Also, any 5-V DC power relay with a rated coil current up to circa 100 mA can be used at its output port (CN1). Figure 2 Schematic diagram shows impulse relay module operating for 5-V DC/500-mA power ...

Arduino Nicla Sense Env is a new sensor module with temperature, humidity, and gas (TVOC, NO2, O3) sensing that follows the launch of the Arduino Nicla Sense ME (Motion & Environment) module over ...

It works in two different modes, Normally Open (NO) and Normally Closed (NC). in our project, we will use it in Normally Open mode which means when the relay is switched off the circuit will be broken ...

The module form factor is compatible with Portenta and MKR ranges and features castellated pins – friendly for automated SMT assembly on application specific carrier boards. Portenta C33 can be at the ...

If you have a bare RGB LED instead of a module in a breakout board, you can make something akin to a module by attaching resistors on each of the color pins. The resistance value varies per ...

Circuit and working The circuit diagram of contactless hand sanitiser dispensing system is shown in Fig. 2. It includes 12V power supply, Arduino Uno (Board1), ultrasoic sensor HC-SR04 (US1), 5V ...

Arduino is the first widespread Open-Source hardware project and, since 2005, has become almost ubiquitous in microcontroller projects. The Arduino Pro line is aimed at the more professional user who ...

Raspberry Pi RP2040 MCU has been used in many boards, but I think I had seen the dual-core MCU in a PLC, or even any industrial products just yet. Sfera Labs Iono RP is a compact I/O module (PLC) with ...

Components Required for the Automatic Irrigation System The project requires very few components and the connection is also very simple. The components are listed below: Arduino * 1 moisture sensor * ...
