Ultrasonic Distance Measuring Sensor
£3.00 (£3.60 inc. VAT)
Ultrasonic distance measuring sensor (HC-SR04) with a crumbliser soldered on so this module can be attached to the Crumble with croc leads.
Requires two connections from A, B, C or D: one to trigger the ultrasonic pulse and one to measure the time for the echo to return. A single programming block reads the distance in cm (introduced in Crumble software version 0.25.0).
