Okdo Ultrasonic Module Ultraviolet (UV) Sensor Micro:bit and Arduino

The Okdo ultrasonic transmitter and an ultrasonic receiver can consider it as an ultrasonic transceiver. Familiar with sonar, when the 40KHz ultrasonic wave generated by the transmitter encounters the object, the sound wave will be emitted back, and the receiver can receive the reflected ultrasonic wave. It is only necessary to calculate the time from the transmission to the reception, and then multiply the speed of the sound in theair(340m/s)tocalculate the distance from the

Very common in robotics projects and very useful for automation, interactive art and motionsensing
With four fixing holes, it can be easily fixed on other devices such as servo plastic platform
Compatible with all 40-pin Raspberry Pi motherboards
