Objective To create an efficient water level monitoring system using an HC-SR04 sensor and Arduino, enabling real-time data collection, visualization, and potential IoT integration for various ...

Some of the best hacks are the ones which seem perfectly obvious in hindsight; a solution to the problem that’s so elegant, you wonder how it never occurred to you before. Of course we also love the ...

This project contains example sketches for an ESP32 that measure distance with an HC-SR04 ultrasonic sensor and temperature/humidity with an AHT2x (AHT25/AHT20-compatible) sensor and upload the ...

The HC-SR04 sonar modules are available for a mere pittance and, with some coaxing, can do a pretty decent job of helping your robot measure the distance to the nearest wall. But when sellers on eBay ...
