Arduino Mega Conductivity Sample Code //This code was written to be easy to understand. First test using a 5V DC signal on the conductivity probe. 5 and PM10 standards. nextpcb. Also the output can be connected to an A/D converter without alot much grrrrr. In this tutorial this sensor is connected to Arduino to achieve this function.
Gravity: Digital PIR (motion) sensor designed to work with Arduino and Raspberry Pi. Pyroelectric infrared motion sensor can detect the infrared signals from a person or animals which are moving, and can output the switching detection signals. Therefore it can be applied to a variety of occasions which need to detect the movement of a persons body. Conventional pyroelectric infrared sensors ...
This is a simple to use arduino motion sensor. Power it up and wait 1-2 seconds for the sensor to get a snapshot of the still room. If anything moves after that period, the 'alarm' pin will go low. This sensor checks for infrared heat in it's detecting angle. Human body, pets and several other thing
The PIR Sensor senses the motion of a human body by the change in surrounding ambient temperature when a human body passes across. Delay Time Adjustable: 5 seconds to 18 Minutes. Once the motion is seized , it sends a “low” digital value to the Arduino through the digital IO port of Sensor Shield
