Add Reliable Ultrasonic URM07 UART Low-Power Consumption Sensor 20~750cm Sensing to Your Next Build
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.
