    HC-SR501 PIR Motion Sensor Test with Arduino Uno and Breadboard

    11. August 2025By

    To figure out how to configure an HC-SR501 motion detector, I built a breadboard with a test circuit. This requires an Arduino Uno, the HC-SR501 sensor, an LED, a passive piezo buzzer, a 220 ohm resistor, a power supply or USB Cable to power the Arduino, and some jumper cables.

    On the Arduino you have to Upload the cpp Code from the INO-File to switch the Buzzer and the LED on and off when Motion ist detected.

    I put the whole thing together in Fritzing, and it’s available here also as an fzz file for download.

    The HC-SR501 motion detector has two potentiometers for setting values:
    1.) Sensitivity (SENS) → controls the range (~3m to ~7m)
    2.) Time delay (TIME) → controls how long the OUT pin remains HIGH (from approximately 2 seconds to several minutes)
    With the test setup, a suitable value can be determined for what you ultimately want to build by changing the potentiometer setting.

    Have fun trying it out and modify it for your own Requirements!

    Best regards,

    Edi

    CPP-Code for programming the Arduino One
    (INO-File Downlod here):

    const int pirPin = 2; // HC-SR501 Ausgang
const int ledPin = 5;  // LED Pin
const int buzzerPin = 4; // Summer Pin
int pirState = LOW; // Aktueller Zustand des PIR Sensors

void setup() {
  pinMode(pirPin, INPUT);
  pinMode(ledPin, OUTPUT);
  pinMode(buzzerPin, OUTPUT);
  Serial.begin(9600); // Für Debugging
}

void loop() {
  pirState = digitalRead(pirPin);

  if (pirState == HIGH) {
    digitalWrite(ledPin, HIGH);
    digitalWrite(buzzerPin, HIGH);
    Serial.println("Bewegung erkannt!");
    delay(1000); // Kurze Pause
    digitalWrite(ledPin, LOW);
    digitalWrite(buzzerPin, LOW);
    Serial.println("Pause...");
    delay(2000); //  Eine längere Pause
  }
}

     

    Here you will find the Fritzing File:

    It was built with Fritzing Version 1.05

  • ESP32-Cam and D1 Mini ESP8266 Projects

    27. Juli 2025By

    In this Part of my Blog i will show you some Projects that use the ESP32 Cam and the D1 Mini NodeMcu with ESP8266 Modules. There are a few things that this Controller are good for.

    I have some D1 Mini NodeMcu with ESP8266 to control Temperature, Humidity and Airpressure inside and outside of my House. They all have a rechargeable Battery to function for a few Weeks or Months. Captured values are stored in an InfluxDB. The resulting Curves can bo viewed with Grafana. With Node-Red i´vs programmed Dashboards to visualise the Temperature, Humidity and Airpressure with Gauges and Charts.

    The ESP32 Cam can be used as a Live Cam, Cam with automatic storing Pictures to a SD Card or send Photos via Email. Also it can ba combined for Examlpe with an HC-SR501 PIR Motion Detector to send Photos via Email when a Movment ist recognized.

    There are many Projects that can be set up with these Controllers

    Have fun and be creative to make your own things

  • Tasmota Plug – Control with Node-Red and MQTT

    18. Mai 2025By

    Here you will find some Projects to control Tasmota Plugs with the help of Node-Red and MQTT. Requirements are an RaspberryPi ore a Server on which Mosquitto, Node-Red with Dashboard is installed. The Tasmota Plugs should be configured to work in your MQTT Environment, so you have to use Topics, that will fit your naming themes.

    Tasmota is an open source firmware for Espressif ESP8266, ESP32, ESP32-S or ESP32-C3 chipset based devices created and maintained by Theo Arends.

    Tasmota Logo

    You can flash Tasmota Plugs with the Tasmota Firmware: https://tasmota.github.io/docs/

    Here you can see the Blog Posts that i´ve already published

  • Keep your basement dry – WITHOUT electricity costs

    18. Mai 2025By

    If you have the problem that a room in your basement is damp, this project might help you.

    Keep your basement dry – WITHOUT electricity costs with an “Digital 2-in-1 Dehumidifier” (Sichler electric dehumidifier, dehumidifier & air purifier model: LFT-200 or any other dehumidifier of your choice thas can be switched on / off via the powercord)
    => Control the dehumidifier trough a Tasmota socket and Node-Red, Mosquitto via MQTT on a Raspberry Pi. Switching times are based on adjustable thresholds for battery charge.

    Requirements:

    • Raspberrypi with Node-Red with Dashboard and Mosquitto MQTT Broker installed
    • PV system with batteries: home power station E3/DC
    • RSCP2MQTT installed on the Raspi [(https://github.com/pvtom/rscp2mqtt)] to get Values from the Station
    • Tasmota socket with MQTT switched on and configured for the Mosquitto Broker
    • “Digital 2-in-1 Dehumidifier” or any other Dehumidifier which can be controlled with the Tasmota plug

    The Dehumidifier i´m using:

    Picture of the Dehumidifier

    Picture of the Dehumidifier

    Shop where you can buy the Dehumidifier

    Installation

    Verify that the above Requirements are met.
    Import the flow into Node-RED.
    Make corrections in the Nodes for your System:
    Activate and test the flow.

    Usage

    The flow runs automatically in the background and monitors the incoming values form the PV System.
    If the adjusted Value are reached, the Dehumidifier will start working and drying the Air. If the values are not met it will stop.

  • Window- Doorsensor Monitoring with ZigBee2MQTT, Node-RED on a Raspi

    5. April 2025By

    Overview

    This Node-RED flow is designed to monitor a ZigBee-based WC (restroom) window sensor. It detects the window status (open/closed) and monitors the sensor’s battery level. Relevant state changes trigger Pushover notifications. Now a new Version is online V1.1 with little improvements in the Dashboard when the flow starts.

    Features

    • Window Status Detection: Identifies whether the window is open or closed.
    • Battery Status Monitoring: Keeps track of the sensor’s battery level.
    • Notification System: Sends Pushover notifications when the sensor contact is open for a adjustable time, when the sensor will be closed or the battery level is low.

    Requirements

    • Node-RED installed
    • ZigBee sensor compatible with Node-RED (i have used the Aquara MCCGQ11LM)
    • Pushover credentials to use the notification feature

    Installation

    1. Install Node-RED your desired system.
    2. Required Nodes: Dashboard, Pushover, ZigBee2MQTT, node-red-contrib-ui-led
    3. Import the flow into Node-RED.
    4. Create an Pushover Account if you don´t have
    5. Configure the required Pushover Api Node with your credentials.
    6. Activate and test the flow.

    Usage

    • The flow runs automatically in the background and monitors the sensor.
    • A push notification is sent if the window is opened for an adjustable time, when it ist closed or the battery is low.
