Die Tücken der ESP32Stromversorgung | ArduinoHannover

· Ich möchte eine ESP32 Cam als Modelbahnlokkamera einsetzten. Die Stromversorgung soll über die Modelbahnschienen mit 20V erfolgen. Spannungsregler von 20V auf 5V ist eingebaut .Jedoch neigen die Kontaktaussetzer der Schienenübertrager zu kurzfristigen Stromunterbrechungen. Ohne diese Aussetzer scheint die Versorgung zu klappen. im Standbetrieb der Modelbahnlok. …

Sensor Component — ESPHome

With this automation you can observe if a sensor value passes from outside a defined range of values to inside a range. For example you can have an automation that triggers when a humidity crosses a threshold, and then turns on a dehumidifier. This trigger will only trigger when the new value is inside the range and the previous value was outside the range. On startup, the last state before ...

Motion Sensor Camera ESP32CAM project Electronics ...

· The ESP32CAM is in Deepsleep mode with external wakeup enable at PIN 13. Whenever the PIR sensor sense any motion within the range the output pin of the PIR sensor becomes high. As the output pin of the PIR sensor is connected with the ESP32CAM pin 13 so ESP32CAM gets the wakeup signal. The ESP32CAM wakes up and take the picture.
