Circuit Diagram for Sound Sensor Module. The schematic diagram for the Sound Sensor module is shown below. The schematic itself is very simple and needs a handful of generic components to build. If ...

An infrared proximity sensor or IR Sensor is an electronic device that emits infrared light to detect objects and motion in Arduino projects. This active IR sensor module is perfect for obstacle ...

This articles describes how you can use I2C (TWI) communication, Arduino and temperature sensors to measure 3 different temperatures. It can be very helpful when you want to measure the outside, ...

I2C_Broadcast: This code enables the master Arduino to send a message to all connected slave Arduinos simultaneously, allowing for system-wide commands, such as activating all devices or triggering a ...

This project showcases the integration of Arduino with a CM1106 CO2 sensor to measure carbon dioxide (CO2) levels. The data collected from the sensor can be transmitted to a Jetson device for further ...

There’s a CdS sensor and a TSL230R Lux sensor for that. An op-amp circuit can measure the sound level in the room via one of the Arduino’s ADC pins. And finally, an RTC board is used for time ...

This is a simple arduino project for a soil moisture sensor that will light up a LED at a certain moisture level. It uses Arduino Duemilanove microcontroller board. Two wires placed in the soil pot ...

A piezo buzzer and a TCS34725 color sensor, mounted on a small breakout board, are connected to an Arduino Nano. This prototype system was developed as part of the course “ From Sensor to Report ” at ...
