The Arduino Nano Hall magnetic sensor detects the presence and strength of magnetic fields, converting magnetic flux into electrical signals. It’s ideal for proximity sensing, speed detection, and ...

Arduino Nano ESP32 project with MicroPython for connecting a AM2315 sensor and Relay and send information for plant irrigation to the Arduino IoT Cloud ...

This post describes the preliminary results of a small Hall-Sensor module. This is widely known as KY-024 module. The KY-024 sensor module I got from an online retailer is inexpensive, and the ...

I recently had to build an infrared close proximity sensor that could tell if something was dropped in a parcel delivery drop box. After some searching, I ended up using a microcontroller and a piece ...
