We’ve seen a few projects use the WiShield from async labs. It’s a WiFi module packaged in the familiar Arduino shield form factor, and costs $55 USD. For the hardcore hackers out there ...

The “w” in the name is for WiFi as the built-in ESP-32 module then takes the moisture reading and sends an update wirelessly via MQTT. Depending on the IQ of your smart-home setup, you could ...

The hardware is consists of an Arduino microcontroller (here an Arduino Uno R3) and a pre-wired soil moisture sensor module. The soil moisture sensor module , built around the LM393 comparator, gives ...

Then, an Arduino board might be ... t need to buy and work with separate modules. The R4 WiFi is also a more sensible choice for more sophisticated multi-sensor projects that may need higher ...

The Arduino Sensor Kit is a versatile and user-friendly addition to the Arduino ecosystem. Its plug-and-play design, combined with a wide array of sensors and modules, makes it an excellent choice ...

The Arduino Nano Connector Carrier is a compact add-on board designed for the Arduino Nano boards to allow easy connection to ...

The microcontroller-based concept was chosen because I wanted to scale the sensor system later to suit other applications. Here is the diagram of my Arduino infrared close ... proximity sensor to ...

The Pressure Sensor Module incorporates a material called Velostat with the Arduino. This material adds more resistance when more pressure is applied to the material. This module also uses the RGB LED ...
