The soil moisture sensor module , built around the LM393 comparator, gives an active-low (L) level output when the soil is dry (determined by a pre-setted threshold value). This digital output (wet ...

This Arduino Project Hub guide shows you how to set up an AMG8833 thermal camera with an OLED display for an Arduino.This sensor is relatively complex to set up, but it works with older Arduino ...

The Pressure Sensor Module incorporates a material called Velostat with the Arduino. This material adds more resistance when more pressure is applied to the material. This module also uses the RGB LED ...

Here is a motor speed sensor module, the major goal is to check the rate of an electric motor. The module can be used in association with a microcontroller for motor speed detection, pulse count, ...

What I meant was building your own pulse sensor (like the one from this post, or getting the ready to use arduino pulse sensor from the kickstarter link) and using it to create the signal used by ...

The [Libelium] team wanted to help people in Japan measure radiation in their surroundings following the nuclear accident in Fukushima. Because of the affordability and seeming ubiquity of the Ardu… ...

Osram has packaged all the optoelectronics necessary for measuring pulse rate and blood oxygen level in a 7.2 x 2.5 x 0.9mm envelope: one photo-diode, three green LEDs, one red LED and one infra-red ...
