VCC is the power supply pin of the soil moisture sensor that can be connected to 3.3V or 5V of the supply. But do note that the analog output will vary depending on the provided supply voltage. GND is ...

This is a gas level measurement using gas sensor (MiCS-4514) and Oxygen Sensor. We used Arduino Mega 2560 to read the data from sensors and to print those data on a serial monitor. It is a simple ...

Connectors and lead wires provide the electrical connection between the coils of an LVDT position sensor and signal conditioning electronics. Choosing between a connector and lead wires, when ...
