SEN0153, Ultrasonic Sensor, UART Low-Power Consumption, for Arduino and Raspberry Pi Board

URM07 UART low power consumption ultrasonic sensor (20 to 750cm) is an ultra low-power sensor with effect range is up to 7.5m. It has a wide range power supply of 3.0 to 5.5V. It is directly compatible with 3.3V or 5V devices such as Arduino, Raspberry Pi. The average operating current is only 5mA and 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 4 pin interface, using UART communication, compatible with most common microcontrollers.
