DIY motion sensor | Raspberry PI AI - WordPress.com

Mar 26, 2014 · The motion sensor is simply a PIR sensor connected to a 434MHz RF transmitter via an encoder. The encoder uses four bits, in the form of resistors tied to HIGH (+VCC) or LOW (GND). That’s enough for 12 sensors. The ATtiny85 is programmed via an Arduino which allows for devising a smart way of sending the RF data.

PIR motion sensor interface with AVR-microcontroller ...

Mar 23, 2018 · The PIR sensor is interfaced with Atmega32 AVR microcontroller to detect the motion around the environment. Atmega32 considers any voltage between 2V to 5V as logic high. Hence PIR sensor is directly interfaced to the input pin of the controller. The circuit shown above will read the status of the output of the PIR sensor and switch ON the LED ...

Motion Detector - HackSkunk

Solution: Use a PIR Motion detector, a Photodiode, and a Attiny85 to detect motion only in the evenings/during the night. Then, sound an audible alarm in the parents bedroom to alert them. The Build: To begin the build, i took a trip to my local radio shack to pick up some discrete components i required.

PIR wakes up ESP-12 from deep sleep - Everything ESP8266

Aug 04, 2015 · So, PIR connected to ATTiny, ATTiny connected to ESP-12. Both ATTiny and ESP-12 are in a state op deep sleep. The PIR detects motion and sends a positive pulse to the ATTiny. The ATTiny wakes up and resets the ESP-12. It also brings a second line high for the ESP-12 to see that is reset by the ATTiny and not by anything else.

low voltage motion sensor - Electrical Engineering Stack ...

The PIR operates at 3.3v (you can bypass the 3.3v regulator to do this) and the ATTiny will work quite happily at that voltage. Battery consumption is the only other issue here - PIR consumption is the one to worry about here - the microcontroller can run in full sleep mode (micro amps) almost all the time, waking the microcontroller up via an ...

Passive infrared sensor - Wikipedia

A PIR-based motion detector is used to sense movement of people, animals, or other objects. They are commonly used in burglar alarms and automatically activated lighting systems.. Operation. A PIR sensor can detect changes in the amount of infrared radiation impinging upon it, which varies depending on the temperature and surface characteristics of the objects in front of the sensor.

Switch and PIR Triggered Sink Lighting | Hackaday.io

An ATtiny85 is hooked up to two limit switches, a PIR sensor and 11 WS2812 LEDs. One switch is triggered by the faucet handle; the other hides under the cupboards for water-less triggering. Lights go on when either switch is hit, and go off 20 s after motion disappears. Thus it triggers when doing dishes, but not when putting dishes away or walking nearby. I initially tried an IR rangefinder ...
