[Ashish Choudhary] married an Arduino with a display and a pollution sensor to give readings of ... diode and a photodiode to detect and count particles, while a fan moves air through the system.

The common “single-beam” Turbidity Meter (see the design pattern shown below) only monitors light scattered by particles suspended ... old TSD-10 turbidity sensor lifted from a defunct washing machine ...

The microcontroller-based concept was chosen because I wanted to scale the sensor system later to suit other applications. Here is the diagram of my Arduino infrared close proximity sensor. As you can ...

There is no single parameter that determines the quality of a water sample, so the pollution monitor has no less than five different sensors ... turbidity (suspended particles) and temperature.

The Electron's computer-on-a-board includes Arduino-like interfaces for connecting sensors and other electronic hardware, a u-blox cellular module, onboard lithium battery and cellular antenna ...

By simply choosing a wireless sensor gateway for one’s favorite development platform (Arduino, Raspberry Pi or BeagleBone Black) and any of over 20 different types of wireless sensors ...

Aiming at sensor fusion application development, Rutronik has created a single Arduino-compatible board with a plethora of sensors from Infineon, Bosch SE and Sensirion. Called ‘RAB1 – Sensorfusion’, ...

That’s right, these parking sensors are powered by an Arduino board, and the only extra components that were used in the project are a HC SR04 ultrasonic sensor, an active buzzer, and jumper wires.
