Ultrasonic URM07 UART Low-Power Consumption Sensor 20~750cm

Ultrasonic URM07 UART Low-Power Consumption Sensor 20~750cm - Ultrasonic URM07 UART Low-Power Consumption Sensor 20~750cm. An ultrasonic sensor measures distance by calculating the time difference between sending a signal and receiving an echo from an object. It uses echolocation to measure distances, just like a bat.

The URM07 is an ultra-low-power sensor. The effective range is up to 7.5m, and it has a wide range power supply of 3.0 - 5.5V. It is directly compatible with 3.3V or 5V devices such as Arduino, Raspberry Pi. etc. The average operating current is only 5mA and the standby current is only 14uA. According to the principle of ultrasound sensors, the accuracy of the distance value will be affected by the air temperature and wind direction, so using a DFRobot URM07 built-in temperature sensor, you can read the ambient temperature, and automatically calculate temperature compensation. The sensor uses an integrated ultrasonic probe with a detection angle of approximately 60° in a compact and lightweight unit. The unit uses a 2.54mm pitch 4Pin interface, using UART communication, compatible with most common microcontrollers.

URM07 Detecting Angle

URM07 UART ultrasonic distance sensors have undertaken rigorous road testing and optimization. We guarantee that this sensor has first-class response speed, ultra-high stability, the highest sensitivity, and ultra-low power consumption. If you have harsh environmental requirements for your sensor performance in your design, the URM07 is definitely the best choice.

Frequently Asked Questions about Ultrasonic URM07 UART Low-Power Consumption Sensor 20~750cm

Q1: The operation of an ultrasonic sensor

When electrical energy is delivered to the sensor's ceramic transducer, it vibrates. Air molecules are compressed and expanded in waves from the sensor face to the target item by vibrations. Sound is both sent and received by a transducer. The ultrasonic sensor will generate a sound wave to determine the distance, then "listen" for a predetermined amount of time to capture the sound wave's return echo when it bounces off the object.

Q: When would I utilize a sensor that uses ultrasound?

Ultrasonic sensors can be used in situations where photoelectric sensors may not be since they sense sound rather than light. For applications where photoelectric sensors struggle due to target translucence, such as clear object detection and liquid level measurement, ultrasonic sensors provide a fantastic alternative. Ultrasonic sensors are unaffected by target color and/or reflectivity and can function dependably in high-glare settings.

Q: When should I use an optical sensor instead of an ultrasonic sensor?

When detecting transparent objects, liquid levels, or highly reflecting or metallic surfaces, ultrasonic sensors are advantageous. In wet situations where an optical beam may be refracted by the water droplets, ultrasonic sensors also work effectively. However, changes in temperature or wind can affect ultrasonic sensors. Additionally, optical sensors provide for small spot sizes, quick responses, and in some cases, the ability to project a visible spot onto a target to aid in sensor alignment.

Q: Why should I wait for my ultrasonic sensor to warm up before using it?

Before allowing the ultrasonic sensor to warm up, it should not be configured or used. When a sensor is turned on for the first time, the various parts heat up individually as well as the surrounding area and other parts. Warm-Up Drift is the term used to describe the temperature change from a cold start to the operational temperature. The precision of your measurements can be compromised until all parts have stabilized at the ideal operating temperature.
