseThe product is very good. It is good for beginners. It measures large distances accurately but when it becomes less than 10cm to 15cm it gives quite inaccurate or unexpected result. But it is a preferable product.
- Reviewed in India on 14 June 2017Verified PurchaseIt works fine. If you want to use it just for testing for small purposes, then go ahead and buy. But if you want to use it in real life big projects, then you should go for a higher accurate & with much more precision sensors.
- Reviewed in India on 7 July 2016Verified PurchaseWorking great as expected. Measurements are accurate..I am using it to give me a constant feedback of water level in our pond. This information was important to me as the pond capacity is 350000 liters, i want to know how much water i have used in one day for drip irrigation. It is displaying accurate depth of water to an inch. This is exactly what I wanted to accomplish.
- Reviewed in India on 14 February 2020Verified PurchaseWorking perfectly within short range (less than 20cm) but starts disturbing in long ranges (more than 30cm)
- Reviewed in India on 2 April 2024Verified PurchaseThe sensors were not detecting anything.
