How it works is simple: you can track devices using Bluetooth on the ESP32, and through a combination of presence and signal strength, you can define a sensor that changes to an "on" state when your ...

With a fortnight’s struggle, I completed the design of 4 mA to 20mA, two-wire temperature transmitter using a platinum resistance temperature detector (RTD) sensor, as shown in Figure 1. Figure 1 A ...

Rutronik Adapter Board RAB7 Sensor Fusion Arduino shield features seven sensors from Bosch, Infineon, and Sensirion Rutronik Adapter Board RAB7 is an open-source hardware Arduino shield designed for ...

A plastics and rubber industry conference honored several companies for using technology and better communications to try to make their factories safer.

The thermal sensor gives results, is easy to use, and helps make devices smarter, safer, and more efficient. Melexis Redefines Thermographic Sensing with the MLX90642 32×24 IR Array Melexis has ...

Part 2 describes TIA applications in fiber-optic communication systems and makes recommendations for designs that are specific to each application in fiber-optic comms.

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 ...

Arduino simplifies things by only using just one coding language. Here's what you need to get started with developing software for the tiny device.

As explained by Arduino to Go, each color band on the resistor corresponds to a number but this can differ depending on the band's placement. It's not complicated, but the sheer number of colors ...
