Tutorial 1: ESP8266 with DHT11 Temperature and Humidity Sensor using Arduino IDE---https://microdigisoft.com/esp8266-with-dht11-temperature-and-humidity-sensor-using ...
Let me introduce another simple microcontroller-based do-it-yourself circuit that detects motion and excites a light source in a flash. The “snooper” here is an ordinary passive infrared (PIR) motion ...
This project uses a PIR (Passive Infrared) sensor to detect motion and displays the status on an I2C Liquid Crystal Display (LCD). When motion is detected, a message is shown on the LCD and printed to ...
Wireless sensor networks are nothing new to Hackaday, but [Felix]’s wireless PIR sensor node is something else entirely. Rarely do we see something so well put together that’s also so well designed ...
Abstract: In this paper, the Arduino based Intruder Detection System employing Rochelle Salt and Pyro-electric or Passive infrared (PIR) Sensor has been proposed. The proposed system employs Rochelle ...
