US-100 Distance Sensor Features The US-100 is an ultrasonic transmitter and receiver module used to measure distance. The sensor operation is very simple. You only need to measure the return time of ultrasonic waves in order to measure the distance. Then you can divide this time by 2 and multiplied by the sound speed. The sensor measuring range is about 2 to 450 cm. Note The US-100 module has 2 different communication protocol. Method 1: use serial communication Method 2: use Trigger and Echo (similar to ...

RCWL-0516 Microwave Radar Sensor Features The RCWL-0516 microwave radar motion detection sensor is used to detect motion at a maximum distance of 9 meters. The viewing angle of this module is about 270 degrees and it has a digital output. You can install a photocell sensor on this module. Note The RCWL-0516 module does not work properly at a distance less than 20 cm. Note This module can measure a maximum distance of 7 meters by default; but you can adjust distance by placing a resistor behind the board. No...
