Then, finally core unit transmits data to visualization unit. Five sensors have been used in this research such as ECG (Electrocardiography), Oxygen saturation (SPO 2), Passive Infrared Sensor (PIR), ...

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 ...

That said, the Arduino is clearly the better option, as it offers boards capable of accommodating Arduino projects with multiple sensors and modules. There's the Arduino Giga R1 Wi-Fi featuring an ...

This DIY system is made of an infrared touch frame, a two-way mirror, and an HDMI monitor, outfitted with several other main components (Raspberry Pi 4, camera, Amazon Alexa speaker, and some LED ...

Proximity Sensor Switch – Circuit Diagram. The circuit diagram of the wireless load control unit is shown in Fig. 2. This design is based on Arduino Nano board and built around an I2C LCD (module1).

Temperature Analysis Including Headcount is intended to analyze the temperature and headcount of everyone within the sensor's range. In this project, 37°C is used as a base temperature. A person whose ...

The MetaSense A075V USB camera offers 320×240 depth resolution plus an extra RGB sensor, an IMU unit, and a CPU with built-in NPU that makes it ideal for ROS 1/2 robots, while the lower-end MetaSense ...
