Height Measurement By Ultrasonic Sensor Using Arduino

Height Measurement By Ultrasonic Sensor Using Arduino. HCSR04 ultrasonic sensor The HCSR04 ultrasonic module is a module that can provide noncontact measurement within the range of 2cm to 400cm with ranging accuracy that can reach 3mm It works on the principle of echolocation The ultrasonic sensor as a trigger and an echo pin The arduino provides a high signal of 10microseconds to this pin.

The Arduino Sensor Kit is made for Makers who have just started using Arduino to explore the vast space of electronics and programming This kit teaches how to connect and program basic Grove modules that includes both sensors and actuators Grove is an opensource modulated and readytouse View full details $2850 | / Add to cart Quick shop $1750 | / Grove HCHO.

Each sensor provides a separate analog voltage output The sensor board is an infrared emitter/receiver that is able to differentiate between a dark surface (with low IR reflectivity – 33V to 5V) and a light surface (with high IR reflectivity – 0V to 05V) However this range can vary depended on the installed height of the sensor board.

The “Max dist” that you set in the properties of the PIN type “Usund sensor” in application HAL must match the scale you set in ThereminoRadar The slot 1 is used to move the servo (set your PIN as Servo16) The slot 2 is used to read the ultrasonic sensor (set the PIN as “Usound sensor”).

100m of wire has too much inductance resistance and capacitance for a signal from the Arduino to reach the sensor or for a reply from the sensor to reach the Arduino You could do it with two Arduinos and a radio link between them and the HCSR04 connected by short wires to one of them or the two Arduinos could be connected using RS485 communication shields and 100m.
