This project connects a PIR sensor to IFTTT (If This Then That), allowing you to trigger thousands of smart home actions. When motion is detected, you can turn on lights, send notifications, log data to spreadsheets, control smart plugs, or trigger security cameras.<\/p>\n
Difficulty:<\/strong> Intermediate An ESP32 detects motion from a PIR sensor and sends an HTTP request to IFTTT’s Webhooks service. IFTTT then triggers any action you have configured. Since the ESP32 uses Wi-Fi, it needs to be within range of your network, but the IFTTT integration works from anywhere.<\/p>\n VCC<\/th>\n 3.3V<\/th>\n GND<\/th>\n GND<\/th>\n OUT<\/th>\n GPIO 4<\/th>\n<\/tbody>\n \u8868<\/p>\n This IFTTT integration opens up countless possibilities for your PIR sensor.
