Button Module: A switch that can control the passage or open circuit. Generally, it is used as a passage and released as an open circuit. Pin Details ESP32 Attributes Description GPIO25 1-Wire Button 2. RGB Module Pin Details ESP32 Attributes Description GPIO25 1-Wire WS2812 3. Pir Human Detection Module PIR sensors are commonly used for security alarms and automatic lighting applications. PIR sensor detects general motion but does not provide information about the mover or moving object Pin Details ESP32 Attributes Description GPIO25 1-Wire Pir infrared sensor 4. DHT11 Module: It is a sensor combined with temperature and humidity sensing components. The built-in processor converts the measured temperature and humidity data into digital signals, and then sends the data. Pin Details ESP32 Attributes Description GPIO25 1-Wire DHT11 5. Door Contact Door Contact is a device for security alarm. It consists of a wireless transmitter and a permanent magnet. It is used to detect whether doors, windows, drawers, etc. are illegally opened or moved. Pin details ESP32 Attributes Description GPIO25 1-Wire Door 6.
