The hardware setup shown below includes the Arduino Uno R4, a DHT11 sensor, and the built-in Wi-Fi for email alerts. The DHT11 is connected with VCC to 5V, GND to ground, and the data pin to Digital ...
This section defines the network credentials and server details required for sending the email. The ESP32-CAM connects to WiFi using the SSID and password. The host address, HTTPS port (443), and API ...
Arduino has just announced the Arduino Matter Discovery Bundle (AKX00081), an all-in-one development kit designed to help ...
Abstract: Passive infrared (PIR) sensors are widely used in motion sensing and lighting control. However, stationary occupants always trigger false-negative detects of PIR sensors and result in ...
The library gives control over up to 16 parallel working PIR devices over I2C. The idea for this library came up in a discussion about how to fully cover an area with PIR sensors without blind spots ...
Abstract: In this paper, we use a modified passive infrared radiation or pyroelectric infrared (PIR) sensor to classify 5 different human motion events with one additional “no action” event. Event ...
Connect the VEML6040 sensor to your Arduino board's standard I2C bus. Check the pinout of your Arduino board to find the correct pins. Important: without additional level shifting the VEML6040 is not ...
