URM07 - UART Ultrasonic 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 effect 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 & 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, yyou can read the ambient temperature, & automatically caulculate temperature compensation.

The sensor uses an integrated ultrasonic probe with a detection angle of approximately 60 degress in a compact and lightweight unit. The unit uses a 2.54mm pitch 4 pin interface, using UART communication, comptabiel with most common microcontrollers. 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 sensitivty & ultra lower power consumption. If you have harsh environmental requirements for your sensor performance in your design, the URM07 is definitely the best choice.
