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

Edi demonstriert, wie man den HC-SR501 PIR-Sensor mit einem Arduino testet und parametriert. Der Beitrag enthält Anleitungen zur Hardware-Verbindung, Fritzing-Dateien und Beispiel-Code. Ideal, um Reichweite und Reaktionsverhalten des Sensors eigenständig einzustellen und zu testen.

ESP32-Cam and D1 Mini ESP8266 Projects

In this Part of my Blog i will show you some Prjjects 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.
