Prototyping with Microcontrollers, Sensors, and Materials

Prototyping Prototyping involves the creation of an initial model of a product to conduct testing. Whether the product is intended for consumers, government entities, or businesses, it typically starts as a prototype, which may not include all the components or functionalities present in the final market-ready version. Prototypes act as proof of concept, demonstrating that […]

Digital Barometer using PIC Microcontroller and MPX4115A Pressure Sensor XC8 schematic

Digital Barometer using PIC Microcontroller and MPX4115A Pressure Sensor – XC8

The Motorola MPX4115A is an atmospheric pressure sensor powered by 5V and delivers and output from ~0.25V to ~4.75V based on the pressure detected at room temperature (25°C). The device provides a linear output based on pressure. As the pressure rises, the output voltage of the sensor rises as well with ~0.25V represents <15 kPa

Ionization Smoke Detector With Programmable Calibration schematic

Ionization Smoke-Detector With Programmable Calibration

Microchip Technology unveiled the RE46C180—the world’s first Ionization Smoke-Detector IC with programmable calibration and programmable feature selection, and the first with horn synchronization and auto alarm locate. This Ionization Smoke-Detector ASIC also has expanded options for implementing hush operation, and more options for interconnect operation—including with carbon-monoxide detectors. These features enable designers to develop and

Introducing Easy Pulse: A DIY photoplethysmographic sensor for measuring heart rate

When I first built the Heart rate measurement through fingertip project, the infrared LED and photodiode used for finger photoplethysmography were actually from salvaged parts, and therefore, I could not provide specifications for them in the article. As a result of that it takes quite a bit of time to replicate that project with a different set
