Product Description
The HC-SR04 ultrasonic sensor is an affordable and super-popular sensor that measures the distance between itself and an object located in front of the sensor. Very simple to use, it returns the distance in centimeters or inches.
In this variation, it comes on a board with an Attiny microcontroller that sends readings from the sensor as a digital signal via the easyC connector to the microcontroller, which makes its connections a piece of cake.
Product features
easyC
easyC is a system for simple connection of microcontroller boards, sensors and actuators that enables fast prototyping without the possibility of error. The connection between the modules takes place with simple cables. easyC is based on I2C communication. Read more here.
