The power supply can be realized either via USB or by attaching a battery to the GPIO pins of the ESP.\n\nOne ESP (+PIR +HC12) acts as the motion detector and sends a signal to the other ESP (+HC12 +Buzzer), which then gives out an acoustic notification.\n\nThe range, depending on the set transmission power, can be \u003e1km (outdoors). The price of the parts was around 92k sats (+soldering iron and 3D printed cases).\n\nThe .ino source files can be compiled and flashed to the ESP with the Arduino IDE.\n\nAlso, make sure your HC12 module works correctly; many Chinese clones need a simple fix to function correctly:\nhttps://ytb.trom.tf/watch?v=ZfBuEAH-Q8Y\n\n![IMG_20230603_231545_354_1](https://github.com/f321x/wireless_motion_sensor_esp32/assets/51097237/9eb05d29-a684-4477-bcfe-2f4d6cd95a67)\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Ff321x%2Fwireless_motion_sensor_esp32","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Ff321x%2Fwireless_motion_sensor_esp32","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Ff321x%2Fwireless_motion_sensor_esp32/lists"}
