To be frank, using a microcontroller is probably overkill for most motion detector safety light circuits because the PIR sensor module itself can handle the ... on-board voltage regulator, and Arduino ...

Using motion detectors and an ... Here is the circuit for the Sparkfun Active Low style sensor. PIR Pin “+” connects to Arduino +5 one side of the 10K Resistor Connects to Arduino +5 PIR ...

Makers and developers looking for a motion sensor ... Infra-red (IR) sensor that can pick up signals from a 38kHz remote control, which means that you can control your Arduino circuit wirelessly ...

If you are designing your own intelligent “Graden Computer” with an optional digital plant moisture sensor/water pump controller that lights an LED to alert the user when it is time to water a potted ...

It works great for any type of motion alarm system. Arduino: The Arduino module is one of ... temperature sensor, and power supply, you can create a circuit that controls and monitors your air ...

With that module ... on a circuit which can provide the board power from a battery or a USB cable, while also managing the battery’s charge. As for sensors, it has a light sensor and an optional ...

This is a firmware application written in C++ using Arduino and Adafruit libraries. It sleeps in low power mode until, activated by the motion sensor, it takes a picture. Images are posted to ...

According to [Mathieu], the answer is also yes, but only if you ignore the datasheet circuit and build this amplification circuit for your dirt cheap Doppler module. The module in question is a ...

It’s a fairly simple project, too: just hook an Arduino Uno up to a motion sensor and an electronic switch called a relay, then plug in your fan, and you’re good to go. If that sounds ...
