The HC-SR04 Ultrasonic Module Distance Sensor from EC Buying is a versatile and reliable device that is perfect for a range of applications. With a power supply of 5V DC and a quiescent current of less than 2mA, this sensor provides accurate and precise distance measurements. The effectual angle of less than 15° ensures that the sensor focuses on the target area, resulting in more accurate readings. With a ranging distance of 2cm to 500cm and a resolution of 0.3cm, this sensor is suitable for both short-range and long-range distance measurements.
The HC-SR04 Ultrasonic Module Distance Sensor is easy to use and can be easily connected to your system. The mode of connection includes VCC, trig(T), Echo(R), and GND. Simply supply 5V DC to the VCC pin, connect the trig pin to the trigger control signal input, and the Echo pin to the echo signal output. The GND pin is the ground wire. This straightforward connection allows for seamless integration into your project.
This sensor is highly reliable and provides accurate distance measurements, making it ideal for a wide range of applications such as robotics, distance sensing, and obstacle detection. The compact size and durable construction ensure that this sensor can withstand the rigors of daily use. Upgrade your projects with the HC-SR04 Ultrasonic Module Distance Sensor from EC Buying and experience enhanced performance and accuracy.
Note: This product does not include any additional accessories or components. Please refer to the product specifications for more information on the dimensions and weight of the sensor.

These ultrasonic transducers are a fantastic deal - I literally had it plugged in and measuring distance within 5 minutes. With some libraries (e. G., NewPing) you can even run the trigger and echo off the same pin. Measurements seem very repeatable, with only a few cm little jitter even at 200cm, and it seemed to support ping at least every 40ms. They do have some side lobes to watch out for though - I was getting some pings off objects up to about 30 degrees off-center. Not usually a problem for clear areas, but may complicate indoor navigation (rather than obstacle avoidance, for which it may simply generate false triggers). I'm a happy hardware hacker, and plan to incorporate several of these into the little rover in working on with my daughter.

My son is working on a 4H project requiring proximity sensors. We ordered this 10-pack of HC-SR04 sensors from EC Buying, and they have been great so far.We've tested every single sensor, and they all work. Their values are all in line with one another which adds to our confidence in their accuracy. We are using these with an Arduino Uno R3.I'm not a fan of how these get shipped (all thrown in a plastic pouch), but it must be fine because they all work!
