ESP8266 and PIR example in Micropython - esp8266 learning

ESP8266 and PIR example in Micropython. In this example we look at a PIR example in Micropython for an ESP8266. Once again we use uPyCraft and again we use Wemos shields. Lets remind ourselves about the PIR. A passive infrared sensor (PIR sensor) is an electronic sensor that measures infrared (IR) light radiating from objects in its field of view.

IoT Motion Sensor – NodeMCU ESP8266 + PIR » DIY Usthad

Connect GND of PIR sensor to the GND of NodeMCU.; Connect the VCC of PIR sensor to the of NodeMCU.; Connect the OUT of PIR sensor to the digital pin D2 (GPIO 4) of NodeMCU.; Note: Some PIR sensors will work only from 5v above so if you are using such a PIR sensor then instead to connecting the VCC of PIR to of NodeMCU connect it directly to separate 5v supply.

PIR With ESP8266 and MQTT : 4 Steps - Instructables

And on the subscriber side, and the full code to upload to ESP8266 on GitHub: #define mqtt_port 1883 #define subscribe_topic "sensor/door/pir" #define SENSORNAME "One1W" In the video, you can see that the HIGH status of PIR retained about 5-6 seconds after the last motion while the subscriber (LEDs) is ON for 12 seconds.

ESP8266, Deep Sleep mode test, wake up with a PIR motion ...

· The ESP8266 module has the deep sleep mode which allows to put it in hibernation to save the battery. You can wake up the module at regular intervals to make measurements and publish them on a server. The RESET pin (RST) is also used to wake the ESP8266. For example, the rising edge (the signal) of a motion detector (PIR) can be used. In this tutorial we will see the adaptations to the …
