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 ...
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 ...
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 ...
Ultrasonics refers to signals that are above the human hearing span (>20 kHz), and usually in the 40- to 70-kHz range. These signals are used like radar—they’re radiated toward a target and reflected ...
Passive infrared (PIR) sensors are experiencing sustained growth in 2026. This is driven largely by the expansion of smart home technology, building automation, and energy-conscious design. Once ...
Arduino Library to read the ZACwire protocol, wich is used by TSic temperature sensors 206, 306 and 506 on their signal pin. ZACwire obj(int pin, int Sensor) tells the library which input pin of the ...
Abstract: The Smart Automated Zebra Crossing System operationalizes Passive Infrared (PIR) sensors and Internet of Things (IoT) technology with IP camera-based headcount capabilities to foster ...
