nodemcu & pir sensor - Sensors - Arduino Forum

· nodemcu & pir sensor. Using Arduino. Sensors. carlsopa February 4, 2019, 2:42am #1. I am working with a PIR sesnor and a node mcu ESP8266. The general idea is that I put the board into a deep sleep and awaken it with the PIR sensor. The code seems to be working fine, however I beleive I have an issue with the wiring. Signal out on Pir is connected to base on a 337 transistor. The collector …

Hack a PIR Motion Sensor with an ESP8266 – Gnd_To_Vcc

· Motion Sensor. We’ll hack a commercial motion sensor that has enough space to put an ESP-01 and the HLK-PM03 AC/DC converter module inside. We bought our motion sensor for $5 in a local store. When the PIR sensor detects motion, there’s power coming out from the red hot wire that can turn on a lamp or a device. Your motion sensor should ...

IoT Motion Sensor – NodeMCU ESP8266 + PIR » DIY Usthad

IoT Motion sensor Working Theory We have connected the PIR motion sensor to one of the GPIO pins of the NodeMCU ESP 8266. Whenever the PIR detects motion then the output sates of the PIR sensor will change which will be detected by the controller. We have programmed the NodeMCU to make an HTTP GET request to our IFTTT webhooks applet.

PIR motion sensor (HC-SR501) false results with NodeMCU

I have a PIR sensor which I use to detect the motion and turn ON and OFF the lights on the basis of it. I have PIR connected with NodeMCU (ESP8266) based board. I find that sometimes it trigger false positive value. Even when there is no motion. As per my understanding I think any of the following reasons can be there: I have NodeMCU close to it. So may be because NodeMCU heatness triggers …

Using PIR Motion Sensors With the Raspberry Pi and Python

· While PIR motion sensors tend to be much the same, these pins may be ordered differently on another model. Check your component’s specifications if you’re unsure. Connect the Raspberry Pi’s 5-volt power pin to the positive power rail of your breadboard, then the ground pin to the negative rail. Then, with the lens facing away from you, connect the motion sensor’s power pin to the ...
