Combination of Wifi and Ultraschallsensor HC-SR04

Other Hardware Sensors
1

Hello,

I'm a beginner in electronics and I ask me is it possible with the Arduino UNO R3 to combine WiFi and Ultraschall - HC-SR04 module.

The idea behind this is, to send me a signal over wifi, when the HC-SR04 have something. Additional question is the power settings: is it possible to turn on the sensor every 30 sec to save power?

Thanks in Advance

regards

Darko S.

Theoretically: yes. It depends on what hardware you're planning to use for the WiFi functionality but usually it should work.

Additional question is the power settings: is it possible to turn on the sensor every 30 sec to save power?

Yes, but it doesn't make sense as the UNO it using to much power itself to keep it running on batteries for a longer time period. Use a slighter board like the Pro Mini or in your case (as you plan to use WiFi) an ESP8266 based board without an Arduino (you can still use the Arduino IDE to program it).

Thank you very much :DDDD

Can you draw me the plan for the connection?

Thanks

An ESP-01 module should do.

Make sure you have a 3.3V version of the HC-SR04.
