Measures from 3cm to 3m Flowcode component available Fits onto E-blocks Sensors Motherboard
This board has both an ultrasonic transmitter and receiver. The transmitter is driven by an on-board 40KHz oscillator which is enabled by the host microprocessor. The receiving sensor signal is amplified and provided as an analog signal to be processed by a single-channel ADC of the microprocessor. By measuring the time delay between enabling a transmit pulse and receiving an echo, the distance of objects in a range of around 3cm to 3m can be determined.
The connection pinout of this module allows it to plug directly into the E-blocks Sensors Motherboard. The 0.1" pitch of the pins makes it easy to add this module to any standard breadboard also.
