Motion Controlled Water Fountain for a ... -

· When PIR sensor detects movement it sends message to Radio Dongle plugged to the Raspberry Pi which sends the message to the MQTT server. On the other side MQTT message is processed by the Home Assistant which then using the automation triggers smart plug and starts configured countdown. See project! Each Friday is PiDay here at Adafruit! Be sure to check out our …

How PIRs Work | PIR Motion Sensor | Adafruit Learning System

· PIR sensors are rather generic and for the most part vary only in price and sensitivity. Most of the real magic happens with the optics. This is a pretty good idea for manufacturing: the PIR sensor and circuitry is fixed and costs a few dollars. The lens costs only a few cents and can change the breadth, range, sensing pattern, very easily.

Mini Basic PIR Sensors - Adafruit Industries

· PIR sensors are used to detect motion from pets/humanoids from about 5 meters away (possibly works on zombies, not guaranteed). This sensor is much smaller than most PIR modules, which makes it great for unobtrusive projects. It’s also fully-contained – only needs power, ground, and a resistor to set the delay time – and breadboard or perfboard friendly. Runs on power – so make ...

PIR Sensor (#555-28027) - Adafruit Industries

The PIR Sensor requires a ‘warm-up’ time in order to function properly. This is due to the settling time involved in ‘learning’ its environment. This could be anywhere from 10-60 seconds. During this time there should be as little motion as possible in the sensors field of view. Sensitivity The PIR Sensor has a range of approximately 20 feet. This can vary with environmental conditions ...

PIR With ESP8266 and MQTT : 4 Steps - Instructables

PIR (Passive infrared sensor) or motion sensor is as its name implied detects a heat source that moves. Human, dog, cat moving across the front of the sensor triggers a HIGH signal. Here is a very nice diagram from Adafruit about the PIR sensor. PIR sensor is lost cost, and the response time is instant. The sensor can be configurated into several setups. Three setups covered in this writing ...

Adafruit 189 PIR Motion Sensor - Génération Robots

PIR Motion Sensor by Adafruit: practical and adaptable. Like all PIR sensors, this motion sensor module designed by Adafruit is extremely easy to use and pretty energy efficient. Better still, it offers a certain flexibility since you can: decrease its power requirements and pass from 5 to 3V (with a few soldering operations to bypass the regulator); adjust the motion sensor…
