It transmits ultrasonic ... circuit which turns a large voltage into a smaller one. Using just two resistors and an input voltage, we can create an output voltage that is fraction of of the input.

Components required for this project are Raspberry Pi (or Raspi) 2, HC-SR04 module, 330-ohm and 470-ohm resistors, and some jumper wires. Working of HC-SR04 ultrasonic sensor is fairly simple. Circuit ...

(Refer Fig 2,3) Fig 2 Fig 3. Now connect the ultrasonic sensor as in the circuit diagram (Refer Fig 4). Then the camera in with a raspberry pi using the ribbon cable after this you set the camera and ...

It is used to control the level of water in a tank using a Raspberry Pi 4, ultrasonic sensor, reservoir, tank, submersible pump, MOSFET switch and power supply. The output step time response of the ...
