This is an Arduino-based Proximity Sensor circuit wired using the popular HC-SR04 Ultrasonic ranging module,used here for non-contact object detection purpose. The HC-SR04 module includes ultrasonic ...

This system demonstrates water level and temperature monitoring on a 10.92cm (4.3-inch) TFT LCD using graphics and colour-changing animation of water filling a tank, along with a rising temperature ...

Here is a tested Arduino project that uses 3 sensor probes as water level indicator with 3 leds and one LCD display + a simple controller that turns on a motor when the water has reached the desired ...

[Klaus] wanted some sort of aid for parking his car, and after running across a $4 ultrasonic sensor, decided to build his own speaking distance sensor (.de, Google Translation). Inside [Klaus]’ ...

We are currently in the process of putting in a backyard pool. This is an in-ground gunite pool. I inquired about an auto-fill system from the pool builder but he talked me out of it. He explained ...

The U3M ultrasonic "Mini Probe" level sensor has a 4 to 6-in. operating range and extends 2 in. above the tank or drum surface. The device's PVC housing allows for a 40 to 60°C operating temperature ...

This one is an unusual smart home project, potentially - how to monitor a fish tank’s health with an AI-enabled ultrasonic sensor system. The detailed project is highlighted on Hackser.io and features ...

The LPU-2428 Loop-Powered Ultrasonic Level Sensors obtain all operating power from the 4-to- 20-mA process loop. An internal microprocessor performs volume, flow, and totalization calculations. The ...
